I just watched your cage cleaning vid, cool toys btw, he must love those! I was wondering how often you do that & if you always remove all the substrate?
If you do that's probably making him more stressed & nervous, you really only need to remove a little of the substrate at any one time, maybe a third every two to three weeks or even less if he uses the litter tray/sand bath to pee in, if you clean out his nest & or hoard it's best to put at least some of it back too.
If you do that you would save a lot on substrate & he would probably be a much more relaxed little man! If you could I'd give him some deeper substrate at least in one bin so he can have a really good burrow!
