We have a 17 year old cat. Katie adapted well to the RV. She stays under the driver's seat while we travel. She is attached to my hip all the time, so under the seat she feels safe. Her water is under the passenger seat while the food bowl is near the bed in the back of our Axis 25.2. she loves the dash to hang out while camping. I removed the small cabinet door under the bathroom sink. I also removed the shelve. The small litter box fits perfectly under the sink and is easily cleaned from there. No way it's going in the shower!
