I travel from Michigan to Florida and back every year. Two eleven hour days. We take all three pets with us and everyone does fine. Magic used to get car sick until I hit on the no feeding thing. She still doesn't LIKE the ride but hasn't thrown up at all in the last few long rides. I desensitize her by taking her on short trips a week or so before we do the long haul and that seems to help. Whenever we stop for potty breaks or just to stretch our legs during the trip we offer them water and I feed her a few dry kibble from my hand never more than a dozen pieces at a time. It's working great.
