Hi, Has anyone any idea who my nocturnal lodger might be? A shallow hole (approx. 20" x 12") appeared under a large conifer. I repeatedly fill it in but it's back in the morning. Yesterday I filled it in and put an upturned pot over it, this morning another hole has been dug next to it. It's obviously an animal, but is using as a bed overnight. I've ruled out foxes, dogs and it's too big for a cat. Any ideas?.
