Both of the cats balance a ball on their heads, in Saint Petersburg, Russia, Sept. 2016.

Beauty is in the eye of the beholder when it comes to these beautiful twin cats with mismatched eyes. Named Iriss and Abyss, both sisters have a genetic condition called heterochrmomia, which produces a difference in coloration in the eyes due to a lack of melanin. Pavel Kasianov from Saint-Petersburg adopted the crossbred 10-month-old kittens after seeing an advert online. as Along with their hypnotizing eyes, the cats also have snow white fur. Since getting the cats, Pavel has set up an Instagram page for the twins which boasts more than 70,000 followers. [Photo/VCG]
