This past week I found a number (15-20) of small, shallow holes in my lawn. It looked like some creature had just pulled the grass out by the roots. The grass was spread around the holes, which barely broke the surface of the dirt. Perhaps something was looking for bugs. I don't think it was a mole, as it didn't really dig any of the dirt out, just cleared a small, round circle about two inches across. We have racoons and skunks in the area, but that's all I know of. The yard is fenced, but a small flexible animal can get in. Any idea what the heck is doing this? I've never seen anything like it before. Thanks.
