We travel with our cat all the time. He travels in the truck cab because he throws up if he travels in the camper. He gets a very small dose of a tranquilizer each day. He loves being with his people ine the camper and is fine once we stop. He's not very interested in going outside. He's always been an indoor cat (15 years old). You have to be careful about leaving an animal locked up in a camper in warm weather. We leave the Fantastic Fan on when we are out. We've never found the camper too hot after a day out, but we only go to higher locations in Colorado in summer or to places with AC hookup where we can leave the air conditioning on.
