What
Captive Animals Need
When you visit a zoo, please give some thought to
the needs of the animals you see.
The information below can make you more informed
-
and hopefully, you too will become a
'friend of captive animals'.
Wild animals forced to live captive lives have very complex
needs. Food, water,
and protection from the elements are only the
start. Even with those three
basic needs taken care of, a captive
animal can still be driven mad from
stress and loneliness.
Researchers who study animals in their free, native habitats know
that many animal species
live in highly-developed social groups. These
social animals need each other's company, and
suffer emotionally when
forced to live alone. Social animals,
such as primates and wolves, are sometimes housed in
isolation in many privately-owned Ontario zoos, while some
normally
solitary animals are kept in groups. An animal that
would naturally live in a pack, herd, or other social
group
appears to suffer emotional distress when forced to live
alone.
Every effort should be made to avoid this.
Just as important, a naturally solitary animal should not be
forced
to share a cage with another animal.
For some species, there are provisions that zoo
keepers can make to ease
the stresses of captive life.
Animal Groupings - Animals
should be kept in numbers that meet their social and
behavioural needs.
For example, herd animals should be kept in herds and family animals
should be kept in family groups. Solitary animals should be allowed to
live alone. If a species
would typically live in a family or pack grouping of
several animals, then even a pair living
together can be inadequate. Though a pair would be better in most cases than a solitary
animal,
a more dominant animal may unduly harass its lone cage mate when it
does not
have a larger, more natural animal grouping to act as a
social buffer.
Enrichment - means
interesting activities that relieve boredom and stress. This is
essential as signs of mental distress are often observed in confined
animals that do not
have enough variety and activity in their day. The zoo keeper can provide 'enrichment'
through enclosure
structures, furnishings and play-objects that encourage natural
activities. Different objects that the animals can use as toys can be placed in
the
enclosure, and should be changed from time to time, to provide an
element of surprise
and variety. Animal-management practices, such as how food is presented, can also
provide
enrichment.
By providing play-objects (toys) and offering food
in interesting ways they help the animals cope with the stress of
captivity. These links show how enrichment is provided at two large zoos:
The Toronto Zoo: http://torontozoo.ca/meet_animals/enrichment/index.htm
The Honolulu Zoo: http://www.honoluluzoo.org/enrichment_activities.htm
Even smaller, privately-owned zoos can use enrichment techniques!
Without enrichment captive animals frequently experience a stress
response similar to
mental illness, which can cause animals to behave
abnormally: for example, adopting
repetitive, obsessive motions. These behaviours are called 'stereotypies' and
indicate that
an animal is in distress. 'Stereotypies' are
obsessive, repetitive movements that have no
natural purpose. Pacing, rocking, bar-biting, and self mutilation
through excessive
chewing, licking, self-biting or feather plucking are examples of 'stereotypies'.
Stress, frustration, and boredom are believed to be major causes of
this disturbed
behaviour. These behaviours are signs that the animal is
in distress. An animal that normally spends its day digging for food needs to be
provided with a similar activity in captivity.
For example, food can be 'hidden' in ways that this type of
animal would have to find
through digging. This type of animal should
not be housed on a cement or wire mesh floor,
but on wood chips or other
material that allows it to engage in its natural digging activity.
Many animals in captivity have nothing to do!
They are deprived of their natural activities like hunting,
foraging, pecking, digging
or climbing; and are not given replacement
activities. This lack of activity can result
in stress and depression,
which appear to be as emotionally painful for animals as
humans. For example: at one facility, beavers currently live in a
cement-lined pool,
deprived of opportunities to seek out food or
engage in dam building - activities that would
comprise a good portion
of each day in the wild. Wouldn't it be better animal management
(and more compassionate)
to provide these beavers with wood to allow them to engage in
natural
activities?
As Dr Georgia Mason from University of Oxford
speaking at the BA Festival of Science,
stated: "Animals kept in captivity exhibit stereotypic
behaviour that is fundamentally
similar to that seen in human conditions
of autism and schizophrenia..."
We need to ask ourselves: Is it appropriate to drive animals to emotional
states similar to mental illness for nothing more than an hour or two of
human entertainment?
Appropriate Enclosure Size -
Sufficient space to allow for normal movement
including
running, swimming or flying at natural speeds -
both
horizontally and vertically -as is natural for
the animal.
Substrates
- (the 'flooring' material beneath
the animal's feet.) Natural
materials that are
comfortable and allow natural behaviours, such
as
digging or pecking, should be used. Wire mesh
and concrete are easy to clean, but
uncomfortable for the
animal, and should be
avoided.
Shelter and Privacy
-
Structures, natural
features (shrubs, trees, logs) and other items
should provide comfortable shelter from
all weather conditions. These
features should also allow the animal to escape from public
view and, at
times, from their cage mates. The inability to find privacy when needed can
lead to chronic stress
for the animal.
Proper environmental conditions -
Temperature, humidity, ventilation, lighting and
cleanliness
appropriate to the type of animal. For instance: nocturnal animals should
not be displayed in
daylight-type lighting. Most animals in the wild would seek out both
sunshine and shade at
different times. This should be easy for us to understand, as we
humans also choose to
enjoy the warm sun at one time, but then seek a cool shade at
another. A proper animal enclosure would allow the animal to choose sun, shade
or shelter
as it wishes.
Nutritious food and sanitary water- This includes a varied diet, in sufficient quantity,
and
presented in a way that is natural for the specific animal species. A prepared
'chow' may provide the basic nutritional needs, but
should be supplemented with natural
foods, such as fruits, vegetables or
meat, as is appropriate for the animal. Many species
have complex (and expensive) nutritional needs
that make them unsuitable for
housing by small zoo owners or private
collectors.
Responsible choices should be made as to which animal
species can be housed and provided for properly. Unfortunately, some small zoo owners and collectors lack the
nutritional knowledge and/or finances to feed all animal species
adequately. For example: It is common practice for carnivores in smaller zoos to
be fed a diet consisting mainly of "spent hens" (egg-laying chickens
that can no longer lay enough eggs and so are disposed of). While this kind of diet will keep a carnivore alive, and is cheap for
the zoo owner, it is nutritionally deficient and does not provide enough
variety.
How the food is presented is also important. Food should be presented in a way that
does not encourage
aggression among cage-mates as they react to the stimulus of
the food
being offered. If more than one animal shares a cage, then food needs to be
given
in such a way as to minimize, 'feeding stress' or aggression
between the cage mates
as they compete for the food. If possible, aggressive cage mates should be fed in different areas
of the enclosure (this assumes the enclosure is big enough to allow
for sufficient
distance between the animals,) to reduce 'feeding
stress'.
It is essential to make sure that every
animal gets an
appropriate ration of food.
It is true that in the wild, a more aggressive or dominant
pack member may eat a larger portion of food. 
However, in the wild, the more submissive pack mate is also
free to roam and forage and may still be able to acquire more food
through stealth. Opportunities to forage do not exist in most small zoos. If food is only presented once or twice a day, and each
animal cannot be sure he or she will get an appropriate ration, then
stress and aggression are inevitable. Stress and aggression caused by improper feeding
methods add to the misery of a captive life that is poorly-managed. The fact that a small-zoo owner cannot afford to purchase appropriate
food for a particular species should not serve as an excuse to provide
an inadequate diet.
It is reasonable to expect that responsible zoo owners will keep only those
animals
that they can afford to feed and house properly.
Veterinary Care - Proper
care from a Veterinarian with knowledge about the various
species housed
at the facility is essential. It is a significant challenge for a Veterinarian
who usually treats
farm animals and pets - no matter how knowledgeable and caring that
doctor may be - to understand the needs of several extremely different
species. The
Veterinarian providing care will need to be willing to
consult with experts to seek the
needed information. It is the responsibility of zoo owners to house only those
animal species that they can provide with proper veterinary care. For instance, a
privately owned zoo may not have access to a
primate or 'big cat' specialist. This problem
demonstrates that housing a widevariety of
species in a smaller facility without the
financial resources of a
large, publicly-funded zoo can lead to unnecessary hardship for
some
of the animals.
Proper Record keeping and Licensing- These contribute to accountability on the part
of the zoo
keeper, and provide protection to the animals. If proper records must be
kept, then a sick or injured animal cannot
'just disappear'. Surely it is reasonable to expect
a zoo owner to
demonstrate that veterinary care is provided to sick animals when
needed.
Humane Zoo Management Involves Even More Considerations
Some Animal Species are more difficult to house adequately
than others. For
example: some animals are designed to move through many
square kilometres of their
home range each day. Life in a cage can never give these types of animals what a free
life
could, or come close enough to allow them a relatively
meaningful existence. If a
particular species cannot be housed in a smaller
facility in a humane way, then why
not forgo the keeping of that type of
animal for display?
If a handful of specific animal species are not
displayed at a zoo, this does not mean that families will stop coming. In fact, as people learn more about the needs of
animals, many families may come to appreciate that the facility they
visit has made humane and responsible choices.
As we learn more about animals, many well-meaning zoo keepers are
questioning what
types of animals can be housed in the zoo environment. We visitors to zoos should also
question what species can be housed
adequately without undue hardship to the animal.
Visitors to zoos can help animals by:
- only visiting zoos that house animals properly,
- avoiding any zoos that boast a wide selection
of different animals, but does not have sufficient space or
financial resources to provide properly for them,
- speaking to zoo-owners that are not housing animals
adequately and politely asking for improvements to be made.
Importance of Appropriate Animal
Groupings:
Attempting to keep a wide variety of animal types
often means the smaller zoo has only
one or two of a species that would
normally live in a family group, pack, or herd. Or,
sometimes the animal enclosures are too small and poorly
furnished in order for the zoo to
display a variety of
animals in a limited space. Wouldn't it be far better to keep a limited
number of species, and have enough space, money and expertise to provide
a high
quality of life for these animals? After all, they live captive lives to provide income and
entertainment. Surely we owe them more than mere survival in return.
The need for space affects specific animal species in
different ways. Kangaroos, for
instance, would normally range over
several kilometres of territory each day through
bounding hops, and
are not designed to move easily in closed areas. Several acres per
kangaroo would be needed to provide an
adequate life for an adult kangaroo - a
provision that is
impossible for most privately owned zoos to provide. Kangaroos are social
animals and should not be housed alone, and the
amount of space needed for several
kangaroos would be significant. It is
highly unlikely that any small facility can provide a
reasonable quality
of life for kangaroos.
There are no enclosure furnishings or pen designs
that can adequately
substitute the natural environment for this type of
animal.
Let's be honest... We will still live happy lives if we never see every animal
type up close. No child will grow up deprived because he or she did not
get to see an actual tiger or kangaroo.
Legislation is urgently needed to ensure that
captive animals are provided with
acceptable standards of care. Legislation to protect zoo and other captive
wildlife
should guarantee more than what is merely needed to sustain
life. Legislation
should also guarantee a reasonable measure of
physical, mental, and emotional
well-being to captive animals. Failure to provide for these needs leads to an
unacceptable degree of
suffering for these feeling, vulnerable creatures.
Passing laws to regulate zoos and wildlife exhibits
is not harmful to the zoo industry. On the contrary, proper legislation would allow
zoo keepers to benefit from improved research and study about the
needs of the animals that provide income for them.
All industries change and develop throughout
time, why not zoos? At one time restaurants were not regulated or inspected. Rules and
guidelines have improved the restaurant industry - not harmed it.
The current lack of legislation in Ontario (Canada) has led
to some deplorable
situations at many zoos across this
province. No responsible zoo owner need fear this
legislation,
as it has been demonstrated in other regions that these standards are
achievable. The purpose of this legislation is to help animals - not to hurt
businesses! The
research for this legislation already exists, so there is no need
to spend time and money on
'reinventing the wheel.'
Conclusion: It is an enormous task to properly provide for
captive, wild animals with their complex and varied needs.
Caring adequately for several species may be difficult for a
privately-owned facility without access to public funding. An owner of a private zoo or animal collection must make some
careful
and well-researched decisions in order to provide for animals in a
humane and
responsible way.
The responsible zoo owner needs to make very careful choices
about:
- which species, and
- how many different species can be adequately cared for on the property that is available.
It is very expensive to care properly for wild
captive animals. How much money is
available to the zoo owner must be
taken into consideration when choosing which
animal species will be
housed at the zoo.
We should admire private zoo owners who make the responsible choice to
house only those types of animals that they have
space, money and
expertise to provide for properly.
Wouldn't it be far more interesting to see an appropriate
grouping of animals interacting together, rather than one or
two lonely animals in a barren pen? Animals living in appropriate groupings and with sufficient
space and enclosure design would be able to
engage in play and natural activities with their fellow cage mates. Such groups could live in large enclosures with natural
grasses, bushes and trees, as well as constructed furnishings
(platforms and climbers) that mimic their natural
world. Visitors watching these animals would see the
animals natural
behaviour, which is surely more interesting than observing a bored
animal sleeping or a distressed animal pacing.
We are part of the problem if we spend our money at
facilities that do not provide adequate environments for
their animals. 
Let's all try to learn more - to do
better - to help captive animals.
