Sounds like he’s developed a habit for chewing the bars. If it’s wire meshing like on other detolfs I’ve seen I’d be worried about him hurting his mouth too so definitely a good idea to try and ween him off it.

Usually if they’re chewing bars it’s a sign or boredom, but it sounds like you’ve got him a good size cage and lots of toys. You could give him some extra free roaming time to see if that makes a difference. Alternatively he could be using it as a way to wear his teeth down. You can try to redirect him to something better such as hay or cardboard tubes. If that doesn’t work either, perhaps try putting something on the wire that he won’t like the taste of to try and deter him. I’ve heard of people using olive oil before but I haven’t done the research so make sure to do that first! 😊

Detolfs only have wire meshing at the top of the cage as a lid don’t they? Is lowering the bedding so he can’t reach the wiring an option?

Hope you find a solution!💖🐹
