Domestic Medium Hair is a coat description rather than a breed. It covers mixed-ancestry cats whose fur is fuller than a shorthair's but without a heavy ruff, often with a plumed tail, tufts between the toes and a soft undercoat. They come in every color and pattern, from tabby and tuxedo to calico and solid black.
Size, personality and health follow each cat's ancestry and history instead of a breed standard. Most are medium-sized and sturdy, and many live well into their teens. In Kingston, where winters are long and cold, that soft undercoat keeps a cat comfortable by a drafty window, though it also means more shed fur on couches and sweaters. Meeting the cat is the best way to judge temperament.
