The Nebelung is a rare pedigree breed of domestic cat. Nebelungs have long bodies, wide-set green eyes, long and dense fur, and mild dispositions. The cat is related to the Russian Blue, but with longer, silkier hair, and is in fact sometimes called the Long-haired Russian Blue. Nebelung cats are characterized by a long, graceful neck and body, long legs, long or medium coat, and long tail. Slightly oval eyes are a vivid green color, or sometimes a yellow-green. Large, pointed ears sit atop a modified wedge-shaped head that is more pointed than rounded. The overall appearance is of a long, sturdy, well-muscled cat. (Source: Wikipedia.org, CC BY-SA)
