Is it normal for your cat’s eyes to change color?
It is normal for kittens’ eyes to change color until they are around 8 to 10 weeks old. This is because cats are born with relatively little melanin in their eyes. As their melanocytes begin to activate, their irises will develop more melanin, changing color.
It’s essential to consider your cat’s age when trying to determine if it’s normal for your cat’s eyes to change color. It is also essential to think about the color of your cat’s eyes.
This is why most kittens are born with blue eyes. they have almost no melanin in their eyes when they are born.
However, as your cat ages, it’s not normal for their eyes to change color. There is however an exception, cats with yellow/green eyes can see as if their eyes were changing color slightly. This is because this particular coloring is more sensitive to light for our eyes so it may look like your cat’s eyes are more yellow or green depending on the lighting.

Sudden changes can be the most concerning. If your cat’s eyes are changing overnight or after a few hours, chances are she needs medical attention.
5 reasons why your cat’s eyes are changing color
Outside of a growing kitten, the reasons for eye color changes are usually quite negative. So take a deep breath, remember this article is not meant to help diagnose your cat. Instead, if you’re concerned that your cat’s eyes are changing color and he may have an underlying health condition causing the problem, take him to the vet.
Your veterinarian will be able to make suggestions, including possible treatments and things that can help prevent the problem from happening again.
Your cat has uveitis
Uveitis is relatively common and results from inflammation of the uveal tract in your cat’s eye. It can affect one or both eyes. Although the uveal tract in your cat’s eyes may become inflamed on their own, it’s more likely that there is an irritating underlying medical condition.
Common causes include bacterial infections, eye trauma from scratching or hard impact, viral illnesses, high blood pressure, and other causes. In some cases, uveitis can be a sign of metastatic tumors and other serious conditions, but usually it’s more common.
High blood pressure affects your cat
We’ve already mentioned high blood pressure as a possible cause of uveitis, but it’s important to note that high blood pressure can change the appearance of your cat’s eyes.
Dealing with high blood pressure is essential as it can lead to further eye damage and uveitis. Left alone for too long, the high pressure can cause permanent damage to your cat’s eyes as well as other health issues.
Your cat has glaucoma
Glaucoma can happen to cats just as it happens to humans. Like humans, glaucoma in cats is caused by excessive pressure inside your cat’s eyes. This can make your cat’s eyes cloudy over time.
Advanced glaucoma can cause your cat’s eyes to turn cloudy blue or milky white. It can affect their eyesight and can also be a possible cause of uveitis.
Glaucoma is serious, so it’s essential to have your cat evaluated by a veterinarian as soon as you see symptoms.
Portosystemic Liver Shunts in Cats
If your cat’s eyes are beginning to turn a copper color, it may be a sign that your cat has a portosystemic liver shunt. These abnormal growths create a bridge in your cat’s intestines that allows food and nutrients to bypass the liver during digestion.
Bypassing the liver can allow for above average toxin buildup, which in turn can cause liver damage. As it is a genetic defect, most cats that display copper eye color will already have it when you adopt them.
However, the copper color may develop later in your cat’s life. There are also rare instances where your cat may develop a portosystemic liver shunt later in life, usually when their liver is already stressed.
Some breeders breed for this trait as the copper coloration can be exotic; Unfortunately, breeding this way doesn’t take the health of the cat into consideration, and these cats may need expensive treatments to keep them healthy and happy.
Portosystemic liver shunts, or PSS, can be managed with a combination of diet and medication in some cases. Other times, your vet may recommend surgery to minimize the effects of PSS and give your cat more daily life.
In addition to the causes we have already mentioned, adult cats can experience changes in their eye color due to various bacterial infections in their eyes. Usually these infections can be treated, but it’s essential to get your cat to an infection vet as soon as possible, as the symptoms will likely get worse over time.
In the worst case scenario, your cat may have permanent damage from persistent eye infections if not treated quickly.
Why One of My Cat’s Eyes Changed Color
If one of your cat’s eyes is a different color than the other eye, then congratulations! Your cat has heterochromia or genetically different colored eyes.
However, suppose you know that your cat is not it have heterochromia, or their eye turns an abnormal color such as dark black or reddish. In this case, your cat is more likely to have an eye infection or other medical condition.
Cloudy eyes can also be a cause for concern, even if your cat’s eye color hasn’t changed.
Do cats eyes change color at night?
Technically, no, your cat’s eyes don’t change color at night. However, since cats have relatively good night vision, their eyes can look very different at night. This is because the part of your cat’s eye that gives it good night vision is reflective. When light reflects through your cat’s eye, it may appear that the iris is a different color or that it has glowing eyes with no iris or pupil.
Rest assured, though, your cat will still have the same color eyes if you turn on a light.
Do cats eyes change color as they age?
Yes and no. Your cat’s eye color shouldn’t change much over time, except when she’s a kitten until she’s about three months old. This means that your kitten’s eyes may change, but an adult cat’s eyes will generally remain the same primary color as they age.
Don’t worry too much about slight shade changes as your cat ages. It’s a bit like people’s eyes. The overall color remains the same, but the exact shade and color detail may change slightly over time.
Why did my cat’s eye turn black
Most often, if your cat’s eyes have turned black, they are reacting to low light conditions. Your cat’s irises can expand and contract on their own to help her see better. Cats will naturally open their iris wider so that their pupil receives more light, improving their sight at night.
Sometimes the cat’s pupils dilate even in light that seems bright to people or because they are happy or sleepy at the time.
However, there is also a rarer cause of black eyes. Iris melanosis may be to blame if your cat’s eyes seem to darken over time, even when their pupils are small and contained. Iris melanosis is an overgrowth of melanin in your cat’s eyes and begins as a small spot of excess melanin and progresses over time.
Fortunately, iris melanosis himself is a benign condition. However, it can progress to a malignant condition, so cats with iris melanosis should be carefully monitored by their veterinarian to ensure their eyes are healthy.
