Domestic Long Hair is a coat description, not a pedigreed breed. Shelters use the label for mixed-ancestry cats with medium to long fur, so these cats come in every color and pattern, from tabby and calico to solid black, smoke and bicolor. Some resemble a Maine Coon or Persian without sharing that ancestry. Most adults weigh 8 to 15 pounds, and many live 12 to 18 years.
Size, coat texture and personality vary a lot from one cat to the next, so meeting a cat tells you far more than the label does. What they share is fur that needs regular brushing to prevent mats and hairballs. In Bartlett, where summers are long and humid, steady brushing keeps a thick coat comfortable, and indoor living keeps burrs and outdoor hazards away from it.
