Help me out here. When we moved in there was a deep but small hole in the garden. We filled it, loosely, it stayed closed. Thought it was foxes digging, as we have them in the garden a lot.
A couple of days ago the exact same spot was dug out so yesterday I filled the hole and around it with some spare mud we had from planting a tree. But this morning it's freshly dug and it looks like some sort of den or an entry hole more than just digging. But whose?
I've added photos. Bear in mind the soil on the grass is a bit of red herring as I was trying to level the ground around it. Size 6 shoe for scale
