Often described as a longhaired Russian Blue, this breed combines a luxurious plush coat with a loving, intelligent disposition, making it an ideal companion for quiet households.

Striking shimmering blue-gray semi-longhair coat, large vivid green or yellow-green eyes, a modified wedge-shaped head, and a balanced, muscular semi-foreign body type.

Physical Description

The Nebelung has a long, sturdy, and muscular body with a semi-foreign build, combining elegance with substance. They possess a modified wedge-shaped head with a flattened skull and a gentle concave curve from the brow to the nose. The legs are long and well-boned, ending in oval paws.

Coat & Coloration

The coat is medium-long with a soft, silky texture and a dense undercoat. The color is a distinct shimmering blue-gray, often featuring a silvery sheen due to tipped guard hairs. This specimen exhibits a striking white locket on the chest, which is a common trait in domestic mixes.

Coat Care

Requires weekly brushing to prevent tangles and remove loose hairs, with increased frequency during seasonal shedding in the spring and autumn. Bathing is rarely necessary unless the coat becomes soiled.

Eye Characteristics

Large, wide-set eyes ranging from vivid green to yellowish-green in adults. They have a slightly oval shape that gives the cat an alert, expressive, and slightly sweet facial expression.

Ear Characteristics

Large, pointed ears that are wide at the base and set far apart on the head, complementing the modified wedge shape of the skull. The ears often feature light furnishings inside.

Gentle, affectionate, quiet, and intelligent. Nebelungs are known for forming strong bonds with their chosen humans, often acting reserved around strangers while being deeply playful and loving with family members.

Diet & Nutrition

Requires a high-protein, premium-quality diet formulated for medium-to-large cats. Portion control is essential to prevent obesity, and fresh water should always be available via a fountain to encourage hydration.

Life Stages

Kittens are extremely playful and curious, maturing slowly over the course of two years to reach their full physical and coat potential. Adults maintain a balanced activity level, transitioning smoothly into a dignified senior phase.
