A mixed breed cat is a cat of no particular breed, usually a domestic shorthair, medium-hair or longhair whose ancestry is mixed or unknown. These cats make up the large majority of cats in American homes and shelters. They come in every coat length, color and pattern, and names like tabby, tuxedo or calico describe their coats rather than a breed.
With such a broad gene pool, size, energy and personality vary widely, from lap-loving homebodies to busy explorers. Most are medium-sized, sturdy and adaptable, and a cat's age, history and observed behavior predict far more than looks do. Adopters can match energy, sociability and grooming needs to their household rather than relying on breed labels.
