Smoke Genetics
The Smoke color in Ragdolls is determined by the presence of the dominant inhibitor gene, denoted as 'I'. This gene suppresses the development of pigment in the undercoat, leaving it white or silver, while allowing the outer tips of the fur to retain their full color. A Ragdoll will express the Smoke phenotype if it has at least one copy of the dominant inhibitor allele (I/i or I/I). A cat with the genotype i/i will not be smoke and will have a uniformly colored coat. The 'I' allele is dominant,…
Color and Appearance
Smoke Ragdolls present with a solid color on the tips of their fur, but their most distinguishing feature is the white or silver-white undercoat. This creates a dramatic contrast, especially when the cat is in motion or when the fur is parted. Colorpoint Mitted Bicolor Van Kittens are born with a less pronounced smoke effect; the undercoat lightens and the contrast becomes more apparent as they mature, typically reaching its full expression by 1-2 years of age. The intensity of the smoke can als…
Paw Pads and Nose Leather
For Smoke Ragdolls, the paw pads and nose leather will correspond to their underlying solid color. For example, a Seal Smoke Ragdoll will have dark brown to black paw pads and nose leather, similar to a traditional Seal Ragdoll. A Blue Smoke will have slate gray paw pads and nose leather. Unlike Silver or Chinchilla colors, where the inhibitor gene can significantly lighten the overall appearance including the skin pigment, Smoke primarily affects the hair shaft's pigmentation. The underlying sk…

Smoke vs Other Colors
Smoke Ragdolls are often confused with Silver Ragdolls due to the presence of a light undercoat, but there are distinct differences. Smoke cats have a solid, pigmented topcoat with a white undercoat, creating a veiled effect. Silver cats, on the other hand, have a much more extensive reduction of pigment in the hair shaft, resulting in a lighter, often sparkling appearance throughout the coat, not just the undercoat. Smoke Silver Another common comparison is with traditional solid colors like Se…
Smoke Ragdoll
Introduction
The Smoke Ragdoll is a striking color variant characterized by a solid topcoat color with a distinct white or silver-white undercoat. This creates a shimmering, veiled effect as the cat moves, making the undercoat visible. Genetically, Smoke is produced by the presence of at least one dominant inhibitor gene (I/i or I/I), which suppresses pigment in the undercoat while allowing the topcoat to express its full color. This genetic mechanism results in a cat that appears solid-colored at first glan…
Quick Facts
History of the Smoke Ragdoll
The Smoke color, while not one of the original colors in the Ragdoll breed's foundation, emerged as breeders worked to expand the genetic diversity and aesthetic range of the breed. The inhibitor gene responsible for the smoke effect is present in many cat breeds, and its introduction into the Ragdoll lines was a natural progression as breeders sought to introduce new, visually distinct variations. The integration of the inhibitor gene was carefully managed to ensure it aligned with the Ragdoll'…
