The Nebelung — from the German Nebel, meaning “mist” or “fog” — is a rare, relatively young American breed prized for its silvery, fog-colored coat and quietly devoted nature. The first kittens that would become the foundation of the breed were born in the United States in 1986, and The International Cat Association (TICA) granted formal recognition in 1987. The Nebelung is still uncommon today, but its admirers value it for the same reason its breeders did from the start: it carries the elegance of a Russian Blue in a softer, longer-haired form.

History
The Nebelung traces its origins to a single American breeder, Cora Cobb, whose Russian Blue-type cats occasionally produced semi-long-haired kittens. Two of these — Siegfried and Brunhilde, named after characters from the medieval epic Nibelungenlied — became the foundation of a deliberate breeding program. Russian Blues and selected long-haired domestic cats were used to set the type, and TICA accepted the Nebelung as a separate breed in 1987. The World Cat Federation (WCF) followed, while the Cat Fanciers’ Association (CFA) does not currently recognize the breed. Numbers remain small worldwide, so finding a well-bred kitten can take patience and often a spot on a waiting list.

Appearance
The Nebelung is a medium-sized cat with a foreign body type: long-bodied, fine-boned, and elegantly muscled rather than stocky. Males typically weigh 8 to 15 pounds and females 6 to 10 pounds. The defining feature is the coat — a semi-long, double layer in solid blue with silver tipping that gives the breed its characteristic misty shimmer. The hair is finer and softer than a Persian’s, with a noticeable ruff around the neck and longer breeches on the hind legs.
The eyes are a vivid green and slightly almond-shaped, set in a modified wedge-shaped head with large, broad-based ears. Kittens are often born with yellow eyes that gradually deepen to green as they mature, so a young cat’s eye color is not always a reliable guide to the adult it will become.
Personality
Nebelungs are intelligent, gentle, and reserved. They form strong bonds with their household but tend to single out one person as a favorite, lavishing that person with quiet affection and trailing them from room to room without ever becoming demanding. With strangers they are cautious and may disappear until visitors leave. They are observant rather than vocal — when they do speak, it is in a soft, almost whispered voice.
Despite an appearance of dignified calm, Nebelungs are playful and curious. They enjoy interactive toys, puzzle feeders, and a high vantage point from which to survey the household. They dislike loud noise, sudden change, and chaotic environments, which makes them better suited to calm homes than to households with very young, boisterous children.

Grooming and Care
Although the Nebelung’s coat looks demanding, grooming needs are only moderate. A thorough comb-through two or three times a week — first with a wide-toothed comb, then a fine-toothed one — is enough to prevent mats, with extra attention during the spring and fall shedding seasons. Bathing is rarely necessary; when it is, use a gentle, unscented shampoo and dry the coat thoroughly to avoid chills.
Check the ears weekly and clean them only when wax is visible, using a vet-approved ear cleaner. Brush the teeth several times a week to reduce the risk of dental disease, and trim the claws every two to three weeks. Provide a quiet feeding spot, fresh water at all times, and a sturdy scratching post. Nebelungs adapt well to apartment living as long as they have vertical space, window perches, and predictable routines.

Health
The Nebelung is generally a robust, long-lived breed, with a typical lifespan of 11 to 18 years and reports of individuals reaching 20 with attentive care. Because the gene pool is shared with the Russian Blue and other domestic cats, no breed-specific genetic disorders are widely documented. Even so, owners should watch for the conditions that affect cats in general — obesity, dental disease, urinary tract issues, and hypertrophic cardiomyopathy, the most common form of feline heart disease described by the Cornell Feline Health Center.
Schedule annual veterinary check-ups, keep core vaccinations and parasite control current, and feed a complete, age-appropriate diet in measured portions. Diet is the single biggest factor in keeping a Nebelung healthy: kittens benefit from four to five small meals a day, while adults do well on two. Routine wellness exams and preventive care are emphasized in the AVMA’s resources for pet owners.

Living With a Nebelung
The Nebelung gets along well with other cats and with calm, cat-savvy dogs, but it does not enjoy noisy households. Given a quiet home, attentive companionship, and a consistent routine, it returns its family’s investment with years of loyal, soft-spoken company. This is a cat that rewards the people who slow down to meet it on its own terms.

Frequently Asked Questions
What is the difference between a Nebelung and a Russian Blue?
The two breeds share ancestry and the same blue, silver-tipped coloring, but the Nebelung has a semi-long, double coat while the Russian Blue is short-haired. In temperament they are very similar — both are reserved, quiet, and deeply attached to their chosen person — so the most reliable way to tell them apart is coat length.
Are Nebelung cats hypoallergenic?
No. No cat breed is truly hypoallergenic, and the Nebelung is no exception. Allergic reactions are triggered by the Fel d 1 protein found in cat saliva and skin, not by hair length, so a longer coat neither helps nor hurts. People with mild sensitivities should spend time around the breed before committing.
Are Nebelungs good with children and other pets?
Yes, with the right environment. Nebelungs are gentle and tolerant of respectful older children, other cats, and calm dogs. What they dislike is noise and unpredictability, so very young or rowdy children can overwhelm them. A quiet, routine-driven household brings out their best.
How rare is the Nebelung cat?
The Nebelung is one of the less common pedigreed breeds. Because it descends from a small foundation population and relatively few breeders work with it, kittens can be hard to find and waiting lists are typical. Buyers should expect to research registered breeders through associations such as TICA and be prepared to wait.
Do Nebelungs need a lot of grooming?
Less than their fluffy appearance suggests. Combing two or three times a week prevents mats and keeps shedding under control, with a little extra effort during seasonal coat changes. They do not require professional grooming or frequent baths.
