This discussion is reminding me of the movie I saw this past weekend - "The Tale of Despereaux. A little mouse with big courage." It's great! Not quite as "foodie" as Ratatouille, but I would call it somewhat of a "foodie" movie. And it begins with the banishment of rats in a kingdom that once considered them friends.
As an aside, I saw a mouse in a garbage can earlier today caught the humane way so it could be released back in the wild. It was captured by placing a strip of cardboard halfway off of a counter and a piece of cheese at the end to tip it over to the garbage can resting below. It was such a teeny little mouse.
