Introducing Pam Pam, the adorable feline whose striking eyes are sure to capture your attention. Her eyes are so mesmerizing that you might find it hard to look away, but don’t stare for too long! Pam Pam’s distinctive appearance is due to a condition called heterochromia iridis. This rare condition causes one eye to have a different color than the other, and in some cases, segments of the same eye may display varying colors. Heterochromia can occur due to genetic inheritance, mutation, or inbreeding. Interestingly, some cat breeds, such as the Turkish Angora, consider this trait desirable and even breed for it. This condition poses no harm and is also prevalent in humans and other animals. For more examples of animals with heterochromia, check out our comprehensive list.
