Domestic Long Hair is the label shelters and veterinarians use for a mixed-ancestry cat with a long coat. These cats don't come from a pedigreed breed, so they appear in every color and pattern, from tabby and calico to solid black or smoke, and some resemble a Maine Coon or Persian without sharing that ancestry. Adults usually weigh 8 to 15 pounds, though long fur can make a cat look bigger than it is.
Size, coat texture and temperament vary, so meeting a cat tells you more than the label does. What most share is a coat that needs regular brushing to prevent mats and hairballs. In Skokie, where cats spend long winters indoors, shed fur collects fast, so a brush and a good vacuum are part of the deal. Mixed ancestry also tends to keep these cats healthy, with lifespans of 12 to 18 years.
