Can hamsters chew on staples

Hamsters will chew on anything. Some hamsters are chewers and others are not interested. They will chew on plastic, wood, metal and pretty much anything else if they want to. They need to chew to keep their incisors down as they grow. I've seen some pretty crazy chewing and I've yet to have seen a hamster break his teeth. Try some chews toys if you have a chewer. Little non-flavored Milkbones are always a favourite.
