Cats are territorial in nature but the domesticated cats
consider this differently to that of the wildcat. There are reasons
why a cat is territorial.
The first reason is to ensure that it will have
and shelter for its requirements. As the domesticated cat gets that
food and shelter from its owner it does not need to concern itself
with becoming territorial for that reason.
The second reason why cats are territorial is because in the wild
they will be vying for the female when they are in season. Once
again this is eliminated in most cases as the domesticated household
cat has been neutered
and a desire to be territorial for this reason is no longer present.
In addition to this, the fact that the domesticated cat generally
lives in areas where there are many more cats in close proximity
to one another, thereby reducing the reality of any cats
having the ability to dominate any area much greater than their
own backyard, this is no longer a realistic concern.
This has often led to a somewhat more social behavior with domesticated
cats where they can sometimes welcome neighbor's cats or at the
very least put up with the fact that other cats will sometimes wander
through their territory. The fact that they are comfortable with
the property, and realize that the security, food and shelter requirements
are being met without any action required on their part means they
no longer feel the need to be territorial.
Fortunately this makes life a lot easier for cat owners living
close to one another, as it reduces the incidence of cat fights
and also the unwanted habit of cats
leaving their scent on other people's properties. It certainly makes
for a lot happier environment than if our cats still possessed the
behavior that is natural to them in the wild.
