Domestic Medium Hair is a coat description rather than a breed. The label covers mixed-ancestry cats with a fuller coat than a shorthair, often with a plumed tail, tufts between the toes and a soft undercoat, in every color and pattern. Most weigh 6 to 14 pounds and live 12 to 18 years indoors.
Because the ancestry is mixed, personality and health follow the cat, not a breed standard. Some are lap cats and others are bold and chatty, so meeting a cat tells you more than its coat does. Regular brushing keeps the fur from matting and cuts down on hairballs, which matters most when indoor heating dries the coat in winter. Kittens and young adults need more play, while seniors often prefer warm, quiet spots.
