Domestic Medium Hair is a coat description, not a breed. It covers mixed-ancestry house cats whose fur falls between short and long: fuller than a shorthair, often with a plumed tail, tufts between the toes and a soft undercoat, but without a heavy ruff. They come in every color and pattern, from tabby and tuxedo to calico and solid black.
Size and personality vary from cat to cat, so meeting the cat tells you more than the label does. Most are sturdy, medium-sized and long-lived. Expect more brushing than a shorthair needs, particularly when the seasons change, and in Warren's cold winters a quick comb a few times a week keeps a thick undercoat from matting.
