Norwegian Forest Cats have a thick fluffy double-layered coat, long tufts of fur in ears and between toes, and a long bushy tail to protect them against the cold. Their coat is essentially waterproof due to its coarse outer layer and dense underlay. They are very large cats with adult males weighing 6 to 10 kg (13 to 22 lb), while females are approximately half that size. Their hind legs are longer than their front legs. They are very intelligent, playful cats that enjoy human company but can get upset if left alone for a long period of time.
