How many out there have cats that travel in their RVs?

We take our cat on almost all our trips, short or long. She travels great and is largely self-sufficient. We put the litter box in the pass thru and then made a cat door in the end of the bed. As long as the cat has food and water, and the trailer is kept in the shade (or at least cool) it is no problem. We also walk ours on a leash.
