Meet Pam Pam, a kitty with the most mesmerizing eyes

The reason Pam Pam’s eyes look like this is because of a condition called heterochromia iridis. It’s characterized by abnormalities in the iris, and those affected by the condition have one eye with a different color than the other. 

Another type of the condition, called segmental heterochromia, causes different colours in the same eye. Heterochromia can be caused by inbreeding, genetic inheritance, or mutation, and in some breeds of cats, like the Turkish Angora, heterochromia is a desirable trait that breeders try to maintain. 

Inherited heterochromia iridis is harmless, and it can be found in both animals and humans.
