Meet The World’s Most Beautiful Twin Cats!

Meet Iriss and Abyss, the world’s most beautiful twin cats! The nine-month-old feline sisters from Saint Petersburg were adopted when they were three months old.

Both sisters have heterochromatic eyes, which means that they are of different color, as a result of the relative excess or lack of the pigment melanin.

There are three kinds of heterochromia of the eye. In complete heterochromia, one iris is a different color from the other. In sectoral heterochromia, part of one iris is a different color from its remainder and in “central heterochromia” there are spikes of different colors radiating from the pupil.
