“Our black cats with especially green eyes usually go home pretty quickly,” shares Gabby Stroup, shelter manager at North Fork Animal Welfare League. Photography ©aluxum | iStock / Getty Images Plus. Of all the types of cats with green eyes, among the most cherished are rescue cats! As evidenced by the number of rescue kitties who are in the hallowed celebrity circle, there are many gorgeous kitties with green eyes ready to go home at your local shelter. Turkish Angora (a few colors, including a variety of sea foam greens to emerald).Sphynx (a variety of colors, including pale green to hunter green).
Norwegian Forest Cat (anywhere from a mossy tint to deep pine).Abyssinian (a few colors, including a range of greens).This is not to be confused with Sectoral Heterochromia, which is when the iris has different colors within the same iris. Alos also has bi-colored eyes, which is scientifically known as Heterochromia Iridis. Odd-eyed cats, aka cats with two different eye colors, often sport a green eye and a blue eye, like Venus, the two-faced cat. Some of the most famous cats on the internet boast a green eye.

In people, only about 2% of the population are believed to have green eyes. And, of course, domestication brings along selective breeding and, with it, a broader range of cat coloration – including coats and eyes. Carmen Blázquez and Ismael Galván, in their abstract, Intraspecific eye color variability in birds and mammals: a recent evolutionary event exclusive to humans and domestic animals, most wild animals have a very limited eye color available within a species. That’s right somewhere in the domestication process of kitties sprang a rainbow-like range of eye colors. One interesting facet regarding the variety of colors that cat’s eyes possess comes from the most unlikely of sources: humans. Melanocytes, also found in the iris, control the color (the more there is, the darker the eyes will be). The more melanin, the more intense the color. The color is determined by two variables: hue and intensity. Basically it’s all cellular: melanin and melanocyte activity. The color of a cat’s eyes has to do with a few factors within the iris.
