Well, rats tend to eat things that are put into their cage. They are very curious little rascals! Wood toys would probably be a safe thing for them to gnaw on. At PetSmart, they have these cool little wood shapes that you can put into their cage. Also, they have this thing called "The Snack Shack". It is a house that they can eat! Hope this helps
