Can Siamese Cats Have Green Eyes – The Myth Explained!

Siamese cats are some of the most well-known and beautiful cats you can get, but many cat owners know that Siamese cats come in many different colors. But what about their eyes? Do Siamese cats come with several different eye colors as they come in several different coat colors? Can Siamese cats have green eyes?

Generally, Siamese cannot have green eyes. Cats who have the Siamese color traits will always have blue eyes. In a few rare cases, Siamese cats have had slightly green-blue eyes due to more pigment in their eyes than normal.

While green eyes are possible for some Siamese cats, it is not likely. It’s very rare and may mean that your cat won’t show their Siamese coloring as much or is a mix of the breed. Here’s what you need to know about Siamese cats’ eyes, whether they can change color, and generally what to expect.

What Color Are Siamese Cat’s Eyes

Siamese cats are born with the genes for a wide variety of eye colors, but if they get the Siamese color gene, they’ll usually appear to have blue eyes. That’s because Siamese coat colors, with darker fur only on their ‘points’ or their paws, nose, ears, and the ends of their tails, are a form of albinism.

Since albinism also affects their eyes, the blue color is the result of tiny amounts of pigments and other particles in their eyes, not their actual eye color genes.

That does mean that some Siamese cats that aren’t as affected by their albinism may be slightly green since green eyes have very little pigment, but most Siamese cats will have blue or whitish eyes.

Do Siamese Cat Eyes Change Color

Generally, Siamese cats eyes do not change color. Siamese cats are the only breed that most of their members will always have blue eyes, which means that their eyes don’t change color much throughout their life.

However, that doesn’t mean that they won’t have slightly different eye colors as they get older. For instance, many Siamese cats have lighter blue eyes as kittens than they do as adults. Some Siamese cats will also have eyes that get paler over time, leading to a whitish-gray look instead of the normal blue.

One theory for this appearance is that when Siamese cats lose their blue eye color, it’s easier for us to see the light reflected from the back of their eyes, which creates the shiny white or gray color.

For the most part, though, your Siamese cat is likely to have blue eyes and to have mostly the same color their whole life.

What Age Do Kitten Eyes Change Color

Kittens are going through many changes all at once as they get older, including their eyes. Almost all kittens are born with blue eyes, but kittens that don’t have the Siamese gene will usually start to show their adult eye color at about seven weeks old.

Siamese cats’ eyes may change what shade of blue they are around the same time, but it’s very rare for them to change green or yellow, and almost impossible for a Siamese cat to have a darker eye color.

Are Cats With Green Eyes Rare

Green eyes are one of the most common colors for cats’ eyes. Green and yellow are the most common across different cat breeds, even though blue eyes are the norm for Siamese cats.

Green eyes might be slightly less common than yellow, but it’s not rare to see a cat with bright green eyes.

What Is The Rarest Eye Color In Cats

The rarest eye color in cats is very rare. Cats usually have lighter eyes, like green and yellow, with some cats darkening to brown. Brown is less common than yellow or green, and even blue eyes are a little more common thanks to the Siamese gene and a few other causes of blue eyes.

However, that doesn’t mean brown eyes are the rarest color in cats.

The rarest color is a red-copper color as dark as brown eyes but can look a lot more intense. Only a few breeds of cat have this color, but it’s only really common among British Shorthair cats.

Any cat that has tabby or solid-coat coloring can have red-copper eyes, but very few do.

Why Do Siamese Cats Have Blue Eyes

Their distinctive form of albinism dictates siamese eye color. Siamese cats have a gene separate from their color genes that stops their skin and eyes from producing pigment above a certain temperature. Since that temperature is lower than your cat’s core temperature, most of your cat’s cells won’t produce pigment. Only the cooler parts of their body do, like their paws and the tips of their tail.

That means that Siamese cats will produce more pigment on average as they get older, but probably never enough to change their eye color. That’s because your cat’s temperature will go down slightly as they age, but their eyes will always need about the same temperature to work.

Things To Consider

Most cat owners know that Siamese cats can have eye problems, but it’s important to mention. While the sight problems for Siamese cats aren’t entirely related to their blue eyes, having blue eyes doesn’t help. Siamese cats may be more sensitive to light than other breeds because such a light eye color doesn’t filter light for them.

Siamese cats can also be prone to losing their sight as they get older, making them harder to care for as seniors.

Most Siamese cats do surprisingly well with limited vision, but it’s still important to make sure your home is as easy to navigate as possible if your Siamese starts to lose their vision.

Regular vet visits to monitor eye health are also crucial for Siamese cats. Thanks to successful breeding efforts, these animals have had recent health improvements for their eyes and vision, but that doesn’t mean that they aren’t more prone to eye problems than other breeds.

Try to make sure your Siamese has easy access to food, water, and comfortable places that are relatively dark and quiet to help support their eye health and keep them happy at the same time.
