You will need to keep a watch on him at all times as he may start to chew things :lol: :lol: Also, if he has the lead on he could become tangled up, so again keep an eye on him.
He might hide under chairs etc as if you have only had him a short time, he is still not used to you and placing him in more different surroundings might unnerve him a bit. If he does, just let him take his time and see if he wants to come out.
Also, will you have lots of people around esp children. If so, then I wouldn't recommend doing it.
One last thing - be prepared for a few bunny raisins to be left around and there might be the occasional wee, esp if he is a bit scared.
