I’m not sure if this is Ugly or Dirty – my friend’s white kitty cats. Yes, he named them Ugly and Dirty. They were born from the same litter, all white fur coat, and one blue eye and one hazel green eye. Heterochromia is more commonly found in animals than humans, although it is possible. Statistically, the anomaly of two eye colors is a categorized as a “rare disease by the Office of Rare Disease, meaning it affects less than 200,000 people in the U.S. population. As I researched on this topic, I learned that heterochromia correlates to all-white cats and usually always one eye is blue.
In the case of Ugly and Dirty, they are both fit the archetype perfectly. What I thought unique about there case was that one cat has green and blue eyes, respectively, while the other cat has blue and green eyes, respectively. When I first met these adorable fur balls, I couldn’t get over their mysterious eye discoloration. However, heterochromia can be passed on genetically and is caused by the lack of melanin in one eye to cause a discoloration from the other eye.
Beauty is always in the eye of the beholder, and these kitties don’t need to be perfectly symmetrical to be loving and cuddly.
