When is it okay to let the kittens wander????

My kittens have opened their eyes and are starting to be slightly more active. When is a good time to make the nesting box so that they can get out and wander around the room a little. Right now they are like about a week and a half. The box they are in right now has 7 inch walls on it and the kittens are strong enough or big enough to get out. Should I shorten a side to about 3 or 4 inches or wait like another week or so???

If they've only just opened their eyes, they need to be in the nest for a bit longer, especially so they can stay warm as, at this stage, they will have trouble maintaining their own body temperature. Are the kittens with mum-cat or being hand-raised? If they're with mumcat, she will keep and eye on them and retrieve any escapees. If they're being hand-raised, you need to keep them in a box that they cannot get out of. That way, short play sessions on a clean floor (when they're at least 3 weeks old) can be determined by you and you don't run the risk of escapee kittens becoming chilled or lost.

Cool thank you very much

Can we see some pics of your cute little darlings??

I kept mine in a tokeyo cage where mom could leave any time, but the kits couldn't till they were big enough to get over the door. That was about 3-4 weeks old. Problem was they'd get out but still too little to climb back in.

By the time they were about 6-8 weeks old they could get in and out of the cage by themselves.
