The Nebelung Cat is a long-haired breed, bred to resemble the Russian Blue with a long coat. The Nebelung breed was created in the 1980s by Cora Cobb, with the two founding cats being Elsa, a black short haired cat, and an unnamed blue domestic shorthair. The first mating of these two cats produced five black or blue shorthaired kittens as well as Siegfried born 1984 who was blue with medium long hair. The second mating produced five black or blue shorthaired kittens, as well as a black longhair female and Brunhilde born 1985, a blue longhaired female.
Cobb mated Siegfried and Brunhilde, and their first litter was born in 1986. The offspring of Siegfried and Brunhilde were eventually out-crossed to natural Russian Blues in order to replicate the Russian Blue type. Although the Nebelung is sometimes called a long haired Russian Blue, it is actually a different breed, as the Russian Blue does not produce longhaired offspring. The Nebelung will produce both longhair and shorthair offspring in the same litter.
The breed was officially recognised by The International Cat Association TICA in 1987 under the ‘new breeds’ category, and achieved full recognition as a Championship breed in 1997. They are not recognised as a breed in the Cat Fanciers Association CFA, in North America. The Nebelung is recognised by many smaller cat registries/associations throughout Europe and also the World Cat Federation WCF, as they mimic the natural, long established Russian Blue except for coat length.
Nebelung in German means ‘creature of the mist’. These cats are judged in TICA on the same standard as a Russian Blue with the exception of their coat, which is mid-length with a dense plumy tail. They have green eyes, and their fur must be ‘blue’ tipped with silver. When Nebelung kittens are born, they have blue eyes, but their eyes change to a yellowish colour before they reach the full intensity green
