 “Calico” refers only to a color pattern on the fur, from colorful printed Calico fabric, not to a cat breed or any reference to any other traits, such as its eyes.Among the breeds whose formal standards allow calico coloration are the Manx cat, American Shorthair, Maine Coon, British Shorthair, Persian cat, Arabian Mau, Japanese Bobtail, Exotic Shorthair, Siberian, Turkish Van, Turkish Angora and Norwegian Forest cat.Because genetic determination of coat colors in calico cats is linked to the X chromosome, calicos are nearly always female, with one color linked to the maternal X chromosome and a second color linked to the paternal X chromosome.
