Domestic Long Hair isn't a breed. It's the label for mixed-ancestry cats with medium-to-long fur, and it covers every color and pattern, from tabby and calico to smoke and solid black. Some look like a Maine Coon or a Persian without sharing that ancestry. Adults usually weigh 8 to 15 pounds, though the fluff makes many look bigger.
Because there's no breed standard, personality varies widely: some are lap cats, others are bold climbers, and some take a while to relax. What they share is a coat that needs regular brushing to prevent mats and hairballs. In Springfield, where winters are damp and many homes are apartments, a brush, a window perch and a routine of indoor play go a long way. Spend time with a cat before deciding.
