I say it's a rat. Too big to be a mouse. Experts out there? Here is an excellent close up of a good print, even got the foot pad! The same print, but in my boot print. Helps for scale, eh? Here is a hole the little bugger tried to dig; but ran into fence. He has done many such, and they seem to go nowhere. I check em out............. So this is a rat situation, would you say. NB: I am out in the boondocks, not in a town or city. All this activity is strictly NOCTURNAL, also.
