Domestic Long Hair isn't a breed. It's the label for a mixed-ancestry cat with a long coat, the fluffy counterpart of the Domestic Short Hair. These cats come from the general cat population, so they appear in every color and pattern, from tabby and calico to solid black and smoke. Some resemble a Maine Coon or a Persian without sharing that ancestry. Adults usually weigh 8 to 15 pounds, though long fur can make a cat look bigger than it is.
With no breed standard, size, coat texture and personality vary from cat to cat. What they share is a coat that needs regular brushing to prevent mats and hairballs, and the genetic diversity that tends to keep mixed cats healthy. In Great Falls, that thick coat is a real plus through the cold months, as long as the brushing keeps pace when the fur grows dense.
