When I was sitting at my door the other day this had to be one of the most unreal images that I have ever seen in my life.  A squirrel was actually sitting on the banister of my porch eating what looked like a form of Styrofoam.  It was gnawing and chewing away at a big chunk of it and its little jaws had to be moving at over 20 mph and it took a bite out of the Styrofoam every 2-3 seconds it was an unreal sight.  The way it was looking at me out of the corner of its eye made it seem as though it was going to try and come to attack me but luckily I was taking the picture through glass  LOL
