A police officer has a new sidekick after he rescued a kitten from the middle of a highway. Once inside the patrol car, the feline accidentally set off the siren before snuggling up to its new buddy. The cop's family ended up adopting the cat, who's not the only animal to get into some mischief on the highway. In Arizona, authorities chased loose dogs for about an hour before finally catching them, while in Canada a mother duck stopped traffic to escort her family across the road.
