Calico describes a coat, not a breed: white with patches of orange and black, or gray and cream in the dilute version. Nearly all calicos are female, and most you'll meet in Oklahoma City are domestic shorthairs, with the occasional longhaired mix. Adults usually weigh 6 to 12 pounds and live 12 to 18 years, so adopting one is a commitment of well over a decade.
Because the pattern comes from genetics rather than a breed standard, temperament, coat and care needs differ from cat to cat. Shedding is moderate, and a weekly brush handles most coats. In OKC, daily care comes down to a safe indoor home, steady play, and a plan for storms and cold snaps. Spend time with a cat before deciding, since her behavior says more than her patches.
