One-week-old kittens have closed eyes but no umbilical cord. After about 7 days, the ear canals slowly begin to open. Approximately after 8-12 days the eyes will start to open. Never try to pry open a kitten’s eyes; let them open naturally.
You should never force a kitten to open her eyes before she’s ready. Not only could they damage their eyesight for life, but you run the risk of causing an eye infection. Symptoms of eye infections include: swelling and inflammation.
Six day old kitten
After almost a week, the kittens will start to wobble around a bit on their own and their eyes will start to open.
Vets recommend not touching kittens unless you must do so while their eyes are still closed. You can check on them to make sure they are healthy and gaining weight, but try to limit direct physical contact. The kitten’s mother will also tell you how comfortable she is with her babies.
Physical Development: At 3 weeks of age, kittens will have blue eyes and small ears that start pointing upwards, like a miniature cat. The kitten’s vision and hearing will gradually improve. At this age, a kitten’s first teeth will begin to grow.
3-5 weeks: Walking and using the litter box
Around three weeks of age, kittens usually begin to take their first unsteady steps. While initially shaky and uncertain, as their balance improves by week four, they become more confident and eager to explore their surroundings.
They will begin to explore their surroundings more and often play with each other, toys and people. As an important milestone, kittens will start weaning at this age. This means they are slowly beginning to eat solid food, so they no longer have to rely on you or their mother cat to feed them.
