I would also recommend using more enclosed hides than the cut in half bark logs if your still using those. something that has one entrance just big enough for him/her to get through and isnt much bigger than they are when wrapped up.
i bought a plastic dog bowl for three bucks and cut a small hole in one side, then sanded down the edges where I cut it so it wasn't sharp.
the dollar tree has better hide options than any pet store I know and for just a buck lol.
