Domestic Medium Hair is a coat description rather than a breed. The label covers mixed-ancestry cats with fur between short and long: a fuller tail, tufts between the toes and a soft undercoat, but no heavy ruff. Adults usually weigh 6 to 14 pounds and can be any color or pattern, from tabby to tuxedo to calico.
Size, personality and health follow each cat's background more than its coat, so meeting a cat tells you more than a label does. In St. Petersburg, most live indoors, where air conditioning, screened windows and a good scratching post keep them comfortable through the long warm season. Expect a bit more brushing than a shorthair needs, especially when the coat sheds heavily in spring and fall.
