Domestic Long Hair is a coat description, not a pedigree. Shelters use it for mixed-ancestry cats with medium to long fur, and they turn up in every color and pattern, from tabby and calico to smoke and bicolor. Some resemble a Maine Coon or Persian without sharing that ancestry, and most weigh between 8 and 15 pounds.
Because there's no breed standard, personality and size vary from cat to cat. What these cats share is a coat that tangles without regular brushing and sheds moderately to heavily. In Toms River, that means keeping a brush handy through humid summers and dry, heated winters, and checking for mats behind the ears and under the legs. Mixed ancestry usually brings broad genetic diversity, which tends to support good health.
