Domestic Long Hair is a coat description, not a breed. It covers mixed-ancestry cats with medium to long fur, so you'll see every color and pattern, from tabby and calico to solid black and smoke. Size, build and coat texture vary, and adults commonly weigh 8 to 15 pounds. Some look like a Maine Coon or Persian without sharing that ancestry.
What these cats have in common is a coat that needs brushing to prevent mats and hairballs, plus the broad genetic variety that tends to keep mixed cats healthy. In Yakima, where homes run from older houses to small multiplexes, a Domestic Long Hair usually adapts well. Spending time with a cat tells you far more about personality than the coat label does.
