After chewing his bars this morning I gave him access to his tubes and he loved them, although he did start taking food and bedding up there, however, I wasn't worried....
BECAUSE.....
Previous to this he scared the life out of me when I couldnt find him in his cage and then I checked in his hamster head house which he has never touched and found him sleeping peacefully in it.....Even after I gave him the tubes back he was not interested in sleeping in them....
TOUGH LOVE DOES WORK!
