Thanks for the suggestion. He does have a lot of things he can chew on and entertain himself with so it isn't like he is getting bored, as well as having his out of cage time. I think he is the kind of hamster who wants to escape from anything as he does it whenever I put him in his play pen. He doesn't like confined spaces but not a lot I can do about that, haha. I am definitely working on a routine with him but it doesn't always work out due to other commitments which is annoying. Hopefully we get into the swing of things soon. It all messed up over Christmas, haha.
One of the Labyrinth houses does look amazing to have. I might have to look into that further and see what I can do. Thank you for suggesting that!
