A male cat is called a tom or a tomcat. If he is neutered, he is called a gib. If the male is kept for breeding purposes, he may be referred to as a sire.
A female cat that is able to breed is called a queen. If she is spayed or too immature to get impregnated, she is a molly. Groups of cats are sometimes called "clowders." The offspring of a tomcat and a queen are known as kittens.
Cats were domesticated as early as 7500 B.C. and can be found in all parts of the world where there are people.
