Bet you never had this in your air filter!!

Well now, if you were a squirrel, and you found this nice warm, safe, insulated, place to spend the winter ... would you not want to bring your snacks with you?

My only question is: Either you have a huge air-filter that can fit a squirrel, a very strong mouse that can carry the candy bar, or very small squirrel ... which? Lettus snow when you see him.
