We have a pretty good size house for our cat to run and play in. When we go camping it takes a day for her to get used to the RV again. We always take her toys and treats from home and as long as we feed her, she is perfectly happy. She too is a timid cat. Take your cat along and be patient. Don't open the door too quickly or too wide until you know where she is. Especially when coming back to the RV after being away. You will enjoy it and so will she. We often spend a few hours, not overnight, in the RV for a few days before leaving. Chuck
