Why Do So Many Cats Have Green Eyes?
Fur Color Has Nothing To Do With It – While we’re talking about cool cats with green eyes, we can’t forget about Cattitude Daily’s own Pepper and Mr. Purple. These two adopted cat brothers are also great examples of how fur color has nothing to do with eye color. 
Pepper (left) and Mr. Purple (right) You’d think that because melanin is responsible for both eye and coat color, the two traits would be linked. But that’s not the case. The melanin in a cat’s iris is separate from the melanin in its fur. This means any colored cat can have green eyes.
While Pepper is a tuxedo cat and has large areas of black fur that relate to the highest level of melanin, his green eyes indicate his irises have low levels of melanocyte activity. Mr. Purple’s eyes are a similar color to Pepper’s, but his gorgeous mane of ginger floof is obviously completely different than the dapper black and white of his tuxie brother.
The difference in their coat colors has nothing to do with their similar green eyes. Cats of all colors and personalities can have green eyes, and it’s safe to say they’re all gorgeous. Does your cat have green eyes? We’d love to see it! Post a picture in the comments.
Is it rare for cats to have green eyes?
In honor of St. Catrick’s Day (how could we not?), we’re highlighting some of our favorite felines of the green-eyed variety. Simply put, green-eyed cats are good luck because all cats are good luck! But you may be wondering where exactly those entrancing emerald peepers come from? Let’s take a look at some of the interesting facts about cat eye color. 
A cat’s eye color is determined by the amount and intensity of pigmentation that is in the front and rear of the iris. The evolution of your cat’s eye color may be similar to your own: Just like some people, cats are born with blue eyes that usually change to another color as they mature and develop pigmentation. 
Unlike people, however, a cat’s irises will not typically become brown. The darkest color you’ll see on your feline friend is copper, barring the result of a medical issue or injury. White cats with blue, green, or orange eyes are not albino, despite what you may have heard. Like other animals, true albino cats have pink or bluish-pink eyes. 
Eye color is often related to breed, but not necessarily to coat color. For example, purebred Russian Blue cats have vivid green eyes; yet many cats with identical, plush gray-blue fur have golden-yellow or amber eyes. (Equally striking, if you ask us.) This means these latter cats are not “purebred” Russian Blues. 
Pedigreed cats usually have more intense eye colors: There’s the bright copper of the Bombay, the stunning turquoise of the Tonkinese, and the gooseberry green of the Egyptian mau, to name a few. Green-eyed cats are relatively common; and cats with eyes with shades of green have become common in random-bred cats (called moggies). 
The luckiest cat of all? The “odd-eyed” kitty with two different eye colors! Again, these cats tend to have white or mostly white fur. This mutation is more common than you’d guess — and far more common in cats than in humans. Rarer is “dichroic” or dichromatic eyes, which results in having two colors in one iris.
Does every cat have green eyes?
What’s The Most Common Color for a Cat’s Eyes? – You’d think that would be the most common color found in a cat’s eyes, but it isn’t. Actually, yellowish gold is considered to be the most common.

Why do cats rarely have brown eyes?
It’s All About Melanin – 
The pigment produced by the melanocytes is called melanin. A while back I wrote an article on the genetics of cat fur color, in which I explained that melanin plays an important role in determining how dark your cat’s fur coat will be. The same thing is true with cats’ eyes: The more melanocytes there are in your cat’s irises, the darker their color will be.
