Domestic Medium Hair is a coat description rather than a breed. The label covers mixed-ancestry house cats whose fur falls between short and long: fuller than a shorthair's, 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, and most are medium-sized, weighing roughly 6 to 14 pounds.
Because ancestry is mixed, size, personality and health follow the cat, not a breed standard. Many are adaptable and affectionate, and most live 12 to 18 years indoors. In a city where many people live in rowhouses and apartments, that sturdy build suits indoor life well. Plan on weekly brushing, more in spring and fall, and let meeting a cat in person guide your choice.
