Siamese cats have unique eye colorings due to a gene mutation that affects the production of melanin, which gives color to their fur and eyes. Siamese cats can have dark blue, green, yellow-green, or gold eyes depending on how much melanin is produced by the body.
The amount of melanin in a Siamese cat’s eyes may change over time because of environmental influences such as stress and exposure to sunlight. Other factors, such as illness, can also lead to changes in eye color.

While this isn’t necessarily causing concern if your cat’s eyes are changing shades, it’s always best to consult with your veterinarian if you notice any sudden or dramatic shifts in the shadow of your cat’s eyes.Â
With proper care and regular checkups, your Siamese cat’s eyes can remain in optimum condition for as long as possible.

At what age do Siamese cats’ eyes change color?
Siamese cats are known for their distinctive, bright blue eyes, but when do those eye colors begin to change? Siamese cats typically see their eyes change color as they enter adolescence. This process usually starts between 3-8 weeks of age and is completed by the time they reach four months old.
At birth, all Siamese kittens will have dark blue eyes. Then, as they age, the pigment in their coats begins to break down, leaving behind patches of white or light fur around the ears, muzzle, and tail.
As this happens, the eye color changes from dark blue to a lighter blue or even green and gold. Depending on the cat’s genetics, this color change can take anywhere from 8 weeks to 4 months.
Once they reach adulthood, a Siamese cat’s eye color will generally remain unchanged unless the fur around their eyes fades, resulting in a lightening of their colored irises. Sometimes, a cat’s eye color gradually shifts over time, becoming lighter or darker depending on their sun exposure.

Why do Siamese cat eyes turn red?
Siamese cats have a unique and recognizable look with their almond-shaped eyes, pointed coat pattern, and distinctive blue-gray color. One of the fascinating aspects of these cats is their bright red eyes. Depending on the individual cat’s genetics, this eye color can vary from light pink to deep crimson. But why do Siamese cats’ eyes turn red?
The answer lies in the cats’ genetics. Siamese cats are genetically predisposed to having white coats and blue eyes, which is why they often have this combination. However, the gene that determines eye color also affects how much pigment accumulates in their irises.
When there’s too much pigment, it dilates the blood vessels of the eye and causes them to appear red. This phenomenon is known as “hyperemia,” It can be seen in other animals, such as horses and dogs.
In addition to genetics, Siamese cats may also have red eyes if they are experiencing stress or illness. The redness can also be caused by an infection, allergies, or even a reaction to certain medications. If your Siamese cat’s eyes have suddenly become red and you’re concerned about their health, it’s essential to take them for a checkup with the vet.
Ultimately, red eyes in Siamese cats are typically hereditary and nothing to be concerned about. However, if the color change appears suddenly or is accompanied by other symptoms, it’s essential to have your cat checked out. His eyes lack pigment, thus color from the environment can reflect back into them and change their color. With proper care and attention, you can help ensure that your Siamese cat has bright and healthy eyes.
