Tuxedo describes a coat pattern, not a breed: a bicolor cat, usually black and white, with a white chest that looks like a shirtfront and often white paws, chin or a facial blaze. Grey-and-white Tuxedos exist too. The pattern comes from white spotting variation in the KIT gene, and because it isn't sex-linked, males and females are about equally common.
Most Tuxedo cats are domestic shorthairs, though the pattern also appears in breeds such as the Maine Coon, British Shorthair and Persian. Stories about Tuxedos being especially smart or bold are fun but unproven, since color doesn't set personality. Shedding is moderate, so expect regular brushing, and expect every age, size and energy level in Greenville.
