Absolutely! At least in most cases I would think, theres always the exception!
Nibbles refuses to come OUT of his ball when he's in it, I'll open it up and try to encourage him to come out but he'll just turn the opposite direction and press as hard as he can to go the other way and roll! He seems to remember his way around the house because when I put him down it doesn't take him long for him to work his way into our bathroom at the other end of the house! (I leave all the doors open for him!). He can see the furniture (I have a clear ball, I think they're better so they can see out more) and he works his way around the furniture, around the door frames, from one room to another!
He loves it.
