Today's Fun Fact Friday is brought to you by 🐱 Cal 🐱 the kitty with heterochromia!
Heterochromia means that the irises of each eye is a different colour. In most cases, one eye will be blue 🔵 and the other will be green 🟢, yellow 🟡 or brown 🟤!
Fun fact about heterochromia in cats:
While heterochromia is rare, it is more likely to occur in white cats or cats with any amount of white fur! 🤍🐱
The gene that causes cats to be white or to have white spots can prevent pigment from reaching one eye during the cats early development. This means that one eye remains the blue colour of a young kittens' eyes, while the other eye is a variable colour (green, yellow or brown)! 🤯🐱
