Another reason for not leaving the cat in the trailer: our trailer can get pretty hot during the day in summer. I'm much more comfortable keeping Snowball in the truck with us with the A/C. We got a remote start installed that will allow us to keep the truck running up to 20 minutes with the doors locked for those inevitable bathroom breaks.
