Cat Help?

Is there a word for a young, unattached female cat? All I know is that
a breeding female is a "queen."

According to Wikipedia,

A group of cats is referred to as a "clowder", a male cat is called a "tom" (or a "gib", if neutered), and a female is called a "molly" or "queen". The male progenitor of a cat, especially a pedigreed cat, is its "sire", and its female progenitor is its "dam".

So I guess that means both breeding and youn cats would be the same. If they are below breeding age, I think they'd be a kitten.

Sorry I couldn't be of more help.
