BEAUTY is in the eye of the beholder when it comes to these beautiful twin cats, who have mismatched eyes. Named Iriss and Abyss, both sisters have a genetic condition called heterochrmomia, which produces a difference in colouration in both eyes due to a lack of melanin. Pavel Kasianov, 31 from Saint-Petersburg Russia, adopted the crossbred 10-month-old kittens after seeing an advert online. As well as their hypnotising eyes, the cats also have snow white fur adding to their unique look. Since having the cats, Pavel has set up an Instagram page for the twins which boasts more than 70,000 followers. To find our more, visit https://www.instagram.com/sis.twins/
