Legend said there were cats in the forests that could climb trees like no other, appearing and disappearing almost magically. Cats that could tell what lies in the heart of a man. The Legend of the Norwegian Forest Cat. The origin of these big cats is uncertain since they might be related to short-haired cats Vikings used as mousers on their ships or long-haired cats brought to Scandinavia by Crusaders. The Norwegian Forest Cat is the official cat of Norway. Strong, muscular, and very loving companions, with a great bond with their parents. The weight ranges between 13 to 22 pounds, and their long and thick waterproof coat makes them look even bigger. The coat has been providing a natural protection from rain, snow and very low temperatures, but it’s still silky and needs to be groomed every day. They are territorial hunters, patrolling several times a day. They love to chase toys and act tuff, to be groomed and being up high to observe surroundings closely.
