i traveled with my cat from dallas to atlanta and back again. i put a harrnas on the cat and a leash on that. buckled the leash with a seat belt. let the cat roam free in the car, slept on me most of the time. put a small shallow pan on one side the the back seat floor and food and water on the other side. he laid around my neck alot and slept in the other seat the rest of the time. we had so much fun. he loved to ride. sure do miss him. he was my best friend.
