PHOTOS: Adorable twin cats showcase their fascinating eye colors

These adorable cats — which are twins — showcase their contrasting blue and green eyes. The fascinating pair, Iriss and Abyss, live with their owner. Pavel Dyagilev, 34, in St. Petersburg, Russia. Pavel says that most people ask whether the cats eyes are real due to their unusual appearance.

The cats have a condition called heterochromia iridis, which causes each eye to vary in color. Dyagilev said: "When I found an ad on social media that two kittens were seeking a new home, I never imagined that I'd end up with two. But I looked through the pictures of kittens and saw two twins always together on the photos. And my heart melted.” (Caters News)
