Calico is a coat pattern, not a breed: white with patches of orange and black, or the softer cream and gray dilute version. Nearly all calicos are female because the orange and black color genes sit on the X chromosome, and most are domestic shorthairs of ordinary house-cat size, around 6 to 12 pounds.
Because the pattern says nothing about ancestry, a calico's energy, coat length and health follow the cat underneath. Expect moderate shedding, regular play and a lifespan of 12 to 18 years. In Chattanooga, that usually means an easygoing indoor companion who needs parasite prevention, a plan for storm season, and a little patience while a shy cat settles in.
