What are your best tips for transporting pets? I spray Feliway in cat crates if we have it around beforehand, and I've found that ambient electronic music tends to calm them. One of my favorite CDs to play on transports is by Cantoma. I haven't had a ride where I've played it that a crying or stressing out pet hasn't settled within about 5-10 minutes of turning it on. I just have to make sure I don't play it for too long on longer rides, because it'll calm me right to sleep.
I feel like everyone probably has 1 or 2 of these kinds of tricks-- it'd be great to have a few more!
