The Nebelung was developed in America, where a black housecat, Elsa, whose
father resembled a Black Angora cat, gave birth twice to blue semi-shorthaired
kittens in two different litters. The first kitten was a male, which was named
Siegfried and was born in 1984. Some months later there appeared a female kitten
of the same type and colour in the second litter. This female, of a slightly
lighter blue colour than her older brother, was given the name Brunhilde. The
owner of the kittens was Cora Cobb. Mrs Cobb realised that these two kittens
could become the base of a new breed. To make this plan come true, she contacted
a genetic expert by the name of dr. Solveig Pfleuger. After she had looked at
the cats she came to the conclusion that they where semi-longhaired Russian
Blues. Together with Mrs. Cobb she then wrote a breed standard and Mrs. Cobb, a
Wagner lover, gave them the name Nebelung.
The Nebelung should resemble the Russian Blue on al front except hair length. The coat of the Nebelung should be semi-longhaired and silky to the touch and of a beautiful silvery blue. Siegfried and Brunhilde became the basis for the Nebelung breed in America. The genetic base for this breed was very small with only two cats. To small to produce a healthy breed. Therefore Russian Blues where used to broaden the base of the Nebelung breed. Shorthaired kittens from these crossings are called Rus. Var, and can only be used to further breed Nebelungs. Because they may look like any ordinary Russian Blue, but they carry a longhair factor in their genes. And a long coat is undesirable in the Russian Blues. Therefore both breeds are separated by means of an extra code on the pedigrees of the shorthaired Nebelungs; Rus. Var. At one moment, Mrs. Cora Cobb heard of the existence of a Russian Nebelung, born out of two pedigree shorthaired Russian Blues. Finally Mrs. Cobb was able to track down the cattery in Russia and bought another Nebelung to breed with. At the moment the Nebelung breed has spread around the world even though there are not many breeders. Except for looks, the Nebelung also resembles the Russian Blue in character. They are very lovely, cuddling and intelligent cats that are very much attached to their humans. The name of the breed does credit to it misty blue coat.
The Nebelung started with Siegfried (1984) and Brunhilde (1985). The mother Elsa was a black domestic shorthair and the father resembled a Russian Blue. Elsa's father was a longhaired resembling a black angora. In May 1986, Siegfried and Brunhildes first litter was born and Cora Cobb decided to start a new breed. Cora contacted Dr. Solveig Pflueger, the TICA genetics specialist. Her advice was to describe this new breed as a longhaired Russian Blue. The Nebelung breed standard was written, which was based on the breed standard from a Russian Blue with one difference coat length. However for breeding a healthy Nebelung breed, "fresh" blood was needed preferably from a Russian Blue with longhair recessive. She found people interested in breeding and also people who were willing to mix in Russian Blue cats.
Separate from the American line, Nebelungs are born in Russian Blue litter. Some people say that Nebelung other than from Russian Blue lines are not Nebelung but simply mistakes in Russian Blue lines and not suitable for breeding. However for the Nebelung breeder an opportunity for creating new blood. Some Russian Blue breeders are against the Nebelung, for more information about this topic see opponents.
Nowadays there are Nebelung breeders in the USA, Germany, the Netherlands and Russia. Breeding will start up in Poland, France and the United Kingdom.
