Before taking a road trip with your pet, get your pet used to being in a car by taking him out on short journeys. Plan your route in advance and take sufficient stops every two to three hours. Bring a portable litter box with you and make sure your pet is used to it. Never let your pet alone in a hot car. If you stop to fill up the car or take a break, keep your pet accompanied or take them with you. Also it is very important to check with your vet if your pet is healthy enough to be taken on a long journey.
