My cat doesnt travel well. In fact he's the least happy cat in a car ive ever known. Invariably, when we go to the vet, he craps in the cat carrier. The last time I went I brought two of them with me, and transfered him from one to the other once we arrived there because again he made a mess. The vet I go to is a 20 minute drive away. Next time I take him in for a checkup or whatever, would it be a good idea to not let him have food for maybe 24 hours before and watch the litterbox to make sure that he's "empty" before we go? I havent figured out a way to make the drive less stressful, and I dread the fact that about halfway there my Jeep fills with that horrible ammonia smell. What else could I do, suggestions please?
