Domestic Long Hair isn't a breed. It's the label used for a mixed-ancestry cat with a medium-to-long coat, the fluffy counterpart of the Domestic Short Hair. These cats come in every color and pattern, from tabby and calico to solid black, smoke and bicolor, and some look a lot like a Maine Coon or Persian without sharing that ancestry. Adults usually weigh 8 to 15 pounds, and the long fur can make them look even bigger.
Because there's no breed standard, size, coat texture and personality vary from cat to cat. What they share is a coat that needs regular brushing to prevent mats and hairballs. In Lubbock, where the air is dry and dust blows in on windy days, a short brushing routine also keeps grit and tangles from building up. Meeting the cat will tell you far more than the label does.
