my 子猫 are 3 weeks old should i let them roam my apartment(it's 3 1/2 rooms) freely または close them off in a small section

Keep Them In your Bedroom With The Door Closed ?
Thats What I Do

what i would do is make a little house for them out of a cardbord box and decorate it, place it in your room
and put them in there, theres the awser

i have ネコ myself and the we experimented with this kind of situation and we found it was best to keep them contained in one room until they were six weeks old, then we let them roam the whole house on their own and it worked great
