The color of a cat's eyes is determined by the melanin content in the iris and the reflection of light by the eyeball. First of all, before the cat is 3 months old, the melanin content in the iris is low, so the eyes are blue, which is often called blue film. When the cat grows up and has more melanin, the blue film will fade away. Secondly, the color of a cat’s eyes will also change at night. This is because the cat will reflect the light back when looking at things at night, which is also the reason why the cat has good vision at night. In addition, if you find that your cat's eyes suddenly change color during growth, it may be an eye disease, such as uveitis, and you need to seek medical attention in time.
