Domestic Medium Hair is a coat description, not a breed. It covers mixed-ancestry house cats whose fur falls between short and long, usually with a plumed tail, tufts between the toes and a soft undercoat. They come in every color and pattern, so a tabby, a tuxedo and a calico can all carry the label.
Because the ancestry is mixed, size, personality and health vary from cat to cat. Most are medium-sized and sturdy, and many live 12 to 18 years indoors. In Laredo the coat matters most in warm weather: expect extra shedding in spring and fall, and plan on brushing to keep mats and hairballs down. The best guide to temperament is spending time with the cat, not reading the label.
