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, so a calico's size, fur length and build depend on her ancestry. Most weigh somewhere between 6 and 12 pounds and live 12 to 18 years with good care.
Because most calicos are domestic shorthairs, their needs look like those of any house cat: steady meals, play, dental care and a safe indoor home. Folklore gives calicos a feisty streak, but research hasn't shown that color predicts personality. Spending time with a cat and seeing how she handles people and other pets is a far better guide than her patches.
