I sayit is a racoon who is the culprit. You seen them and that to me is unusual... like chickbea say they have little hands not only in the front but on thier back legs as well. They are very strong, they have been known to led full grown hound dogs out into the middle of rivers and then climb on top of them and dround them. BAck before trapping became ilegal my brother used to trapp them and adults weighed sometimes over 60 or 70 lbs. Any get live traps set and if you cant find any call animal control, or the Division of Wild life . And they can bring you some. ( Tahts how I got mine) I posted it here some where, I think it was titled :Good info. from the DOW, i think. They have helped me a lot. And have given us premission to kill Foxes , skunks, coons, coyotes, and any other unproctected species that crawls into the trap. I live out side of city limits but i have fairly close nieghbors. So any thing that is here has figured out how easy it is to find food around humans, and is a risk. So anyway good luck, happy hunting, and hope every thing will get better.
