Can you guess the sex of this cat. Is this a Tom or Queen or third generation. This beautiful picture is the real mystery in term of sex . A group of cats is mentioned as a "clowder", a male cat is named a "tom" (or a "gib", if neutered), and a female is named a "molly" or "queen". The male progenitor of a cat, especially a pedigreed cat, is its "sire", and its female progenitor is its "dam". An immature cat is named a "kitten". In medieval Britain, the word kitten was interchangeable with the word catling.
