As a devoted cat owner, you likely cherish every detail about your feline companion, including their captivating eyes. If you’ve noticed a change in your cat’s eye color, it can be a cause for curiosity and perhaps even concern. Understanding why this happens is crucial for ensuring your cat’s well-being and addressing any potential underlying issues.
Why Do Cat Eye Colors Change?
While some cats retain the same eye color throughout their lives, others experience changes, particularly during their kittenhood. This is a natural process influenced by genetics, age, and even health conditions. Let’s delve into the common reasons behind these fascinating transformations.
Kittenhood and Eye Color Development
Kittens are often born with blue eyes, which gradually change color as they mature. This transformation is driven by the production of melanin, a pigment responsible for eye color in both humans and animals. As kittens grow, their melanin levels increase, leading to a shift in eye color to shades of green, gold, copper, or even amber.
Genetic Predisposition
Just like humans, cats inherit their eye color from their parents. Certain breeds are known for specific eye colors, while others exhibit a wider range of possibilities. For example, Siamese cats typically have blue eyes, while Persians can have a variety of colors, including green, blue, and copper.
Health Conditions
In some cases, a change in eye color can be a sign of an underlying health issue. Conditions like glaucoma, uveitis, or even certain infections can affect the pigmentation of the iris, leading to color changes. If you notice any other symptoms alongside a change in eye color, such as redness, cloudiness, or discharge, it’s essential to consult your veterinarian.

Kittenhood and Eye Color Development
Kittens are born with blue eyes, regardless of their breed or expected adult eye color. This is because their irises, the colored part of the eye, haven’t fully developed yet. As they grow, the melanin pigment responsible for eye color gradually increases, leading to a change in eye color. This process typically takes several weeks to months, and the final eye color is usually established by the time a kitten reaches six months of age.
Factors Influencing Eye Color in Kittens
- Genetics: The primary factor determining a kitten’s eye color is its genes, inherited from its parents.
- Breed: Certain breeds are predisposed to specific eye colors. For example, Siamese cats are known for their striking blue eyes, while Persians often have green or copper eyes.
- Melanin Production: The amount of melanin produced by the iris determines the intensity and shade of eye color.
Changes in Eye Color During Adulthood
While most eye color changes occur during kittenhood, some cats may experience subtle shifts in eye color as they age. These changes are usually gradual and can be influenced by several factors:
1. Health Conditions
Certain health conditions can affect eye color. For instance, cataracts, a clouding of the lens, can make a cat’s eyes appear cloudy or discolored. Other conditions, such as glaucoma, can cause changes in the shape of the iris, leading to alterations in eye color.
2. Medications
Some medications, particularly those used to treat eye conditions, can temporarily change a cat’s eye color. It’s essential to consult with your veterinarian if you notice any sudden or unusual changes in your cat’s eyes after starting a new medication.
3. Nutritional Deficiencies
While rare, nutritional deficiencies can sometimes contribute to eye color changes. A balanced diet that provides all the necessary nutrients is crucial for maintaining your cat’s overall health, including eye health.
When to Consult a Veterinarian
Most eye color changes in cats are benign and don’t require veterinary attention. However, it’s important to consult with your veterinarian if you notice any of the following: (See Also: Cats Who Got Stung By Bees)

Recap
A cat’s eye color can change throughout its life, primarily during kittenhood as melanin develops. While some changes are normal, sudden or drastic shifts, along with other symptoms, may warrant a visit to the veterinarian. Understanding the factors that influence eye color and recognizing potential health concerns can help you provide the best possible care for your feline companion.
Why Did My Cat’s Eye Color Change?
My kitten’s eyes were blue, but now they’re changing to green. Is this normal?
Yes, it’s very common for kittens to have blue eyes when they are born, and then for their eye color to change as they mature. This is because the pigment in their irises develops over time. By the time they are around 6 months old, their eye color should be fully developed.
My cat’s eyes used to be green, but now they seem more yellow. What could be causing this?
A change in eye color to a more yellow hue could be a sign of aging. As cats get older, their eye color can sometimes lighten or become more amber. It’s also possible that your cat’s diet or health condition could be contributing to the change.
Can stress or illness cause a cat’s eye color to change?
While stress or illness can affect a cat’s overall health and appearance, they are not typically known to cause significant changes in eye color. However, if you notice a sudden or drastic change in your cat’s eye color along with other symptoms like lethargy, loss of appetite, or discharge, it’s important to consult with your veterinarian.

My cat has heterochromia, meaning they have two different colored eyes. Can this change over time?
Heterochromia is a genetic condition, and the eye colors are usually set at birth. While it’s possible for the shades of the different eye colors to slightly lighten or darken over time, the overall pattern is unlikely to change.
My cat’s eye color seems to change in different lighting. Is this normal?
Yes, just like human eyes, a cat’s eye color can appear to change depending on the lighting conditions. The amount of light reflecting off the iris can affect how we perceive the color.
