I've had a tortoise for 5 years now (Toby/Toblerone, he goes by either hehe). He has a pen in the corner of my room, with a glass window, sometimes he scratches at it. So, I wonder if he gets bored? I let him out sometimes to have a trot around the room, but when I'm not home, are there any toys or things like that, that could keep him entertained? Thanks!
