There is a surge in enquiries at cosmetic clinics for an ‘Instagram face’ which involves procedures such as high cheekbones, cat-like eyes and full lips. In this post I focus on cat-like eyes. Exactly what are ‘cat-like eyes’ on humans? I believe the phrase means to have eyes which are almond shaped, open and …
I think this is an excellent, even dramatic, example of sectoral heterochromia iridum in a domestic cat. It is normally referred to as ‘sectoral heterochromia’. Heterochromia is when the eyes are different colours. We sometimes call this “odd-eye” colour. The phrase ‘sectoral heterochromia’ means that the difference in colours occur across one eye, as …
This is an excellent example – I would say an extreme example – of iris melanosis in the eyes of an elderly cat. The picture caught my eye (excuse the pun). It comes from the Reddit.com website on which a member of that site (u/lilbeewin) posted a picture of her cat with the title: …

This is a photograph of an all-white Maine Coon cat with heterochromia iridum. In layperson’s language, this beautiful cat has odd-eye colour. And it is a classic case of odd-eye colour because one eye is yellow-gold and the other is blue. The reason why one eye is yellow-gold and the other blue is because …
The total amount of melanin (pigment) in the iris of the eye determines the range of eye colours in cats and in humans. The same principles apply to all animals with a similar eye anatomy.
