What breed of European domestic cat is in the picture?

The Norwegian Forest Cat is a sturdy cat with a distinguishing double coat and easily recognizable body shape. This is a slow maturing breed, attaining full growth at approximately five years of age. The Norwegian Forest Cat, called the 'skogkatt' (forest cat) in Norway, is a natural breed and despite a feral appearance is not a descendant or a hybrid of any wild cat species. Forest Cats probably arrived in Norway from Europe, descendants of domestic cats introduced to northern Europe by the Romans.

The Norwegian Forest cat is strongly built and larger than an average cat. Adult females of this breed will typically weigh 3.6 – 8 kg (8 - 18 lbs), while males tend to weigh 4.5 to 9 kg (10 - 20 lbs). The breed has a long, sturdy body, long legs and a bushy tail. The coat consists of a long, glossy, thick and water-repellent top layer and a woolly undercoat and is thickest at the legs, chest, and head.

Their water-resistant coat with a dense undercoat developed to help the cat survive in the harsh Scandinavian climate.
