Kittens usually open their eyes fully around 15 days after birth, but it takes about a month for them to be able to walk normally.
A kitten's growth and development are influenced by factors such as breed, individual temperament, environment, and nutrition, so the specific timing may vary. When a kitten opens its eyes, they are initially just a slit, gradually opening wider over time. During this stage, owners should never pry open the kitten's eyes with their hands, as this could cause injury.
Furthermore, kittens need time to develop their bones and muscles, so letting them walk on their own too early may damage their bones and muscles. Therefore, when caring for kittens, it is important to follow their growth and development patterns and avoid excessive intervention or forcing them.
