I have an outbuilding that I keep my canning jars, old furniture, etc. in and lately something has been knocking the jars off the shelves and pooping on the shelves. I know there is a big chicken snake that lives in the shed and if it is him messing on the shelves I don't care cause I'm not scared of him but I wonder if I have some other critter in there that I need to watch out for so I don't get bit. Anybody know what snake poop looks like? Please don't think this is a joke. I'm serious.
