He doesn't really like this tiny crate - see how sad he looks? But it works well for car travel because it has a place on top to run a seat belt through. That way if I have to suddenly stop, the crate won't fly off the seat. He tolerates it pretty well, and if I'm really lucky he'll go to sleep. If I'm not really lucky he'll start howling along to the radio. (Gotta have some music on the road!)
I always take along his food, water, and some treats. Yum! His favorite part of every trip!
