How old is your cat? With my kitten Sasha, I knew that i was going to have to take her on a lot of car rides because i am in college, and i need to take her with me on christmas and spring breaks. My vet ( who i highly trust) just recommended to me that i just never put her in a carrier to begin with. Now, Sasha LOVES car rides, and purrs for most of the 4 hour drive home. She just sits on my lap, and is perfectly calm and content. I dont know if this will work for you, and i would reccomend testing it on a very short drive before going on a long drive, good luck :wink:
