when do kittens open their eyes

Kittens typically begin to open their eyes when they are around 7 to 14 days old. The process starts gradually, with their eyes initially opening as a small slit or gap, eventually becoming fully open by about 2 weeks of age. However, this timeline can vary from kitten to kitten, with some opening their eyes as early as 7 days and others taking up to 16 days. At birth, kittens' eyes are tightly closed to protect their delicate developing eyes, and their vision continues to develop after their eyes open. Usually, their eyes are fully open and starting to focus by about 3 weeks old. The initial eye color is often blue but may change as the kitten grows older, around 6 to 8 weeks of age.
