Every kitten enters the world with a pair of striking blue peepers. This isn’t a permanent colour—it’s a trick of the light. The blue appears because the iris has no melanin yet, and light scatters off the clear tissue, much like a pale winter sky.
As the kitten grows, typically between six to eight weeks old, melanocytes begin producing pigment. That baby blue fades, and the true colour—green, gold, amber, or copper—slowly emerges. By the time your cat reaches three to six months, the transformation is usually complete.
So next time you see a kitten with those dreamy blue eyes, enjoy the moment. It’s a fleeting Instagram filter that nature applies only once.
