I have to travel for Christmas and will be away for seven or eight days. It's a 4-5 hour drive taking into account stops. I don't have a setup that would allow for a week of food or water for my rats, and I don't think I will be able to find anyone to come over and feed/water them. I plan to put their 106 qt tub in the back seat. Will the ride stress them out? Anything I could do to lessen the stress? Thanks.
