I bought the car sear before I bought Joey, I really believe in car seats and seat belts; the thought of him flying out the windshield scares me to death. This is the seat we have, it's has wheels on it and fits in a shopping cart so I can take him to those stores that allow pets. It also made a great overnight kennel when he was a puppy; since it's small he was never tempted to pee in it like he did with the bigger kennel.
