Domestic Long Hair isn't a breed. It's the label used for mixed-ancestry cats with a medium-to-long coat, the fluffy counterparts of the Domestic Short Hair. They come 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.
Because there's no breed standard, size and personality vary from cat to cat, though most adults weigh 8 to 15 pounds. What they share is a coat that needs regular brushing to prevent mats and hairballs. In Cape Coral, that means a cat that does best indoors, with a brushing routine and a cool spot to rest. Meeting the cat tells you far more than the label does.
