Did you know all kittens are born with blue eyes? Their true color only reveals itself as they mature.

1. Why Are Kitten Eyes Blue?

Newborn kittens lack melanin, the pigment that gives color. As they grow (around 6-8 weeks), melanin production ramps up, and their eyes change to green, yellow, orange, or remain blue.

2. Rare Eye Colors

Copper and odd-eyes (heterochromia) are rare and stunning. Heterochromia is often found in white cats.

3. Eye Color and Health

Sudden changes in an adult cat's eye color can signal health issues like uveitis or glaucoma. Always consult a vet if you notice changes.
