HISTORY
OF CATS
Domestication Of Cats
For the cat, as for other
domestic animals, the process of domestication occurred over a long
period of time. Wild cats would have become associated with humans
once humans stopped being hunter-gatherers and formed permanent
settlements where they farmed. Harvested grain would be stored in
grain stores which would attract mice and rats which would have
attracted wild cats. Human agriculturists would quickly see the
advantage of encouraging cats to help control the vermin, so a loose
but mutually beneficial association would have been forged.
When the process of domestication
started is unclear, estimates rely on archaeological discoveries
of cat remains that can be shown to be closely associated with humans.
Although various remains have been found in Egyptian archaeological
sites dating to 6700BC, there is no firm evidence to suggest that
these were domesticated cats, in fact they are more likely to have
been wild cats. If finding a cat skeleton buried with a person is
evidence of domestication then this is first seen about 5000BC in
Egypt. However it was not until 2500BC that cats were first depicted
in Egyptian tomb art. Cat remains from Egypt around 2000BC could
well be from a domestic variety and paintings and inscriptions from
the same period portray cats in situations that suggest that they
were domesticated. From this time on there is plenty of evidence
to show that cats became well established in Egyptian homes.
It has been suggested that
this process of domestication of the African wild cat that happened
in Egypt around 2000BC took place because of a genetic change. The
basis for this reasoning is that domestic cats have kittens that
are tame while wild cats have kittens that are aggressive. Wild
cat kittens can be tamed but they are not born tame. Therefore the
reasoning goes that there must have been a genetic change to make
domestic kittens inherently tame. This genetic change resulted in
cats loosing their wild temperament and gaining a domestic temperament.
This genetic change that results in tame kittens also seems to prevent
the development of some adult behaviour patterns that are seen in
wild cats. Domestic cats retain juvenile behaviour patterns and
don't progress to the adult behaviour seen in wild cats. This retention
of juvenile behaviour is known as neotony. Adult wild cats are solitary
but a close family group is formed when a female gives birth to
and rears her kittens. As the wild cat kittens mature they again
become loners. This is not the case with domestic cats which retain
juvenile behaviour and remain in groups. Even domestic cats which
become feral tend to stay together in colonies.
This genetic change could
have come about by a domestication mutation or selective breeding
by humans. People would choose to keep and breed the cats that were
easily managed. Those displaying neotony or juvenile characteristics
were more family oriented and less independent than adult cats and
were therefore more suited to life within a human family. This process
of domestication is the same that occurred with the dog.
Despite domestication a cats
wild temperament is just below the surface and not all cats show
the same degree of tameness. There is a wide range of temperaments
within the domestic cat population, some cats are extremely tame
others have a definite wild streak. Lack of aggression in domestic
cats needs to be reinforced by human contact form an early age.
If not some of the wild cats temperament starts to reappear. For
example, kittens born to a domestic cat that has become feral are
distrustful of humans and have to be subjected to basic taming in
order to adapt to living in a human home.
