What Is A Colony Of Cats?
A cat colony typically comprises a group of usually related female cats along with their kittens, with its size influenced by the availability of food and resources. Adult male cats generally do not reside within these colonies, although amicable interactions between females and males can occur, particularly when there is a sense of familiarity.
