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 most of the cats in American homes and shelters, and names like tabby, tuxedo or calico describe coats, not breeds. Most are medium-sized, about 6 to 14 pounds, sturdy and adaptable.
Size, energy and personality vary widely, from lap-loving homebodies to busy explorers. What you see in person, a cat's age, history and behavior, predicts far more than coat color does. Match energy, sociability and grooming needs to your household: a short coat needs little brushing, while a long coat needs regular combing to prevent mats. Most live 12 to 18 years, so adoption is a long commitment.
