Calico cat is an American name for cats with three colors. Outside of North America they are usually called tortoiseshell cats or 'tortie-and-white'.[1] A calico cat has a coat of orange or brown and black spots on a white background.[2] It is not a breed of cat.[3]
Nearly all calico cats are female.[4] There are male calico cats, but they are very rare. Only one of every 3000 calico cats are male.[5]
