Domestic Long Hair isn't a recognized breed. It's the label used for mixed-ancestry cats with a long coat, the fluffy counterpart of the Domestic Short Hair. They come in every color and pattern, from tabby and calico to solid black, smoke and bicolor, and some resemble a Maine Coon or Persian without sharing that ancestry. Most adults weigh 8 to 15 pounds, though long fur can make a cat look bigger than it is.
Because there's no standard, size, coat texture and personality vary from cat to cat, so time spent with a cat tells you more than the label does. What the coat has in common is upkeep: regular brushing prevents mats and hairballs, and shedding runs moderate to heavy. In York, where most cats live indoors in rowhouses and apartments, that routine and a few play sessions a day matter more than square footage.
