The wildlife (like hedgehogs) will feel very audited when they get sliced up by a razorblade, run over, and can barely drag themselves off your lawn to bleed out throughout hours of pain. If they don't bleed out, they often end up mutilated, unable to properly eat, walk, etc.

Nice wildlife auditing. Hedgehogs are endangered in lots of areas of the world. Run your robot lawnmower during the day.

If you don't like that mental image, you should feel for the people working at hedgehog rescues
