They are called a clowder or a glaring. —John Ciribassi, DVM, DACVB
A group of cats is a clowder. A group of related kittens is a litter. A few litters are a kindle. —Elizabeth Colleran, DVM, DAVBP (feline practice)
A group of cats is called a “clowder.” Clowder originates in Middle English from the term “clotter,” which meant, “to huddle together.” It also has roots in “clutter” which is what my clowder creates in my house.
