Here's a breakdown:
* At birth: Kittens are born with closed eyes.
* Around 10 days old: Their eyes open, but they are blurry and can only see light and dark.
* Around 4-6 weeks old: The tapetum lucidum starts working, and their night vision improves significantly.
So while they might be able to see in dim light, baby kittens are quite reliant on their other senses like smell and hearing to navigate their world at night.
