This beautiful cat has sectoral heterochromia, where the iris contains two different colours due to a lack or excess of melanin. 😻😻😻 Complete heterochromia occurs when one iris a totally different colour from the other. It’s most prevalent in cats and dogs, but about 1% of the human population has it too. 📷: raoeang/Imgur #cat #instacute #science #sciencealert http://ift.tt/2gMfW5Y
