Calico describes a coat, not a breed: white with patches of black and orange, or soft gray and cream in the dilute version. The pattern appears in domestic shorthairs and longhairs and in several pedigreed breeds, and nearly all calicos are female because the orange and black color genes sit on the X chromosome.
Because most calicos are domestic shorthairs, their size and care look like those of any house cat. Most weigh 6 to 12 pounds and live 12 to 18 years indoors. Shedding is moderate, so weekly brushing helps, and a longhaired mix needs it more often. In St. Cloud, where cats spend much of the year inside, personality and energy level matter more than patches when you're choosing a cat.
