Ah, sedation. Our vet wouldn't give us Acepromazine because he said it might give our cat a "paradoxical reaction" if he's too hyper. He said to use benadryl instead. Funny thing- my cat had a paradoxical reaction to the benadryl, and was practically crawling out of his skin the whole first half of the trip (an overnight flight, people were not happy) until it wore off, and then he was almost normal the whole rest of the way with no drugs. I suggest trying out whatever drugs the vet gives you (which I did do, but thought maybe the dose was too low) ahead of time, and make absolutely sure your animal is sedated by taking them for a car ride or some other stressful activity. You do NOT want this to happen to you!
