Nebelung: The Long-Haired Blue Cat

The Nebelung is a longhaired Russian Blue, a characterization that is accurate yet somewhat limited, since the Nebelung is officially recognized as a breed in its own right and not merely as a longhaired variety of the Russian Blue. Both breeds carry the same distinctive blue-silver coat, the same temperament of quiet loyalty and reserved intelligence, and genetically close relations.

The difference is the gene that determines coat length: the Nebelung carries a recessive long-hair gene that the standard Russian Blue does not express.

The Nebelung is a young breed by the standards of cat fancy, developed in the United States in the 1980s. Its name comes from the German word for mist or fog, a reference to its shimmering, ethereal coat.

History and Development

The Nebelung was created by Cora Cobb of Denver, Colorado, in the 1980s. Elsa, a black domestic shorthair belonging to Cobb's son, was bred to a blue male and produced a litter that included a longhaired blue male kitten that Cobb named Siegfried, after the hero of the German Nibelung saga. A subsequent litter from the same parents produced a longhaired blue female named Brunhilde, completing the Nibelung reference.

Cobb became committed to developing these cats into a formal breed. She took advice from TICA geneticist Dr. Solveig Pflueger and drafted a breed standard based on the Russian Blue but with semi-long hair.

The International Cat Association (TICA) granted the Nebelung championship status in 1997. The breed is also recognised by several other international registries, though not currently by the CFA. Population numbers remain modest, the Nebelung is a rare breed even by the standards of less common pedigree cats.

Genetics: Russian Blue Plus Long Hair

The Nebelung's genetics are straightforward. The Russian Blue's blue coat is the dilute expression of black. The Nebelung has the same blue coat genetics, plus a recessive long-hair gene.

Longhaired kittens born to Russian Blue parents in Russia in the early 1990s confirmed that the recessive long-hair gene is naturally present in the Russian Blue population. When two carriers are bred together, some offspring express the long-hair gene and have the Nebelung coat.

In current breeding practice, Nebelungs can be produced by breeding Nebelung to Nebelung (which consistently produces longhaired blue kittens) or by outcrossing with Russian Blues (which produces some shorthaired blue kittens alongside some longhaired blue kittens, with the shorthaired kittens carrying the longhair gene as unexpressed carriers).

This outcrossing with Russian Blues is permitted in TICA's Nebelung breed standard and serves the important function of maintaining genetic diversity in the small Nebelung population.

Physical Characteristics

The Nebelung is a medium-sized cat of the Russian Blue body type: semi-foreign, meaning neither the extreme elongation of Oriental breeds nor the compact roundness of Persian-type breeds.

Coat. The defining feature. The coat is medium-long, with a silky outer coat and a dense, soft undercoat. The collar (ruff) around the neck is fuller than on the body. The tail is heavily furred. The overall effect, combined with the blue-silver colour, is of an exceptionally beautiful, light-catching coat that changes appearance with the cat's movement.

Colour. Blue only, with silver tipping on the guard hairs. The silver tipping gives the coat its characteristic luminous quality. Kittens are sometimes born with faint ghost markings (tabby pattern) that disappear as the adult coat develops.

Eyes. Vivid green is the adult eye colour, reached gradually from yellow-green in kittens.

Temperament

The Nebelung shares the Russian Blue's characteristic temperament to a remarkable degree.

Key characteristics:

Quietly devoted. The Nebelung bonds deeply with its family and follows its chosen people with consistent, undemanding loyalty. It is not a lap cat in the demanding sense, it does not insist on physical contact, but it wants to be in the same room and to know where its people are.

Reserved with strangers. Nebelungs are typically cautious with unfamiliar people and may hide when visitors arrive. This is a consistent trait that prospective owners should understand and respect. A Nebelung that trusts you is affectionate and warm, one that does not know you yet will be invisible.

Gentle and quiet. The breed rarely vocalises except when necessary. Its voice, when used, is soft.

Sensitive to routine. Nebelungs are creatures of habit. They prefer consistent feeding times, consistent environments and consistent handling. Changes in routine, moves, new animals, new people, schedule disruptions, can cause stress in this breed.

Intelligent. The breed is capable of learning household patterns, routines and even simple games with minimal training.

Grooming

The Nebelung's semi-long coat requires regular brushing, approximately once a week, to prevent tangles, particularly around the collar and hindquarters. The coat is naturally silky and has less tendency to mat than more densely coated longhaired breeds, but it does require attention.

Spring brings the heaviest coat shedding and demands more frequent brushing than any other season.

Health

The Nebelung is a generally healthy breed. Given its close relationship to the Russian Blue, the health concerns that apply to that breed are relevant:

• No breed-specific heritable disease at high frequency is documented
• Urinary tract issues are occasionally reported but not significantly elevated compared to other breeds
• Obesity can be a concern given the breed's moderate activity level and love of routine feeding

Life expectancy is typically 15-18 years.
