I don’t imagine it would be a major problem though maybe it would let them get one or two easy meals but predators don’t hunt unless they’re hungry. So once they’ve taken down one prey animal they’ll ignore the rest. On a species level it’s probably not a major issue.
As opposed to roads which will kill lots of animals.

It’s odd that above doesn’t know it, I thought its definition was well known and would have had no qualms about using it, I wonder if it’s a regional word now?
