Hedgies can eat peppers, it's if hedgies should eat peppers that's the question. I was thinking more the hot peppers, as that is what came to mind. (I don't eat peppers...) If green peppers are safe (regardless of nutritional value, which I have no clue of) then by all means, go ahead and feed them.
What I was referring to before was the hot peppers, which is why I advised not to feed them.
