Domestic Long Hair isn't a breed. It's the label used for a mixed-ancestry cat with a long coat, the fluffy cousin of the Domestic Short Hair. These cats come from the general cat population, so they show up in every color and pattern, from tabby and calico to solid black and smoke. Some resemble a Maine Coon or Persian without sharing that ancestry.
Size, coat texture and personality vary from cat to cat, so meeting the cat in front of you tells you more than the label does. What they share is a coat that needs regular brushing to prevent mats and hairballs. In Royal Oak, where homes range from older bungalows to downtown condos, that coat and a calm indoor routine move easily from one kind of home to another.
