Traits
Origin & history
Denver, 1980s: a black domestic shorthair produced two blue, semi-longhaired kittens — Siegfried and Brunhilde, named from Wagner. Owner Cora Cobb saw a lost type in them: the longhaired Russian Blues that had appeared in Victorian records and vanished. She built the breed with Russian Blue outcrosses and gave it a German name — Nebelung, "creature of the mist" — for the smoke-silver coat. TICA recognised it in 1987; it remains a quiet rarity.
Appearance & size
A graceful three-to-five-kilogram cat in flowing blue-grey silk, each guard hair silver-tipped so the coat swirls like fog in motion. The plumed tail, neck ruff and britches build over years; the luminous green eyes complete slowly like the Russian Blue's. The overall impression is deliberate elegance — a cat drawn in smoke.
Personality & temperament
The Nebelung loves like its shorthaired ancestor: selectively, deeply, on its own schedule. Strangers see a vanishing act; the family gets a gentle shadow that follows favourite people, converses in tiny chirps and treasures routines like heirlooms. It is calm, sensitive and quietly playful — sudden chaos unsettles it, predictable warmth unlocks it. Patience during the trust-building weeks pays lifelong dividends.
Indoor or outdoor living
An indoor breed for calm homes: window seats, warm retreats, stable routines. A secured balcony pleases it; commotion and constant visitors do not. It shares well with gentle, quiet cats — whirlwind housemates stress it. Frame in Indoor cat or outdoor cat?
Enrichment & activity
Moderate and thoughtful: daily gentle play, puzzle feeders and fetch rounds with its trusted person. The clever head enjoys quiet challenges; loud games are declined with dignity.
Grooming
The silky semi-long coat carries modest undercoat and mats little: combing twice a week keeps the mist flowing, slightly more in moult.
Feeding & health
A robust rarity without notable hereditary diseases — the Russian Blue base serves it well; ask breeders for general heart checks. Portion via the food amount calculator: the calm temperament pads out readily. Like its ancestor, the breed often produces less Fel d 1 — an allergy candidate worth personal testing.
Costs
Kittens from good lines cost €900–1,300 — few breeders, real waiting lists. Running costs are modest; see the cat cost calculator.
For beginners, children and other pets
Best with calm households and older, gentle children; toddler noise clashes with the sensitive nature. Quiet cats make good companions. Considerate beginners in peaceful homes succeed — the breed needs patience, not expertise.

Frequently asked questions
Is the Nebelung just a longhaired Russian Blue?
Essentially — the breed rebuilt the lost Victorian longhair type on Russian Blue genetics. Character and colour came along.
What does Nebelung mean?
German for 'creature of the mist' — after the fog-like swirl of the silver-tipped coat, with a Wagner nod from the founder kittens' names.
Are Nebelungs shy?
Reserved with strangers, devoted to their circle — the Russian Blue two-tier heart in semi-long dress. Patience unlocks it.
How much grooming does the coat need?
Combing twice a week; the silky texture mats little for its length.
Are Nebelungs allergy-friendly?
Often — the ancestor's lower Fel d 1 tendency frequently carries over. Test personal contact before deciding.
How rare is the breed?
Genuinely rare: few catteries worldwide, waiting lists standard. Plan the search early.
