Domestic Medium Hair is a coat description, not a breed. It covers mixed-ancestry cats whose fur falls between short and long, often with a fuller tail, tufts between the toes and a soft undercoat, but without a heavy ruff. These cats come from the general cat population, so they appear in every color and pattern. Most weigh 6 to 14 pounds and live 12 to 18 years.
Because the ancestry is mixed, size, personality and health vary from cat to cat. Expect more brushing than a shorthair needs, especially during spring and fall shedding, to keep hairballs and mats in check. Many are affectionate and curious once settled, but a shy cat may need time and a quiet room. Spending time with a cat in person is the best guide to temperament.
