Distinctive Features
  • Pedigreed domestic cat breed (Felis catus), not a wild species; selected for a longhaired Russian Blue-like type.
  • Medium-long, fine, silky blue coat with noticeable silver sheen; minimal patterning.
  • Elegant semi-foreign build: slender body, long legs, fine-boned but athletic.
  • Wedge-shaped head, large ears, straight profile; overall refined, "Russian Blue" look.
  • Bright green eyes are strongly preferred and are a key identifier.
  • Full tail plume and a soft neck ruff (often more pronounced in adults and in winter).
  • Temperament often described as gentle, people-oriented, and sometimes reserved with strangers (individual variation).
  • Care: regular combing/brushing (often 2-3 times weekly; more during shedding) to reduce mats and hairballs.
  • Health: generally robust for a domestic breed; as with many cats, monitor dental health, weight, and routine cardiac/renal wellness at vet checks.
  • Distinguishing point vs Russian Blue: Nebelung is the longhaired counterpart; similar color/type, different coat length and grooming needs.

Sexual Dimorphism

Males are typically larger and heavier-boned, often developing a fuller ruff and tail plume. Females tend to be smaller, finer-featured, and slightly less heavily coated.

  • Larger overall size; broader chest and shoulders
  • More pronounced neck ruff and tail plume, especially in winter coat
  • May develop slightly fuller cheeks/jowls with maturity
  • Smaller, lighter build with a more delicate outline
  • Ruff and plume usually present but less dramatic
  • Often a slightly narrower head and finer facial features

Did You Know?

The name "Nebelung" comes from a German word meaning "mist" or "fog," referencing the breed's smoky blue coat.

Nebelungs are essentially Russian Blue-type cats with a medium-long, silky coat instead of a short one.

Their coat often has "silver tipping," making the blue look like it's dusted with frost when they move.

The breed began in the 1980s in the United States from a Russian Blue-like longhaired cat line.

Many are known for bonding strongly with one person and preferring a calm, predictable home.

They typically mature into their full coat and plume-like tail over several years, not all at once.

Like all domestic cats, they retain the classic feline toolkit: retractable claws, night-adapted vision, and a highly flexible spine.

Unique Adaptations

  • Medium-long, silky double coat with silver tipping: provides a plush, misty appearance distinct from the short coat of the Russian Blue.
  • Elegant, slender build: a refined body type (Russian Blue-like) that emphasizes agile, quiet movement.
  • Plumed tail and breeches (longer fur on hindquarters): hallmark longhair features that differentiate the breed from the base domestic shorthair population.
  • Bright green eyes (common breed goal): a striking identifier paired with the blue coat, though eye color can vary with age and lineage.
  • Domestic-cat adaptability: like other domestic cats, thrives in human environments and can be fully indoor with enrichment (climbing, hunting-style play).

Interesting Behaviors

  • Shadow-following: often trails a favorite person from room to room while staying politely out of the way.
  • Soft-voiced communication: tends to use gentle chirps or small meows rather than constant vocalizing.
  • Routine-sensitive habits: can prefer set feeding times, familiar furniture placement, and predictable visitors.
  • High-perch surveying: seeks vertical spaces to watch household activity with minimal commotion.
  • "Polite play" bursts: short, graceful sprints and pounces, then a return to calm lounging.
  • Selective socializing: may be reserved with strangers but affectionate and steady once trust is earned.

Cultural Significance

The Nebelung (Felis catus) is a purebred breed bred to look like a long-haired Russian Blue: a quiet companion with a slim shape and misty-blue shine. Its German name and Russian Blue link give it an elegant "fog cat" image, liked for calm nature and soft fur over bold patterns.

Myths & Legends

The Nebelung breed's origin story comes from early 1980s U.S. cats with long blue coats. Their look led to the name Nebelung ('creatures of the mist') and a Russian Blue-like cloak image.

The name is often linked in breed lore to a medieval German epic poem, lending the cats a romantic, saga-like aura even though the breed itself is modern.

Old European stories about blue or gray cats, not about one breed, called them quiet household guardians that brought calm and kept peace, a theme owners often use to describe the Nebelung (Felis catus) nature.

Many cultures believe a home cat's watchfulness and favorite resting spots can 'read' a house's energy. This idea is often tied to quiet, shy breeds like the Nebelung who choose calm perches.

Nebelung Traits: What to Know Before You Buy

Although they are recognized by TICA as their own breed, Nebelung cats are essentially longer-haired Russian blues. They have the Russian blue cat’s coat color of blue-gray with silver tips, but with medium-long strands of a double coat.

Being a Nebelung cat owner means having grooming and care responsibilities unique to the species. Both males and females need weekly brushing to ensure they do not develop matting. Although they are not especially needy, Nebelungs do not like lifestyle changes or routine disruptions, such as when home-based owners go back to office-based work or school. They can become anxious if not well-socialized as a kitten.

The breed is healthy overall without any major inherited health problems. But they can become finicky about their food and even spoiled eaters. This can lead to obesity and weight-related health problems. Otherwise, when well cared for, they often live as long as 18 years.

Origin

The Nebelung is a rather new breed, originating in America during the 1980s. A cat owner named Cora Cobb of Colorado admired the beautiful medium-long gray coat of one of her male Russian blue-type and female shorthair black cats’ offspring. She kept this kitten from their first litter and named him Seigfried after a character in a Wagner opera. Cora noted Seigfried’s uniquely sweet, gentle, and loyal nature and beautiful body characteristics she had not seen in her other cats. To pass these loving and attractive traits of Seigfried’s on, Cobb later bred the adult male with a similar medium-long coat female from a second litter with the same parents. That female was named Brunhilde, also after a character in the Wagner opera. The result of these two unique parents is the bloodline recognized as Nebelung today.

The cat breed’s name Nebelung, is German and means “creatures of the mist.” They have long, muscular, and athletic bodies with slightly pointed heads. Their foreheads are straight, and their nose tips are shallow with a concave curve. The cats’ ears are large and pointed with green to yellow-green eyes set widely apart. It is the breed’s coat that first makes them stand out. Their beautifully rich, blue-gray, and shiny medium-long double coats are fully developed by their second year of life. Adult males typically have more neck ruff than females, like their distant feline cousins, the lions.

Personality

Nebelungs make for great family companions.

Nebelungs are adored for their affectionate, loving, loyal, and sweet personalities. They are gentle yet playful, making them a perfect companion for family members of all ages. These intelligent cats closely bond with their owners.

Their devotion to their humans often leads these cats to follow family members around the house. They simply enjoy knowing what their people are doing and like to be part of the action, even just by observing. They are lap cats who enjoy being pampered and petted. In a family setting, the Nebelung often chooses one or two favorite humans with whom they bond most closely.

The breed feels most confident and secure within a well-established routine. They do not like change and require some time to adjust to moving from one household to another, the addition of new family members, or other disruptions. During such changes, it is important to show your Nebelung lots of love and affection to reassure them that all is well.

The Nebelung personality relates well with cat buddies, so that they can live and play within the same household. If your Russian blue longhair breed struggles with recent changes, it is often a good idea to find a compatible cat brother or sister they can befriend and enjoy.

You will rarely hear your Nebelung meowing. They are a soft-spoken breed that usually only vocalizes when something is not right in their world, such as when the litter box needs cleaning or their food dish is empty.

When visitors come to the home, the longhaired Russian blues typically hide under a bed or keep themselves at a safe distance. Otherwise, they are highly affectionate and love to engage in play with their loved ones.

Size and Weight

A Nebelung typically weighs about 7 to 15 lbs.

Nebelung cats are medium-sized in physical build, typically only weighing from seven to 15 pounds at a height of nine to 13 inches. They are longer than shorthair Russian blue cats, one of their original breeds. Their legs, tail, neck, and body all have longer or wider measurements than the famed Russian blues. Males and females do not vary widely in size or weight. But, as with most cats, males can be slightly larger, particularly after neutering. Males also often have a lion-like neck ruff that differentiates them from females and gives them a slightly bolder appearance.

Price

It is important to adopt a Nebelung from a reputable shelter, rescue, or breeder.

Because of their long blue-gray coats, bright green eyes, and sweet, gentle dispositions, Nebelung cats are in high demand. This demand affects their price. But also because they are a relatively new domestic cat breed recognized by multiple breeding associations, they are hard to find. This means they are not typically found in animal shelters or rescue centers for pet adoption, and prospective owners must find a reputable breeder.

If you are lucky enough to find one of this breed’s beautiful cats in a shelter, you will typically pay a price of anywhere from $50 to $200 for adoption. But if you purchase one from a reputable breeder, you can expect upfront costs of between $600 and $1200. It is important to be wary of people selling so-called Nebelung cats on the internet unless they have papers indicating the cat’s legitimacy as a member of this breed. Many medium-long-haired pets are listed on various sites under the breed, but long hair alone does not make the cat a Nebelung. There are many other traits specific to the breed and dictating their price, from their loving and gentle personality to their intelligence and key physical characteristics.

One of the most important breed facts is that owning a Nebelung is often more expensive than owning other breeds of cats, particularly shorthair breeds. Not only do they have the typical food, grooming, and vet care costs associated with any cat’s ownership, but they also require some special care and attention. Their long coats require weekly brushing to prevent tangles that lead to matting. They sometimes need to visit a groomer for thinning of the coat, matting removal, or a complete shave to grow a fresh coat.

Members of this breed are often picky eaters. Your new cat may come with expensive taste, turning its nose up to typical cat food and wanting a more costly brand. The average owner pays between $120 and $150 per month for their food, treats, and health supplements recommended by a veterinarian. These cats are also sensitive about the care and upkeep of their litter boxes, so you must be prepared to shoulder the cost of their preferred brand.

Routine veterinary care and other health costs for a Nebelung cat typically average around $138 per year, though costs can be higher depending on services and location.

Kittens

Kittens of the breed are among the cutest you can find in the cat world. They are fluffy, sweet, and playful. Their widely set green eyes make them appear as intelligent and curious as they are, eager to take in the world around them.

Kittenhood is an important time in any Nebelung’s life, as the fluff balls need early socialization and handling to ensure they are not anxious or timid cats. Of course, the species is known for running to hide in different rooms or under beds when visitors come into their domains. But being around other domestic cats, people, and pets is a great idea to help curb their natural shyness. Social exposure can also cause these kitties to give extra lap cuddles to the humans they love.

One of the cutest traits of Nebelung kittens is their quiet little meow. The breed is known for being quieter than many other types of cats. Throughout their lifetimes, these cats tend to “speak” only when they need to make a point, such as when their water bowl or food dish is empty. But as kittens, their sweet voices tend to be very soft and quiet. Some will vocalize in soft little squeaks as they learn how to communicate.

Like the adults, the breed’s kittens are medium-sized when compared to other cat breeds. But there is no denying the special cuteness of their irresistibly fluffy blue-gray coat.

Lifespan

Nebelungs are capable of living long, healthy lives with the proper care.

This breed of cats typically lives long, healthy lives and is generally considered healthy, though some individuals may be prone to conditions such as allergies, asthma, bladder stones, hypertrophic cardiomyopathy, and kidney disease. This means that their lifespan is largely determined by how their owners care for them and other factors. While most live between 13 to 16 years, it is not uncommon for members of this breed to live 18 years. Some have even lived to be as old as 20 or older.

Nebelung Breed vs. Mixed

Balinese Cat mixes can oftentimes be mistaken for Nebelungs

Although their most identifiable feature is their medium-long blue-gray hair, a Nebelung has many other important traits specific to their species. If they are not from this breed, they may be a mixed breed or a member of another medium-long family like the Oriental Longhair. The Oriental longhair is often mistaken for a Nebelung and vice versa because both breeds can have similar gray coats.

One of the most important facts to note about their physical appearance and confirm a cat is a Nebelung is the presence of widely set green eyes. TICA.org sets breed standards for the Nebelung and notes that some members of the cat breed have yellow-green eyes during their kitten phase. These deepen in color by the age of two years. At that time, you can note a green halo that forms around the pupil and an overall green color.

The breed’s coat is entirely blue-gray and medium-long. If a kitten or cat has patches of other colors or a non-gray coat, it is possibly a mixed cat, an Oriental longhair, Balinese, Javanese, Himalayan, or other breeds. Other coat traits that can make the breed easier to identify are the silver tips on the blue-gray hairs that give the cat’s coat a shimmery, misty look.
