ENVIRONMENTAL STRESS
(attitude
and behavior determinants, basic
ways to prevent stress, potential
stress factors)
The
Attitude & Behavior Determinants
(temperament,
treatment,
environment)
Throughout our
years of rescue work, which includes networking with rescuers internationally,
we've come to realize that quite often, when a chin is suffering from
health or behavioral problems, it's due to stress. People
who over-generalize from their experience with easy-going, well-adjusted
chins probably won't understand the need to address the subject of
stress and its consequences, because indeed, those easy-going, well-adjusted
chins are more adaptive and resilient. But this is not representative
of the common experience, as chinchilla
rescue workers and anyone who's been on a forum and watched chinparents
recycle the same stress-related health and behavioral problems can
attest to.
When we refer to environmental stress, we mean anything external to
the chin that affects him: how he's treated and cared for, what his
environment is like, and not just the physical environment but who
and what is in it. Chinchillas that are affected by environmental
stress often exhibit health (because stress weakens the immune
system) or behavioral problems that include, among other things:
whitish eye
goop, constipation
or diarrhea, fungus,
anti-social
(chasing and pulling fur, urine-spraying, biting) behavior
directed at cagemates (causing conflicts)
or the chinparent, lethargy, acting depressed and withdrawn, weight
loss, excessive dominance mounting,
excessively marking
territory with urine, fidgeting behaviors such as obsessive chewing
of cage bars, hammock, water bottle, etc., and neurotic behaviors
such as
fur-biting, pacing in circles or somersaulting.
Environmental stress is OFTEN the cause behind
a wide range of health and behavioral problems.
Besides being affected by environmental stress factors,
a chin can also suffer from health and behavioral problems that originate
with the chin himself, internal factors, such as when a chin has a
particular sensitivity to a certain brand of dustbath
that gives him eye
irritations, or when a chin is recovering from a recent operation,
illness or injury and the stress of recovery (especially if not
on pain medication) causes him to fur-bite or to act anti-social
in self-defense. In the event of the latter, when a chin is in recovery
from something stressful or traumatic, extra measures should be put
into place to ensure maximum comfort, security and tranquility; providing
TV
helps ease stress and boredom. It is very important to rule out any
potential internal cause before assuming and addressing a health or
behavioral problem from the environmental stress angle, because a
chin that is ill or suffering should see a vet without delay.
This section on Environmental Stress takes a broad approach, because
the chinparent needs to apply their analytical skills and intuition
to troubleshoot within the context of their particular situation.
Often chinparents don't realize there is an environmental stress factor
at work until after one of the aforementioned
conditions develops, sometimes in a serious or chronic way, and then
the focus is often on "how do I make it stop" (treating
the symptom) rather than "what is causing this to happen"
(addressing the problem). To resolve a stress-related
problem, it's necessary to pinpoint and address the underlying cause,
because treating the symptom (fur-biting, weight loss, anti-social
behavior, etc.) in isolation of understanding and treating the
actual problem usually fails and can even make matters worse. Foresight
and prevention
are best, of course.
This section is not meant to give the impression that all chinchillas
are super-fragile, neurotic, nervous wrecks. Generally speaking,
chinchillas are adaptive, resilient animals, HOWEVER, some are more
susceptible to the consequences (health and behavioral problems)
of environmental stress. By examining the determinants
that shape a chin's attitude and behavior, we can better understand
and potentially predict how environmental stress will affect a particular
chin's ability to adjust and cope in life situations:
TEMPERAMENT
...whether the chinchilla is easy-going, high-strung, etc.
For instance, a chinchilla with a naturally high-strung (should
be regarded as NFB)
or oversensitive temperament is more likely to be negatively
impacted by environmental stress than a chinchilla with a calm,
easy-going, mellow temperament. Behavioral
rehabilitation can reassure a high-strung or oversensitive
chin and help him gain confidence in his ability to cope.
|
TREATMENT
...how the chinchilla has been cared for (his needs
on all levels) by people, both past and present. If the
chinchilla came from an abuse or neglect situation or if he
was treated well, given a large cage and frequent
exercise
and is now relegated to
a small cage and is given little attention, this type of thing
will have a direct bearing on the chin's current outlook and
attitude. If a chinchilla was handled roughly by their previous
chinparent, say it was a man as opposed to a woman, he may then
generalize about the human sexes and practice anti-social
behavior towards men only in a new home.

|
ENVIRONMENT
...what kind of environment the chinchilla has been in (underactive,
moderately active, overactive), both past and present |
| |
Underactive- e.g.,
largely ignored, almost nothing to do or play with, no sounds,
music, nothing to watch, etc.
|
| |
Moderately Active-
e.g., regular out-of-cage exercise time and bonding, an exercise
wheel, variety of chew toys and TV at night that's not too loud,
some quiet and solitude for daytime sleep, etc.
|
| |
Overactive- e.g.,
prying pets, constant loud or intimidating noise and traffic,
frequent rough handling, disregard for the chin's need for daytime
rest, his basic needs sometimes neglected, etc.
|
It's important to
realize that an environment of perpetual, unrelenting boredom
(underactive) is just as nerve-wracking and stressful
for a chinchilla as one that is noisy and chaotic (overactive),
and both cause similar health and behavioral problems. For instance,
fur-biting
is common in chinchillas from either an underactive or overactive
environment. A moderately active environment
is best, some activity and noise is stimulating without
being overwhelming or stupefying, it desensitizes the chinchilla
just enough so he can cope with change or the unexpected without
being traumatized by things like thunderstorms, visitors, when
their chinparent takes a trip and they get a pet sitter, or
a ride to the vet. The chinchilla's curious, intelligent mind
craves some environmental stimulation but BOTH
chaos and boredom are problematic.
When a chinchilla comes to a new home from a previous environment
that was underactive OR overactive, he'll need a few days to
a week of time in a quiet room with soft music, some mellow
TV,
the First Contact Procedure
and no other household pets
prior to being brought into the mainstream of a moderately active
household. He'll also need at least a week to settle in and
feel safe and comfortable with his new chinparent before being
introduced
to a new cagemate.
This transitional period is necessary because the chin from
an overactive environment will need a chance to rest his nerves
and regroup and the chin from an underactive environment isn't
prepared to handle a lot of stimulation all at once. Too much,
too soon can overwhelm the chin from an underactive environment
and lead to stress-related shock.
It will take some intuition on the part of the chinparent to
determine when their new chin is ready for more environmental
stimulation, a larger cage,
etc., but it's always best to start out with less stimulation
or a familiar cage size and then work up from there to allow
the chin to gradually transition to an improved lifestyle. |

Basic Ways to Prevent Environmental Stress
Read this section on Environmental Stress thoroughly and ensure your
chinchilla has a moderately
active environment in which all his needs (The
Essentials) are met with unfailing reliability. The Essentials
include regular out-of-cage exercise,
daily interaction
and sufficient daytime rest.
A large cage
to accomodate running and playing, a variety of chew
toys, at least one hideaway
per chin and a cage wheel
will help decrease stress and boredom inside the cage while TV
during waking hours will provide environmental stimulation when the
chin isn't actively engaged in out-of-cage exercise and interaction.
Also, covering the chin's cage (as described on Routines)
will go a long way in providing a sense of security and privacy that
greatly reduces stress.
Providing distractions (chew
toys, wheel,
TV)
to prevent boredom is crucial. Chinchillas
are far too intelligent to be caged for long periods of constant,
stupefying boredom and when they have lots of time and nothing interesting
to do, they may obsess or instigate trouble which can easily lead
to neurotic behaviors such as
fur-biting, pacing in circles or somersaulting, fidgeting behaviors
such as obsessive chewing of cage bars, hammock, water bottle, etc.,
or cagemate conflicts.
Introduce any MAJOR change, such as a change of chinparents, a move
to a different living environment or an introduction
to other chins, slowly if at all possible. Having a "familiarity
connection" helps, such as when a chin moves from one home to
another and both homes have TV for him to watch, or if the chin's
cage makes the transition with him.
Gradual adjustments are best and this can prevent stress-related
shock, a condition brought on when the chin perceives his situation
to be inescapable, hopeless, and completely overpowering of his ability
to cope. Stress-related shock may happen right away, as an immediate
reaction to severe stress, or the chin may expire days later when
his heart just gives out from cumulative, prolonged stress. If addressed
early, the condition may not result in death. Symptoms are only relevant
when they occur within the context of a major, stressful event or
change and they range from extreme lethargy to extreme activity to
seizures. Stress-related shock is NOT common, but chins that are high-strung
or oversensitive, that have come from an abuse situation, or that
were kept in an underactive or overactive (chaotic) environment,
per the attitude and behavior determinants
described in the previous section, are more vulnerable to ill effects
from an abrupt, major change. Chins can
be very adaptive, but in order to cope with change, they should have
a gradual adjustment.
Be aware that it is VERY typical for chins to
be reluctant or suspicious of change or something new, but
this doesn't mean that they don't like it, they just need TIME to
adjust. This perspective derives from their position as a relatively
powerless prey animal, it's also why they appreciate routines so much,
because what is safe and familiar is comforting and doesn't challenge
their ability to cope. This does NOT mean that any change is bad and
that anything new or improved should be withheld, chinchillas can
and do adjust if allowed the time to do so and only then will their
preference for the old or the new become clear. Especially if a chin
is being transitioned from something harmful or unsafe, like a bad
diet
or an unsafe wheel,
to something better, then it is absolutely necessary to see to it
that the changeover successfully takes place. Don't allow your chin
to continue being exposed to something that's bad for him just because
he appears to reject the new when in reality, he's only needs a chance,
some TIME, to adjust.
Chins typically enjoy non-threatening change
in their environment, they may just need time to adjust and
some chins adjust more quickly than others depending on factors like
their age, health and temperament. For instance, an older, high-strung
and sight-deficient chin will be more likely to begin fur-biting
(from stress) when an additional household pet
is introduced than a younger, mellower chin whose sight is intact
and who can better assess and adjust to the change. It's also a good
idea to invite your pet sitter over a few times to become acquainted
with your chin before going on a trip and leaving him entirely in
the pet sitter's care. If the chin will be staying at the pet sitter's
while you're gone, take him over there to get acquainted with the
pet sitter's environment prior to dropping him off for a prolonged
stay.

Changes such as a new cage
location, a new movie
or TV show, a new wheel or different type of chew
toy are usually welcomed with great enthusiasm and enjoyment.
If something is changed and the chin has been given awhile to adjust
(it can take time!) but it becomes clear that the change is causing
the chin to exhibit stress-related health and behavioral problems,
then the change (just be sure you've pinpointed the real problem,
that it's not something else!) should be treated as an environmental
stress factor
and adjustments should be made.

Potential Environmental Stress Factors
(health
and nutrition, loneliness
or boredom, personal
safety and security)
Chinchillas in captivity are entirely dependent on their chinparent
for everything, they have no freedom to run, forage or hide, no control
over the environment they exist in and this complete powerlessness
can be difficult and overwhelming for a small animal of prey. The
pet chinchilla's complete dependence on people for their care is what
makes the following list of potential stress factors so wide and varied.
The ability to make changes, to address an environmental stress
factor, IS completely within the chinparent's control, and it is their
duty to be observant and aware of how the chin is affected by his
environment so that appropriate changes can be made if the chin becomes
affected by a stress factor.
Once the attitude and behavior determinants
that directly influence a chin's ability to adjust and cope (temperament,
treatment, environment) have been assessed, it should be easier
to see what the potential environmental stress factor that is causing
the condition (fur-biting,
whitish eye
goop, etc.) might be. Bear in mind that what is a stress factor
for one chin may not be for another. For instance, a high-strung
or oversensitive chin may be more bothered by noise while sleeping
than other chins would be. Or, a group of chins that have never had
other chins close by and then find themselves in full view of chins
right next door (proximity is the issue, seeing other chins across
the room is not a problem but seeing them right next door often is)
may start having internal cagemate conflicts.
There may be more than one stress factor at work or it may take some
TIME and observation to pinpoint the real environmental stress factor,
then once pinpointed it may take some time afterward for the condition
(fur-biting, eye goop, etc.) to clear up. This list is NOT
all-inclusive, and as stated previously, the Environmental Stress
section takes a broad approach because the chinparent should apply
their analytical skills and intuition to troubleshoot within the context
of their particular situation:
HEALTH AND NUTRITION
An abrupt change in diet
Deprived of adequate rest (chins need some quiet solitude during
sleeping
hours)
Insufficient out-of-cage
exercise time
Deprived of dustbath
Feed or hay that is soiled or moldy
Cage too small and confining, a large
cage that allows for some running and jumping is a MUST!
Poor diet that causes malnutrition
(unsuitable pellets, i.e., those meant for other animals and not
chins; unhealthy or too many treats; no hay, etc.)
Unreliable availability of or inappropriate essential
items (pellets,
hay,
distilled
or filtered water, dustbath,
chew
toys, etc. Note that fresh, hay, pellets and water should ALWAYS
be available for consumption, do NOT ration pellets!)
LONELINESS OR BOREDOM
Grieving
for a cagemate that has departed.
Fur-biters
are often particularly intelligent and sensitive to an underactive
or overactive environment.
A single chin will require much more daily attention, interaction
and bonding
with their chinparent than those with a cagemate.
Quarantine,
sickness or recuperation should not consist of keeping the chin closed
off from any interaction or environmental stimulation. Even under
normal circumstances chinchillas need distractions in their environment
that keep them occupied when they're not actively engaged in interaction
and out-of-cage exercise
time. For this purpose a variety of chew
toys, a cage wheel
and TV
are all strongly advised, although in some cases a wheel may not be
feasible for a chin in recuperation.
Boredom is a very common
environmental stress factor because people often underestimate
how intelligent chins are and their need for sufficient interaction
and environmental stimulation.
Chins that are bored may chew on water bottles, their cage wheel or
bars or their hammock just for something to do.
PERSONAL SAFETY AND SECURITY
Temperature
too hot and/or humid
A big change, like a new pet (dog, cat, etc.) in the household,
moving to another city or state, getting re-homed
Too frequent or improper handling
Not being reassured upon arrival, see Initiating
Bonding, A Hands-On Approach
Not enough hideaways
(tube, hammock,
house- no
plastic- and one hideaway for each cohabitating chin can prevent
cagemate conflicts)
Fear of other household pets
(owls and foxes prey on chinchillas in the wild) or visiting
strangers
Using introduction methods that jeapordize
the chin's safety or violate their territorial
nature
Territory not secured (cage fully exposed to the epicenter of household
noise and chaos, full view of chins right next door that violates
territorialism,
marauding household pets)
Overcrowded conditions
Occassional or frequent neglect, abuse by people
Cagemate conflicts (dominating cagemate or insistent mate).
Weight loss can result when a dominated
cagemate spends his time defensively backed into a cage corner, afraid
to seek nourishment. See Maintaining
Group Compatibility: Preventing Conflicts, Causes
ANTI-SOCIAL BEHAVIOR

Facts
About Discipline and Behavioral
Rehabilitation for an understanding of how to address anti-social
behavior directed at people. See Maintaining
Group Compatibility for information about anti-social behavior
and chinchilla group dynamics.
We refer to the
behaviors described in this article as anti-social because they're
chiefly used to repel people or other chins, and sometimes other household
pets. By nature chinchillas are gentle and friendly, this has been
noted historically by those who hunted them for the fur trade, by
those who have studied them in the wild (these wild chinchilla
photos
speak volumes to that effect), and by those who own or breed them
today in captivity for pets. Chinchillas are herbivorous prey animals,
they aren't naturally aggressive or confrontational but they can rise
to the occassion if sufficiently stressed or frightened, and that's
when anti-social (defensive) behaviors emerge.
Anti-social behavior can appear to be offensive in intent but it is
in fact defensive. In our
experience working with hundreds of chinchillas from all backgrounds
since 1997, we have never met a "mean" chinchilla, there
is ALWAYS a reason for the anti-social behavior, a past or present
provocation. For instance, a chinchilla with past negative experiences
with people (neglect, abuse, being subjected to environmental stress)
or other chinchillas (being the victim of anti-social behavior)
may generalize from that past experience so that sometime in
the future when he feels confronted by another person or chinchilla,
he'll act out preemptively with anti-social (defensive) behavior.
It will appear that there was no provocation, but there was, just
not immediately preceding.
Anti-social
behavior is usually learned as a result of bad past experiences with
other chins, but sometimes this behavior is instinctual to a high-strung
or oversensitive chin. A chin cannot "unlearn" anti-social
behavior, but it can be successfully addressed through behavioral
rehabilitation or by using time-outs in an introductory
session. Anti-social behavior isn't always rooted in the past, though,
sometimes it's the result of a problem in the present, like an evironmental
stress factor
or the chin may be stressed due to recovering from a recent operation,
illness or injury, especially if not on pain medication. As the section
on Environmental
Stress relates, some chins are more temperamentally sensitive
to stress than others.
We define chinchilla anti-social behavior as any of the following:
dominance
mounting (it is instinctual for males to want to establish
dominance or rank but it becomes problematic when carried to the point
where there is persistent or aggressive mounting), biting, urine-spraying,
rearing up and chattering teeth, hostile pursuit, cornering and causing
fur
slip/ fur-pulling. Fighting itself may be injurious
(involves biting) or non-injurious (involves a combination
of the other, less severe behaviors).
It is also worth noting that when afraid, a chinchilla may release
an odor from his anal gland, which is "a scent gland located
in the opening of the anus" (ref-
Lioncrusher's Domain). The odor isn't particularly pungent but
it is definitely noticeable within a range of about 2-3', and has
been described as the smell of "burnt almonds." We jokingly
refer to this as "mad chin farts." This is one of many "warnings"
that a chin may give leading up to biting or urine-spraying, in fact
most of the anti-social behaviors are signs pointing to the possible
or eventual deployment of those two ultimate defenses.
Dominance Mounting occurs between chins and is covered in a
different section.

Biting
In the years that we've
worked with hundreds of chins, including unsocialized ranchies
and rescue chins from neglect and abuse situations, we've met fewer
than a half dozen chins that were true biters, that is, that REALLY
bit and pierced skin rather than just nibbled or gave a pressure bite.
There are three types of "biting": nibbles, pressure biting
and biting itself, and pressure biting (in an urgency context)
and nibbles aren't actually biting or anti-social, they're part of
normal chinchilla communication and are just described here alongside
biting for comparitive purposes:
1) Nibbling is not anti-social behavior, it's a normal, non-offensive
mode of communication
and should not be reacted to adversely. Nibbling can involve light
or firm contact, but it's not insistent to the point of almost piercing
skin, and it's done in a positive, amicable context. Chins nibble
each other while grooming to demonstrate acceptance and affection
and they may do the same with their chinparent, especially during
chin
scratches. Kits will nibble just as a baby explores his environment
by putting things in his mouth, all you need to do if the nibbling
becomes a bit too rough is to give a simple admonishment like, "gentle,
honey, gentle" and pull your hand back a little as a deterrent.
2) Pressure biting is definitely firm and insistent contact,
but unlike with an actual bite, the skin isn't pierced. Pressure bites
can happen in one of two situational contexts:
A) When a chin is expressing urgency: Like nibbling, pressure biting
(in the context of urgency) is not an anti-social behavior,
it's a normal, non-offensive mode of communication.
When a chin needs to urinate, wants down to play, to go back to his
cage, etc., he may put his teeth carefully on your hand or around
your finger and squeeze firmly but without intent to harm, just to
impart a sense of real urgency. In this case, try to figure out what
the chin wants and comply, there is no need to discourage pressure
biting when done in this context, after all, how else is a chin supposed
to express urgency?
B) When a chin is expressing extreme stress or fear: In this context,
pressure biting becomes anti-social enough to warrant using the "No
Bite" technique immediately to discourage future attempts.
Pressure biting in the context of stress/ fear has the same motivation
and intent as a chinchilla attempting to give an actual bite, only
the chin doesn't pierce skin either because he realizes that people
really can feel it when he bites (some chins are very surprised
that their bite even registers with a human who is so much larger)
or because he's too timid or temperamentally mellow to persist with
breaking skin. A chin who uses pressure biting in this context may
need behavioral
rehabilitation, especially if he bites often or uses other anti-social
behaviors.
3) Biting itself indicates a chinchilla at his MOST stressed
or frightened, and this is anti-social behavior that will need to
be discouraged immediately with the "No
Bite" technique. Biters should be considered a candidate
for Behavioral
Rehabilitation. Chinchilla bites are usually deep and piercing
rather than wide and gouging. Biting directed at people is rare, but
biting is more common between chins. Fight wounds (with other chins)
should receive immediate treatment.
Grinding or baring of teeth is a typical forewarning to biting, Nebula
and Friends provides a good general guide to the warning
signs of biting.

Urine-Spraying
(single
female chin syndrome)
Males can spray urine but rarely do, it's almost exclusively
a female behavior and is especially common to females with a high-strung
or oversensitive temperament.
Such temperamentally "difficult" chins may take more time
to get to know, and may require more bonding
effort on your part, but in our opinion these are frequently the most
intelligent, fascinating and fun chins to know.
Urine-spraying occurs when a female rears up and expels a jet of urine,
which can easily reach up to a few feet in length. The chin may stand
on her hind legs for a moment and give a warning sound first in low
buzzing tones, but there isn't always forewarning. Be aware that larger
chins may have trouble projecting the urine and can end up with a
wet bottom that will need dried off with a cloth and the chin given
dustbath. The urine isn't harmful in any way, to people or other chins
(although a shot in the eye can cause an eye irritation),
but if you suspect that a female is going to spray urine anywhere
near your head, keep your mouth shut! A chin that urine-sprays often
should be considered a candidate for Behavioral
Rehabilitation.
When a chin gets urine-sprayed, providing the chinparent is privvy
to it, then he should receive a dustbath
right afterward so that he can keep clean; chins get very dismayed
if they're not able to clean up right after being urine-sprayed. If
the chin is very urine-sprayed he might smell and be sticky, and in
this case dustbath alone will not suffice. Wipe him down using a warm,
damp cloth in a draft-free room, then towel or blow dry him completely
before administering dustbath.
Some females that are high-strung or oversensitive can be rather quick
to resort to urine-spraying, going beyond just warding off a perceived
threat (person, other chin) to using it when a cagemate becomes
a nuisance or to repel another cagemate in order to get to something
first or to keep something for herself, like a treat or chew toy.
Females that are near or in their estrus
cycle (think "PMS"!) are sometimes more easily provoked
and will spray urine accordingly.
Urine-spraying is also used by females as a way of "training"
their mate (to let ladies go first, to be a better guardian, etc.).
A male that runs over to his female when he should be taking a stand
to ensure she feels safe or doesn't get caught is sometimes deflected
with a reprimanding jet of urine; when people say that females "rule
the roost" in an M/F chinchilla pairing, this type of "training"
is one aspect of that. Some males try urine-spraying after being on
the receiving end of it with their females, but this isn't necessarily
a learned behavior.
"SINGLE FEMALE CHIN SYNDROME"
Urine-spraying towards people often results from being exposed
to a chaotic household or from other environmental stresses.
This is especially true in the case of a female housed alone who must
do all her own guarding, and who consequently tends to become paranoid
and develop stress-related behavioral problems, especially frequent
urine-spraying or other hostile displays (even biting), as
a result. We've seen
this frequently in the course of our rescue work, owners dropping
off their "impossible" single female chins, and other rescuers
have corroborated our observation. Eventually we had to to give this
phenomenon a name, something dark and ominous sounding... "Single
Female Chin Syndrome."
Chinchillas "stand guard" for each other when in groups
(two or more), this occurs mainly during sleeping hours or
when something stressful is going on (moving, travelling, strangers
in the house, etc.). Posture or position in the cage usually reveals
who is on "guard duty," in this
photo the chin in the protective posture is guarding. When two
chins are resting side by side, they may both be on guard duty. Chinchilla
males usually assume the guardian role in M/F cagemate situations,
in M/M or F/F situations they may take turns or one chin may prefer
to do most of the guarding.

Because males are more instinctually equipped for the protective or
guardian role, and because a female caged alone has no one else to
even share guard duty with, she is at a particular disadvantage and
may feel very vulnerable and stressed because she must overcompensate
to fill the guardian role. The SFC has to be "on" all the
time in order to do all her own guarding. Consequently, this can make
some oversensitive or high-strung
SFC's very defensive and prone to anti-social behaviors such as urine-spraying.
Not all SFC's have SFCS, but for those who do the best (non-reproductive)
solution is to get the SFC a female companion.

Rearing Up and Chattering Teeth
These two behaviors often occur together, but won't necessarily.
A chin that rears up is getting into position to potentially spray
urine and a chin that is chattering his teeth may potentially bite,
especially if the chattering becomes more like a grinding sound and
the chin is baring his teeth. Often when these behaviors are used
together it's because a chin feels trapped or cornered and he feels
compelled to pull himself up high and put on an intimidating act as
a last ditch effort to ward off the person or chin that he feels threatened
by. For instance, if a cagemate is being subjected to occassional
dominance mounting
and he's had enough of that, he may rear up and chatter with his teeth
in a warning manner to reject the antagonizer's advances. Chinchillas
also make a number of gruffing and barking sounds which are part of
their natural communication and which are often NOT used in the context
of anti-social behavior, see: Communication.
There is also a "pshaw" swipe that sometimes occurs when
chins are reared up and facing each other. It can happen when the
situation seems at a standstill, or when one chin is testing the other
to see if he really wants to continue the confrontation. The "pshaw"
swipe is the act of one chin swiping his paw across the face of the
other in a leisurely manner, sometimes getting it into the other chin's
mouth, but we've never seen the opposing chin take advantage of this
opportunity to try and bite during a "pshaw" gesture. The
results vary, perhaps the "pshaw" swipe is only meant to
break the tension, because afterward the chins may calm down or press
into more heated conflict.
Hostilely Pursuing, Cornering and Causing
Fur-Slip/ Fur-Pulling
Hostile pursuit occurs between chins, and this is almost always
bad news, because a chin who is hostilely pursues is very apt to bite
and that's why fur-slip occurs, because fur is pulled (released
by fur-slipping)
from the victim. Hostile pursuit is NOT the same as when a chin runs
about his cage for recreation and fun, it's only hostile pursuit when
there is one chin who pursues and another chin who flees. It is important
to pay attention when the sounds of vigorous running occur, because
when a chin is hostilely pursued within the limits of his cage, things
can turn deadly, see: Maintaining
Group Compatibility. The
aftermath of hostile pursuit is sometimes evident by tufts of slipped
fur lying about.

FACTS ABOUT DISCIPLINE
Also
see: General Characteristics
of Behavior
and Communication,
and Relating
to Your Chinchilla
Chinchillas do NOT respond to negative
chastising, i.e., physical (corporal)
punishment- hitting, smacking or flicking which can easily lead to
wounds
and abscessing-
or reprimands by shouting or similar displays of anger. Such
"discipline" is neither suitable nor effective in relating
to chinchillas, it will have the opposite desired effect. Because
chinchilla anti-social behavior directed at people is defensive in
nature and most often rooted in fear, frustration or stress,
when the chin receives a hostile reaction to his attempt to communicate
these feelings it justifies his need for a stronger defense and the
behavior will worsen, even escalate. Also, never blow on your chin's
face as a form of "punishment." According to our exotics
specialist vet,
chinchillas can catch a virus from people, such as cold or flu.
A chin that bites
or sprays urine may appear to be "vicious," may
seem to be offensive and hostile, but in reality the anti-social
behavior communicates the chinchilla's intense feelings of vulnerability,
demonstrates that he's feeling defensive for some underlying reason
that needs to be pinpointed and resolved in order for the anti-social
behavior to stop. When the chinparent addresses the underlying motivation
for the anti-social behavior, the chin will finally be able to feel
reassured
that he is now in good hands, relieved
of what's troubling him and secure
in his environment.
Chinchillas will only reform anti-social
behaviors when you use a positive approach as
opposed to a punishing approach, (see: Behavioral
Rehabilitation) and that requires maturity, love and PATIENCE
but the results can be truly miraculous! As long as you've always
given positive attention and positive reinforcement when they're good,
then warning them about something they shouldn't get into or saying
"no" in a serious but not intimidating way when they're
misbehaving will not be taken adversely. If you find yourself saying
"no" all the time then chances are you probably need to
make an adjustment, like do a better job chin-proofing
so your chin isn't tempted by hazards that require constant verbal
warnings; that's destructive to bonding
and unfair to the chin who should be free to explore in a safe environment.
Some chinchillas are gruff,
moody characters that are very vocal in their attitude. In our
experience, these chins are always the most interesting personalities,
and ultimately the most soft-hearted, likeable and misunderstood.
Our Sherlock was a good example of this. He was a neutered male
with a strong territorial
instinct and tender devotion to his three quite high-strung females.
Even after his death, an apparent heart attack, they were still a
perfectly harmonious group as a direct result of his influence and
uniting leadership. When one of the chinparents would approach the
cage door, he would dutifully come forward to assess the situation,
and gruff if one of his girls moved ahead of him since that overstepped
his authority. 
When we handed out treats during out-of-cage exercise time he was
happy to let his women go first, but if the cage door was opened,
that was Sherlock's cue! He'd rush up, gruff... and then turn and
run like heck! It was absolutely hilarious, his instinct leading him
to demonstrate verility and devotion to "the herd" in that
obligatory manner. The girls, of course, were always genuinely impressed
by this display. They'd demonstrate their respect for his leadership
by standing back in awe of Sherlock's manly "ferocity."
So what of Sherlock's gruffing, was that "vicious" behavior?
No. Because he was a cuddly sweetheart with us the rest of the time
we knew this was just an act and respected it because it kept him
happy and maintained harmony in his group. In fact, we would support
harmony in that group by acknowledging Sherlock's gruffing with praise
for his noble leadership. When he'd come back after the initial display
of ferocity, we'd tell him what a good boy he was for "defending"
his ladies and then offer a hand, palms up, for him to sniff and approve
of before we would enter his domain to clean up, give them food or
hay, or a scratch behind the ears or under the chin.
For every cage of more than one chin (same or opposite sex)
there will always be a more dominant chin who behaves similarly
to Sherlock. That's the "guardian" chin. If you acknowledge
and respect his authority then you are reinforcing the group bond,
the security and happiness of the group as a whole. As long as you
know the guardian is only gruffing for role playing or from a feisty
personality and is not afraid, frustrated or stressed
by anything in his environment, then it's ok to be affirming when
he gruffs. Tell him he's a good boy and offer your hand palms-up,
and honestly, he'll sit back and look so content, so pleased to be
understood and loved!

BEHAVIORAL REHABILITATION:
ADDRESSING BITING AND URINE-SPRAYING

Environmental
Stress, Anti-Social
Behavior, and Facts
About Discipline (the three preceding articles on this page)
Behavioral rehabilitation (BR)
can begin once it has been ascertained that the chin's anti-social
behavior is not caused by and will not discontinue by adjusting
potential stress
factors in the environment. BR is often necessary with chins that
have experienced past neglect, abuse or abandonment by people. BR
can also help soothe some chinchillas that are just naturally high-strung
(should be regarded as NFB)
or oversensitive.
Firstly, remember that owning a chinchilla requires maturity of
character: NEVER display temper, do NOT get loud or move in a loud
or boisterous manner around a chin that's already terrified (anti-social
behaviors are actually defensive). Chins are highly intelligent,
if you act consistently they may come to understand what you mean
but they don't speak fluent English or read minds- don't expect them
to. BE CALM, BE PATIENT.
Remember, with chinchillas their anti-social behavior is caused by
fear and bringing in corporal punishment compounds the fear. It'll
take maturity and unselfish compassion on your part to look past the
behavior and realize that this little animal is just scared silly
and that no matter how intimidating they manage to appear, they're
not really "bad, psycho, vicious."
The only way to address anti-social behavior
that can't be resolved by addressing an environmental stress
factor is to love them out of it, using empathy, gentleness,
calming reassurance, and persistent affection- NO corporal punishment.
Depending on the chin and their circumstances it can take time, but
BR does work because calming the fear will silence the anti-social
behavior.

Behavioral rehabilitation
can actually start as soon as you meet your chin, it can
become part of the bonding
process that you share: Do this every day, no more
than twice a day, for at least ten minutes at a time during
the evening, the chin's natural waking hours:
| 1)
|
If the chin
is biting, start by handling him carefully, needless to
say, don't put yourself in a position to get bit, wear
thick cloth gloves for now.
Female chins that have lived singly for awhile before
being rescue/ re-homed
are especially likely to spray
urine when relocated. Before picking up a chin who sprays
(males can but rarely, this is primarily a female defensive
behavior), have ready a container of Baby
Cornstarch Powder (no Baby Powder, nothing
containing talc!)
that can be purchased from the grocery store baby section.
When the female rears up to spray, squirt the cornstarch
at her lower extremities, it may take a couple squirts
and you need to take aim at the chin's LOWER half only,
DON'T get the powder in her nose or eyes. Eye irritants
can be flushed out using Natural Tears, nothing else unless
vet prescribed.
Scoop the chin up gently with both hands and hold him/her
on your lap, in a quiet place away from noise and distractions.
|
| 2) |
While holding
the chin, kiss (dry kisses!) his tummy and toes
(just in case he's worried, this demonstrates that
you won't eat him) and then rub his tummy, under the
chin, behind the ears or on the forehead; find what he
likes best and do that most. Then speak softly, soothingly,
things like "good boy/ girl, good -name-, good -name-"
and "good boy/ girl, you're my little angel, I love you."
Use loving praise and sweet talk in a reassuring tone,
quiet the fears, calm the anxiety and keep crooning in
a loving way. Remember, this will not be perceived by
the chin as "rewarding" the anti-social
behavior, it's resolving their fear and replacing it with
trust, security and love.
|
| 3) |
Continue holding,
massaging and soothing the chin every day for at least
ten minutes at a time, until you feel confident that
the biting chin is relaxed enough to be picked up without
gloves, and the urine-spraying chin has ceased that defensive
behavior.
Then work up to the point where you can kiss the biting
chin on the cheek or forehead and he wouldn't even think
of biting you, and the urine-spraying chin should reach
a point where she no longer backs into a corner and rears
up, threatening to spray.
|
| 4) |
Make out-of-cage
exercise time an extension of the BR time and then
let the chin approach you. You should move slowly around
him, allowing him to take the initiative- see Playtime
Bonding.
|
| 5)
|
Give him TV
during his waking hours! This is a tremendous rehabilitative
tool for chins with behavioral issues, see The
TV Attraction.
|
| 6) |
Provide a
setup that is relatively quiet and peaceful (away from
prying pets, excessive traffic) and cover his cage
with a sheet (as described on Routines)
for privacy and security. You can choose to play some
classical music very softly in the background.
The BR process works, but it takes time, sometimes a few
days, sometimes a few weeks or more than a month- it depends
on the type of anti-social
behavior, what caused it and the personality of the chin.
Gradually, your persistent love and patience WILL win
him over and in time he'll relax, become calmer, curious
and receptive to you as his fear and apprehensions fade
away.
|
|
 |
Once the anti-social
behavior is gone and you've built a positive rapport, established
trust and your chin is secure in the knowledge that he is safe
and loved, then the only deterrent or reprimand you should need
in the future is a change of tone in your voice and a "no"
spoken firmly, not loudly or in a frightening manner.
|
 |
There are exceptions
to every rule, and the "No Bite" technique
is intended for that. If your chin has been through BR or has
been taught as a youngster not to bite
(i.e., when you know that he knows the difference between
nibbling and biting) but bites anyway, then use this technique.
Again, the No Bite technique is only useful once a bond of
trust and affection has been established, when the chin
understands that you have his best interests at heart and feels
secure and cared for in his environment- otherwise, this
will make matters worse!!
| 1) |
Catch and hold
him securely, putting your thumb on one side of his mouth
and your index finger on the other side of his mouth,
far back enough not to get bit but forward enough to be
able to GENTLY squeeze just enough so that he's making
a puckered expression similar to what a chin looks
like when his incisors are checked for dental health.
|
| 2) |
Say in a low
and firm tone, "no bite, no." DO NOT shout. Single syllables
are best to aid remembering.
|
| 3) |
DO NOT hold
his face in this position for more than a few seconds
because chins breathe through their nose and this could
make it a bit difficult for him to breathe.
|
| 4) |
They understand
by association- you're holding his mouth so that he can't
bite, while saying "no bite" Once a chin has been reprimanded
with the No Bite technique once, simply saying "no bite"
in a calm and firm tone after that should be a sufficient
deterrent, we rarely have to use the No Bite technique
more than once or twice. |
