I have to take one of my little guys to the vet today for his annual checkup. However, he HATES being in that crate. Even though it's just a ten-minute ride, he loudly meows the whole way, and typically he either pees or poops in the crate, so I can't give him a towel to sit on! I have tried placing a blanket over the crate, but that doesn't seem to work. However, I know that he responds well to catnip; should I try that?
