Have you ever asked yourself “do all kittens have blue eyes”? Well, technically yes. All kittens are born with blue eyes. 

But their eye color starts to change when they’re about six years old. This is right about when melanin starts producing in their irises. But can kittens have blue eyes permanently? Also, why don’t all kittens have blue eyes forever? Those are things that we’ll find out in this guide. 

Are All Kittens Born With Blue Eyes?

Yes, all kittens are born with blue eyes. But it’s rare for kittens to have a blue eye color as adult cats. Only a few of them retain their blue eye color as they age. The eye color of other kittens changes to default as they turn about six weeks old, which is when they develop eye pigmentation. These default colors include yellow, amber, and hazel. 

Cats with blue eyes don’t have melanin in their irises, causing the irises to be clear. As a result, the blood vessels inside the eyes are visible, leading to blue eye color. Moreover, kittens with blue eyes also tend to have white coats due to a lack of pigmentation in their skin. Such kittens are termed albino kittens or cats. 

Many people think kittens with blue eyes are prone to medical problems. The truth is that blue or any other eye color doesn’t, in itself, indicate health issues in kittens. With that said, cats with blue eyes often have white coats. And white colored coats are often associated with hearing problems in cats.

According to an article published in the Cornell Feline Health Center, over 65 to 85 percent of white cats with blue eyes are deaf. But some of these cats are only deaf in one ear. Additionally, the article mentions that if a white cat with one blue eye has hearing loss in one ear, the affected ear will be located on the same side as the blue eye.

When Does a Kitten’s Eye Color Change?

Generally speaking, a kitten’s eye color changes between 4-8 weeks of age. The age at which a kitten’s eye color changes varies from kitten to kitten. Some kittens are born with a permanent eye color, like blue-colored eyes. 

On the flip side, others tend to have their eye color change within a few months or up to a year. Moreover, the color-changing process will be complete by the time your kitten becomes three months of age. This makes it a bit tricky as the owner to judge what your kitten’s final adult eye color would be. However, isn’t that part of the fun as well?

The new eye color of kittens is usually permanent and stays with them for life. But some kittens keep changing their eye color gradually during the first year of life due to the production of melanin. Some kittens may even experience changes in eye color later in life due to certain diseases or medical conditions, such as eye trauma

Should I Worry If My Cat’s Eye Color Doesn’t Change? 

If your cat’s eye color doesn’t change, it’s generally nothing to worry about. The amount and type of melanin determine eye color in the iris. Some kittens are born with a particular eye color that remains relatively consistent throughout their lives, while others may experience changes in eye color as they age.

If you have a kitten with a specific eye color that does not change, this is likely normal for that kitten and breed. For instance, Siamese and Himalayan kittens tend to have blue eyes forever. Still, you can visit a vet to ensure there’s no underlying issue. Your vet will take a detailed exam of your cat and come to the conclusion of whether or not it has any visual or auditory problems. Even though this might feel like an unnecessary step if your cat is not displaying any symptoms of poor eyesight or hearing, sometimes visiting the vet just for some mental satisfaction can be a good thing.

While lack of eye color change is not something to worry about, you should be concerned if your kitten’s eye color reverts to blue. It can indicate a visual disturbance with your kitten, such as blindness. If it happens with your cat, visit a vet as soon as possible.
