Well, yes, some carnivorous plants do eat animals like in the Little Shop of Horrors.
Carnivorous plants that eat insects have been known, on rare occasions, to eat tiny amphibians and baby fish that inadvertently land within their jaws.
However, if you’re looking for a giant plant that eats big mammals or something, I’m afraid you’ll have to stick to the shelves at your local video store.
Or rent Little Shop of Horrors. It’s a classic.
