The correct term for referring to a group of cats is 'clowder.' Interestingly, there are also two other valid ways to refer to a group of cats, other than just saying "group of cats" or "cats." Those other two terms are 'clutter' and 'glaring.'

In addition to this, if one wants to refer to a group of wild cats, the correct terms are 'dowt' and 'destruction.' A male cat, when neutered, is called a "gib," when not, is called a "tom." Female cats are known as "molly."

The word "cat" itself derives from the Old English "catt." Catt has its source in the Late Latin "catus," meaning: "domestic cat." This Late Latin word probably derives from an Afro-Asiatic word: "kaddîska," meaning "wild cat."
