Domestic Medium Hair is a coat description rather than a breed. It covers mixed-ancestry cats whose fur falls between short and long, with a fuller tail, tufts between the toes and a soft undercoat, but none of the heavy ruff of a true longhair. They come in every color and pattern, from tabby and tuxedo to calico and solid black.
Because their ancestry is mixed, size, personality and health vary from cat to cat. Most weigh 6 to 14 pounds, are sturdy and live 12 to 18 years. Plan on brushing a few times a week, and more in spring and fall when the undercoat sheds. Let the cat's own behavior, not its coat, guide the match.
