Lewis was born with sugar and adrenaline in his blood. There will be times were he will lay down so calmly and peaceful then all of a sudden his eyes will get super wide. And when that happens he goes absolutely insane! I wish I would have somehow recorded this but he saw a fly on the wall. And it was a good four feet or so high. He got a running start, jumped and basically ran up the wall. Unfortunately he didn't catch the fly but my goodness!
