It is a city pickup bin, so essentially one of those big rolling trash cans with a cover. The squirrels ate a pretty big (squirrel sized) hole through the cover a while back. And we got 20 can of snow yesterday, with freezing rain on top today. I went out to drop some food in and there he was. I guess he got in through the hole and couldn't lift the cover to get out? Ewewrw
Oh and they only pick it up once a month in the winter so that fucker better stay frozen hard.
