This is Pam Pam and we guarantee you that she has the most beautiful eyes you will ever see. She has those unique looking eyes due to a condition called heterochromia iridis.
The condition causes abnormalities in the iris, so those who have that condition have one eye with a different color than the other.
While this condition can be caused by inbreeding, genetic inheritance, and mutation, in some breeds of cats, such as the Turkish Angora, it is a desirable trait so the breeders try to maintain it.
There’s also another type of heterochromia called ‘segmental heterochromia’ and it causes different colors in the same eye.
Inherited heterochromia is harmless, and both humans and animals can have this condition.
