One day Sean Sweat decided he wanted to take his cat on a ride on his motorbike. Inspiration struck when he discovered that his kitty would fit in a giant hamster ball he had found online. However, Sweat thought safety first. He tested the reliability of the ball up to speeds of 140mph, of course without the kitty in it. He said the ball didn’t budge so it made sense to put his cat in it. Credit: YouTube/clanspanker.
