Domestic Long Hair isn't a breed. It's the label shelters and veterinarians use for a mixed-ancestry cat with a long coat, the fluffy counterpart of the Domestic Short Hair. Because these cats come from the general cat population, they show up in every color and pattern, from tabby and calico to solid black and smoke, and some resemble a Maine Coon or Persian without sharing that ancestry.
Size, coat texture and personality vary from cat to cat, and most adults weigh roughly 8 to 15 pounds. What they share is a coat that needs regular brushing to prevent mats and hairballs. In Huntington that routine is the same all year, and meeting a cat tells you far more than the label does.
