Cat eye colors are captivating, but besides admiring them, owners should also pay attention to sudden color changes, cloudiness, increased discharge, or abnormal pupils.

Cat eye colors are related to melanin, breed, and age, with common colors including yellow, green, blue, and amber. This article covers 7 types of cat eye colors and important health observations.

Key takeaways

• A cat's eye color is determined by the amount and activity of melanocytes in the iris. Less melanin results in blue-green hues, while more melanin leads to darker shades like yellow, brown, or copper.
• Most kittens are born with blue eyes because the melanin in their irises hasn't fully developed. Their eye color typically stabilizes around 3 months of age.
• Amber is the most common feline eye color, while 'heterochromia' (two different colored eyes) or 'sectoral heterochromia' (two colors within the same iris) is the rarest.
• Excessive yellowish-green or rusty discharge, redness and bloodshot whites, frequent blinking, light sensitivity, abnormal pupil size, or cloudy eyeballs are all warning signs of eye problems.

Why Are Cat Eye Colors So Varied?

It all comes down to the amount and activity of "melanocytes" in the iris of a cat's eyes. Simply put:

• Less Melanin: When light passes through and refracts, it produces blue light, making the eye color lean towards blue and green hues.
• More Melanin: Light is absorbed, resulting in eye colors leaning towards deeper shades like yellow, brown, and copper.

Most kittens are born with blue eyes because the melanin in their irises hasn't fully developed yet. Around 3 months of age, their eye color gradually settles.
