The term describes a specific color variation within a well-known breed of domestic longhaired feline. The designation refers to the cat’s coat coloration: a diluted version of black, appearing as grey or slate blue, combined with a silver undercoat that creates a shimmering effect. This combination produces a visually striking and relatively uncommon appearance within the breed.
Individuals exhibiting this coloration are often sought after for their aesthetic qualities. This particular coat is not simply a matter of visual appeal; its presence provides insights into the genetics influencing feline pigmentation. Tracing the lineage of these animals offers valuable information for breeders aiming to understand and potentially reproduce this trait consistently. Furthermore, the unique genetic makeup associated with the coat type can contribute to studies investigating broader aspects of feline health and inherited characteristics.
