I used to grow vegetables in a garden until the groundhogs showed up. I bought a “humane” box trap, but every time I caught one it would rip out its own claws trying to escape before I could dump the literally bloody critter a few towns over. I have no idea if their claws grow back, probably not. The whole routine was just too depressing so I gave the trap away and had the garden dismantled and plowed under. Now I buy vegetables at the local farmer’s market.
