A mixed breed cat is a cat of no particular breed, usually a domestic shorthair, medium-hair or longhair with mixed or unknown ancestry. They make up most of the cats in American homes, and they come in every coat length, color and pattern. Tabby, tuxedo and calico describe a coat, not a breed.
Size, energy and personality vary widely, from lap-loving homebodies to busy explorers. Most weigh 6 to 14 pounds and live 12 to 18 years, often into their teens indoors. In Colorado Springs, where winters are cold and summer afternoons bring storms, an indoor cat does well, and an adult's observed behavior tells you more than its looks. Match energy, sociability and grooming needs to your household.
