Kittens typically begin to open their eyes between 7 and 14 days after birth. This process can take a few days to complete, and by around three weeks, their eyes are usually fully open
. Some sources note a broader range, with kittens starting to open their eyes anywhere from 2 to 16 days old, depending on individual development
. At birth, kittens' eyes are closed to protect them from infection and damage. The initial opening often appears as a small slit or gap, which gradually widens over several days. When kittens first open their eyes, their vision is not fully developed, and their eyes typically appear blue. The eye color will change over the following weeks, usually settling by about 8 weeks of age
. If a kitten's eyes have not opened by three weeks of age or if there is excessive discharge or crusting preventing the eyes from opening, it may indicate an infection or other health issue, and veterinary advice should be sought
. In summary:
- Kittens open their eyes between about 7 to 14 days, sometimes as early as 2 days or as late as 16 days.
- The opening is gradual and can take several days.
- Eyes are fully open by around 3 weeks.
- Initial eye color is blue, changing by 6-8 weeks.
- Delayed opening beyond 3 weeks or eye discharge warrants veterinary attention.
