The DBE Gene
Dominant Blue Eye
Selkirk Rex & Devon Rex
The DBE (Dominant Blue Eye) gene is an extremely rare genetic trait in the Devon Rex, and even more so within the Selkirk Rex breed. It allows for the appearance of blue or intense blue eyes without being linked to the colourpoint gene (Siamese pattern) or the dominant white gene. A cat carrying the DBE gene can therefore display a full, tabby, or smoke coat while retaining natural blue eyes.
The DBE is an autosomal dominant gene, meaning that a single carrier parent can transmit this trait to a portion of its offspring. However, this gene remains poorly documented scientifically, and there is currently no reliable commercial DNA test to identify it with certainty. Its recognition therefore relies on phenotype observation, transmission history, and the rigorous exclusion of other known genes responsible for blue eyes.
Rakia
Selkirk Rex · DBE
Carrier of the Dominant Blue Eye gene, Rakia embodies the rare union of a rich brown coat and striking blue eyes — an exceptional genetic trait within the Selkirk Rex breed. We are the only cattery in Canada to breed Selkirk Rex DBE. (as of 2025)
Adamo
Devon Rex · DBE
A slow-maturing male from Latvia with a confident character and gentle presence, Adamo stands out for his dominant blue eyes — a rare and luminous expression that enhances both his gaze and his natural elegance within the Devon Rex breed.
A Responsibility, Not a Trend
It is essential to emphasize that very few breeders today possess the in-depth genetic knowledge required to work responsibly with the DBE gene. Responsible breeding of a DBE cat is far more complex than simply avoiding a DBE × DBE pairing. Numerous variables must be understood and evaluated before deciding to breed a DBE carrier with another cat of the same breed, including lineage stability, observed transmission across multiple generations, rigorous exclusion of other risk-associated genes, and comprehensive health and phenotypic monitoring of the offspring.
It is equally critical to note that the DBE gene, if worked without thorough knowledge and careful supervision by the breeder, can be associated with serious anomalies and has no place in ethical breeding. As a precautionary principle, this gene must be handled with extreme rigor and complete transparency.
An Exceptional Trait
In the Selkirk Rex and Devon Rex, the presence of the DBE gene remains exceptional, making it a genetic characteristic of great interest, yet one that must never take precedence over the health, temperament, and genetic stability of the breed. Any integration of the DBE into a serious breeding program must be part of a progressive, documented, and ethically driven approach — rather than a pursuit of rarity.
Our approach prioritizes knowledge, caution, and responsibility. The DBE gene is treated as a fascinating genetic trait, still evolving from a scientific standpoint, that demands humility, expertise, and a genuine commitment to the well-being of our cats and the future of the Selkirk Rex and Devon Rex.
