Domestic Long Hair isn't a breed. It's the label for a mixed-ancestry cat with a long coat, so you'll see every color and pattern, from tabby and calico to solid black and smoke. Some resemble a Maine Coon or Persian without sharing that ancestry, and most weigh 8 to 15 pounds, with fur that makes them look bigger than they are.
Because there's no breed standard, size, coat texture and personality vary from cat to cat, and meeting the cat tells you more than the label does. What they share is a coat that needs regular brushing to prevent mats and hairballs. In Lewisburg's cold winters, that thick fur feels at home in a warm house, and mixed ancestry tends to keep these cats healthy.
