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.
Female cats or queens go through four hormonal cycles (male cats are called toms) which dictate cat mating behavior. The entire estrous or head cycle lasts 10 to 14 days. When your queen is ready to mate she will go through a series of flirting behaviors designed to attract a male in the way she acts and sounds.
