A female cat is called a queen. Male cats, on the other hand, are called toms. Cats are generally associated with the female of the species. When you call a woman ``catty'', for example, what you are implying is that she is very unpleasant and usually has a lot of nasty things to say about others.
Before breeding your cat, learn what is involved in mating, reproducing and delivering healthy kittens. Sometimes, breeding isn't a good idea. Puberty in a male cat, called a tom cat, sets in at 6 to 8 months of age when he is able to fertilize a female cat. The male's reproductive life can last 14 years or more.
