The 18 # avitar cat goes with us most of the time---may leave him home for a weekender with a continuous feeder but take him in our motor home---he really doesn't like the driving part but when we arrive he is fine---when we go north or south he rides fine [sorta] but when we go east ot west he get sick---slobers for a while---then barfs and is ok---asked the vet and he just said 'Oh well, that's Toby' it seems to be nerves rather than motiong sickness---I put baby bibs on him for the slober-----I do take his food away the night before we leave---when we get to the campground all our friends come to visit him
