Kittypets are soft-muscled cats that live with, and are pampered by their twolegs. They are very plump and well fed because twolegs feed them several times daily with dry, tasteless pellets that look like rabbit droppings, and soft slop, according to clan cats. They usually know very little about hunting and fighting, although there have been a few notable exceptions. At a certain age, kittypets are usually taken to the vet, which also known as the cutter by clan cats, to get spayed or neutered.

The soft life of a kittypet is scorned by clan cats, and it is against the warrior code for them to become kittypets.
