The Norwegian Forest cat, aka 'The Viking Cat', is a large, semi-longhaired Norwegian breed. It is an ancient breed, and is one of the largest of all domestic breeds, with only the American Maine Coon being larger. It is a powerfully built cat with long hair, a full ruff, tuffeted ears and a bushy tail. The Norwegians front legs are slightly shorter than the hind legs. Its long outer coat is glossy and water resistant, while the thick undercoat adds protection against the cold.
