Glad you are enjoying your new cage Turbo! Is it a hamster heaven? (Ladders with huts at the top!). Our hamster Charlie says bar chewing is bad for your teeth and if you ask your owner nicely they could put deeper substrate in so you can dig some tunnels instead of bar chewing
(If you fill the cage base to almost the top and heap it up in the middle they start pushing the stuff around and love digging tunnels).
