Kittens are born with blue eyes, which change color as melanocytes develop around 4–8 weeks. Certain breeds, like Siamese and Ragdolls, retain blue eyes due to low melanocyte levels. Eye color changes aren't used to estimate age; veterinarians rely on tooth development instead.

Context Explanation

But when do kittens’ eyes change color? The transformation typically begins around 3-4 weeks of age, when melanin (the same pigment responsible for skin and fur color) starts to develop in the iris. All kittens will be born with baby blue eyes, which will change to their adult eye color as they age. By one week of age, the kitten should have doubled her birth weight.
