The thread about the mouse chewing through a coffee bag made me wonder... I keep things in the large pantry in our wash room, and on a large open shelf. I know mice could easily chew through the plastic bags some items are in. I have always heard that mice will chew through plastic 5 gal. buckets too, but have never seen this firsthand. My question-- for those of you who have had mice chew through plastic buckets, can you give some idea of how thick the plastic was? And where on the bucket it chewed--on the side at the bottom or on the lid? I have some 24 lb. icing buckets from the local grocery store deli, and the plastic is (obviously) food grade, lids snap down tight, and there is a little foam gasket in the lid to form a tight seal. The plastic seems to be a little thicker than the 5 gal. white buckets I've gotten from Wal Mart (paint dept) and Home Depot.
