Tuxedo describes a coat, not a breed: a bicolor cat, usually black and white, with a white chest like a shirtfront and often white paws or chin. Grey-and-white tuxedos exist too. The pattern comes from white spotting in the KIT gene, and because it isn't sex-linked, males and females are about equally common.
Most tuxedos are domestic shorthairs, though the pattern also appears in breeds like the Maine Coon and British Shorthair. Color doesn't set personality, so Morgantown adopters will meet every temperament and energy level. Coat length, age and history shape daily care far more than the markings do. Spend time with a cat before choosing, and plan for moderate shedding and a weekly brushing.
