A Rare Genetic Trait
Odd-eyed cats, known scientifically as having heterochromia iridis, possess two different-colored eyes due to a genetic condition. This striking appearance is most common in white or mostly white cats, often linked to the kit gene responsible for coat pigmentation.
The Science Behind the Look
Heterochromia occurs when melanin levels differ between the eyes. One eye has lower melanin, resulting in a blue hue, while the other is typically yellow, green, or copper. This condition develops in kittens as they grow, with final eye colors stabilizing around 6–12 weeks of age.
Cultural Significance
In Turkey, odd-eyed Turkish Angora cats are cherished and protected as a national treasure. Some are even raised in Ankara Zoo to preserve their unique genetic heritage. These cats were historically a favorite among royalty and are still revered today.
Not Just White Cats
While often associated with white cats, odd eyes can also appear in other cats with specific genetic variations. The condition doesn’t affect vision, and these cats lead healthy lives with their captivating gaze.
