What is a group of cats called?

A group of cats is referred to as a "clowder" or a "clutter" and also a "glaring",

If you want 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” or a "tomcat" An unaltered female is called a "queen" or a "molly" and a juvenile cat is referred to as a "kitten".

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”.
