Nebelung

Cat

The Nebelung is a rare breed of the domestic cat. Nebelungs have long bodies, wide-set green eyes, long and dense fur, and mild dispositions. The name Nebelung--apparently a portmanteau of the German word (Nebel) for Mist or Fog and a medieval Germanic saga, Nibelungenlied -- is perhaps derived from the cat's distinctive silky blue-grey coat and from the breed's progenitors, who were named after the two major figures in the Nibelungenlied, the German warrior Siegfried and the Icelandic queen Brunhilde.
