High Five 4evar!!!
I love watching how animals react to mirrors, especially cats. The cat is a funny creature in that it is smart enough to notice it's other self, but not smart enough to realize that it is the cat in the mirror. This usually launches an amazing and repetitive game of high five.
Sometimes the high five games get heated and violence breaks out, but after a couple attacks it is obvious that the mirrored cat has too good of reflexes and can predict the real cat's every move
