Kitten Eye Color Development
Most kittens are born with blue eyes. This isn’t their true eye color, but rather a lack of melanin, the pigment responsible for eye color. As the kitten grows, melanin production increases, causing the eyes to gradually change to their adult color. This process usually begins around six weeks of age and can take several months, sometimes even years, to complete.
Genetics and Breed Specific Eye Colors
Genetics play a major role in determining a cat’s eye color. Certain breeds are predisposed to specific eye colors. For example, Siamese cats often have striking blue eyes, while Russian Blues are known for their emerald green gaze. do kittens eye color change This genetic predisposition dictates the amount and type of melanin produced, ultimately influencing the final eye color.

- Green: A vibrant and striking color often seen in breeds like Russian Blue and British Shorthair.
- Blue: A classic cat eye color, associated with Siamese and other pointed breeds.
- Gold/Copper: A warm, rich color frequently seen in Abyssinian and Persian cats.
- Hazel: A blend of green and brown, creating a unique and captivating eye color.
- Odd-Eyed: A fascinating phenomenon where a cat has two different colored eyes, often one blue and one green or gold.

“Any sudden change in eye color warrants a veterinary check-up,” says Dr. Emily Carter, DVM, specializing in feline ophthalmology. “While some changes can be benign, it’s always best to rule out any underlying medical conditions.”
Mood and Lighting Effects
While not a true color change, a cat’s eyes can appear to shift hues due to changes in mood or lighting. Pupil dilation, which occurs when a cat is excited, fearful, or in low light, can make the iris appear darker. Conversely, constricted pupils in bright light can make the eye color appear lighter. This phenomenon is similar to how human eyes appear to change color in different lighting conditions.

Do Cats’ Eyes Change Color as They Age?
While less common than kitten eye color development, some cats may experience subtle shifts in eye color as they age. This can be due to a gradual decrease in melanin production or changes in the structure of the iris. These changes are typically gradual and less dramatic than the initial color change seen in kittens.
