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 names like tabby, tuxedo or calico describe coats rather than breeds. Most weigh 6 to 14 pounds, and indoor cats often live well into their teens.
Personality and energy vary a lot, from relaxed homebodies to busy explorers, and a cat's age, history and behavior say far more than looks do. Shedding is usually moderate, with longhaired cats needing more brushing to prevent mats. That means you can choose a cat that fits your schedule and space, whether that's a calm senior or a playful young cat.
