NASCAR race excitement

There's always some sort of excitement going on at a NASCAR race.  But Sunday it was something that is very rarely seen.  At first it was announced that a cat had run across the track.  It was even caught on camera from Kevin Harvick's onboard camera.  He narrowly misses the animal as it runs in front of him.  It was later discovered that the "cat" was actually a squirrel.  The critter escaped unharmed and the race went on.  Such is the unpredictable nature of a NASCAR race.  squirrel video
