Ojos Azules are a relatively new
breed of domestic
cat. Cats with dark blue eyes were discovered in
New Mexico among
feral cat populations. The first cat, discovered in 1984, was a
tortoiseshell named Cornflower. She was bred to males without the trait, which proved to be dominant, as all her kittens showed it. The breed was founded and named Ojos Azules,
Spanish meaning 'Blue Eyes'.Ojos Azules are remarkable for their deep blue eyes. Unlike the blue eyes seen linked to the genes in
bicolor cats and cats with
point coloration, both of which suppress pigmentation, this gene is not linked to any certain fur color or pattern, giving the opportunity to have cats with dark coats and blue eyes. The depth of color in the eyes is greater even than that seen in a
Siamese , and does not cause squinting,
deafness or cross-eye.Ojos Azules are a very rare breed. In 1992, only ten were known. The breed, in both short and long hair variety, was accepted for registration by TICA in 1991. The TICA Ojos Azules Breed Group Standard is dated 5 January 2004. Only cats expressing the deep blue eye gene have been called Ojos Azules. It was recently discovered that cranial defects may be linked to the gene, and breeding was temporarily suspended.
Following genetic investigation by
Solveig Pflueger, breeding resumed in a small way with attempts to breed Ojos Azules without the lethal genetic defects. It was discovered that when the gene is
homozygous it causes cranial deformities, white fur, a small...
