Domestic Long Hair isn't a breed. It's the label used for a mixed-ancestry cat with a long coat, so these cats come in every color and pattern, from tabby and calico to smoke and solid black. Some resemble a Maine Coon or Persian without sharing that ancestry, and adults usually weigh 8 to 15 pounds, though long fur can make them look bigger.
Personality, size and coat texture vary from one cat to the next, so spend time with the cat you're considering. In Garland, the shared needs are practical: regular brushing to prevent mats and hairballs, a cool resting spot through the hot months, and an indoor home that keeps the coat clean and the cat away from traffic and coyotes. Mixed ancestry tends to bring good genetic diversity, which helps keep many of these cats healthy.
