Domestic Long Hair isn't a breed. It's the label used for mixed-ancestry cats with a long coat, the fluffy counterpart of the Domestic Short Hair. These cats come from the general cat population, so they appear 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.
With no breed standard, size, coat texture and personality vary from cat to cat. Most adults weigh 8 to 15 pounds and live 12 to 18 years. The shared thread is a coat that needs regular brushing to prevent mats and hairballs, plus the genetic diversity that tends to keep mixed cats healthy. In Abilene, as anywhere, meeting the cat tells you far more than the label does.
