Do squirrels eat cabbage

Well, mice have been known to eat bugs like they might in the wild when times are harsh. My gerbil was lost for two days on our patio, eating nothing but bugs, although I'm can't tell you if a mouse would eat a caterpillar (they like mealworms though). I guess it really depends on the mouse: like how big the mouse is, how big the caterpillar is and what the mouse's personality is.
