Ha! I've had plastic garbage cans that had the edges chewed up when they couldn't get into it. Now we have a large heavyduty single can that seems to be wildlife-proof unless it's knocked over by extreme weather. It's the kind that is mechanically emptied into the truck. When I have to put out a second can, it's just a regular garbage can...so I try to put all the edible stuff in the big can if possible and cardboard and other inedibles in the smaller can.
