This is something that Wyot started a few days ago. He has traveled with us everywhere in the car, and never noticed anything outside except when we were stopped, and then he would just stare at people and activity...but then, we were driving, and all of a sudden, I hear a dull thud....I look back, and I see him tracking cars as they are coming down the road on the opposite side, and trying to chase them, only to slam into the headrest!!!!!!!!!! I thought he was hurt, but NOOOOOOO!! He kept doing it, but now, he was mindful of the headrest, and tried to slip in between the headrest and the window, obviously without any success, but OMG, I just died laughing!! No more trying to climb into the front on my lap (which I didn't allow, as he has gotten too big, and is a distraction to the driver).
He now stands at attention in the middle of the back seat, staring out at the road in front, just WAITING for the next car to drive by! His tail wags like crazy, and it is just as if he has exercised outside...he's pooped after a trip of doing this, LOL!
