Didn't they just burrow UNDER the fence? They are groundhogs, after all.

The way you get rid of moles is to kill all the grubs in your lawn. You kill grubs with poison. I wouldn't want to do that so I let the cats dispatch the moles as they find them (couldn't stop them anyway). Okay, to avoid snarky comments, I really just don't do anything about the moles, and sometimes the cats catch them.

What do woodchucks/groundhogs eat? Take away their food supply.
