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'. One indicator of the Ojos gene is a flattened tail-tip.
