How long new born kitten open their eyes?

Newborn kittens are born with their eyes closed. Their eyelids are fused shut and will gradually begin to open between 7 and 10 days of age. Both eyes usually open at the same time. The opening of their eyes is a gradual process, and it may take several days for them to fully open.

Here is a day-by-day breakdown of when kittens typically open their eyes:

- Day 1-6: The kitten's eyes are closed.

- Day 7-10: The kitten's eyes start to open, first appearing as a small slit.

- Day 14: Kittens' eyes are usually fully open.

If your kitten's eyes have not opened by 14 days of age, it is important to consult a veterinarian as there could be an underlying medical condition.
