The smaller scraped up areas that are starting to appear without witnessing any activity really has me leaning towards a skunk doing its thing at night. I don't think it is living there, just trying to feed. So the question becomes what to do about it, if anything. I am inclined to just let it be for now. I have a backyard landscape redesign project about to get started and the area where the holes are located is going to become a mulch bed with 3 hemlock trees planted. So, it is going to get dug up within a week or so hopefully.
