Have you ever noticed your cat’s eye color changing? It’s a fascinating phenomenon that many cat owners observe. Why does my cat’s eyes change color?

Kitten Eye Color Change During Development
The Magic of Melanin: Understanding Feline Eye Color
Just like in humans, melanin plays a pivotal role in determining eye color in cats. Melanin is a pigment that gives color to the iris. The amount and type of melanin present determine the final hue. Kittens are born with relatively low levels of melanin, which is why most start with blue eyes. As they grow, melanocytes (melanin-producing cells) become more active, leading to the gradual change in eye color. This process typically begins around a few weeks of age and can continue for several months. Interested in the range of colors? Find out more about what colors do irises come in.
How Kitten Eyes Develop
A kitten’s eye color transformation is a beautiful journey. Initially, the eyes appear a cloudy blue due to the low melanin concentration. Around six to eight weeks, the true eye color begins to emerge. This transition can be subtle, with gradual shifts in shade, or more dramatic, with a complete color change. By the time a kitten reaches three to four months old, its adult eye color is usually established. Find out more about when does a kitten’s eyes change color.
Beyond Kittenhood: Other Reasons for Eye Color Change
While kitten development is the most common reason for eye color change, other factors can contribute to shifts in hue, even in adult cats.
Uveitis: A Cause for Concern
Uveitis, an inflammation of the uvea (the middle layer of the eye), can sometimes cause changes in eye color. This condition requires veterinary attention, so it’s crucial to consult a professional if you notice any unusual eye changes accompanied by redness, discharge, or squinting.
Medications and Eye Color
Certain medications, particularly those containing prostaglandin analogues, can darken the iris. This effect is usually gradual and more noticeable in cats with lighter-colored eyes.
