Ojos Azules

Ojos Azules was a breed of shorthaired domestic cat originating in the USA, with unusual blue or odd eyes caused by a dominant blue eye (DBE) genetic mutation. The breed came in all coat colors; however, only particolors, colorpoints, and intermediate colors with a characteristic white tail tip were permitted. The breed also had a semi-longhaired coat variety, the Ojos Azules Longhair. Due to the lethal side effects of the Ojos Azules gene, breeders stopped working with this blue eye mutation and the breed became officially extinct.
