A mixed breed cat is a cat of no particular breed, usually a domestic shorthair, medium-hair or longhair with mixed or unknown ancestry. These cats make up the large majority of cats in American homes and shelters, and they come in every coat length, color and pattern. Names like tabby, tuxedo and calico describe coats, not breeds.
Size, energy and personality vary widely, from lap-loving homebodies to busy explorers. Most weigh 6 to 14 pounds and are sturdy and adaptable, and a cat's age and observed behavior say far more than looks do. In Tucson, that adaptability helps: a cat with a cool, quiet home base handles desert summers indoors, while grooming needs follow coat length.
