Have you ever heard of a clowder? That’s the correct term for a group of cats. Also used are cluster, clutter, destruction of cats and pounce of cats.
Of course there’s a litter of kittens and a colony of feral cats. So where did the odd and not very flattering term clowder come from? It’s thought that it originated in the middle east in the late 1700s and it describes a clotted mass.
And did you know that a clowder or colony of cats will 
have a hierarchy—a cat that ranks higher in the colony (or household, even). How do you tell which cat that is? The one that is most often rubbed on by the other cats. The cats know which one is boss and they continually remind him of his hierarchy by rubbing against him. The more the cat (or human) is rubbed on by another cat, the higher in the hierarchy the cat (or human) ranks.
