Chews metal cage. HELP!!!

[alemargo]

My bunny broke a leg and needs to stay in the cage with limited movement. He is free roaming and hates it there. Chews on the metal wires at night. I'm afraid he will brake his teeth. He is 8 y.o.
Any ideas to help him to break this habit?

Try attaching plain cardboard to the area/side where he is chewing the bars. The cardboard can be zip-tied (or twine) in place. He'll likely chew the cardboard, but then it can be replaced as needed.

I have plastic sheets zip tied to those places where my rabbits like to chew wires.
