Thanks Jerry and Randall. I saw one today 2 houses down going across the street. I am patiently waiting for him, although I think they have a similarly sized shed that's probably in better shape than mine. I think I am going to fix up the shed so that I can attract more G-hogs and get them to leave the neighbors'
Thanks guys! Did you notice how chewed up the shed is, especially the 3 closest to the burrow entrance? They sharpen their teeth on it to keep them from growing. This is why they prefer to live under a wooden structure.
BTW, I do recall reading about the non-stop teeth growing, also something about if they're not allowed anything to gnaw, their front teeth can grow right through their lower jaws...
