Domestic Long Hair is a coat description, not a pedigree. These are mixed-ancestry cats with medium to long fur, and they come in every color and pattern, from tabby and calico to smoke and solid black. Most adults weigh 8 to 15 pounds, though the fluff can make a cat look bigger than it is. Some resemble a Maine Coon or Persian without sharing that ancestry.
Because there's no breed standard, temperament varies as much as looks. Many are affectionate and adaptable, while others are shy at first or bold from day one. The common thread is grooming: brushing a few times a week keeps mats and hairballs down, and more often during heavy sheds. In Hampton's humid summers, combing out loose undercoat helps the coat shed heat. With good care, these cats often live 12 to 18 years.
