Kitten goes for a wild ride on 6 month old baby

We found our new kitty, Bogey, taking a ride in my engine after a 45 min, 80 mph, 90 degree heat ride. He was 3 wks and 6 ozs. Happy and healthy now, he is a very curious 4 1/2 week old kitten. He loves to crawl on and around the baby even after the baby swats him (not purposely of course). Brody just learned to crawl and is 6 months old. He crawls on his back and Brody proceeds to buck him like a Bronco and kitty holds on for dear life. Our 2 yr old boxer, who is Bogey's BFF comes over and try's to lick him off to help! So funny!!
