Thanks for the advice , we are still in the early stages of traveling with cat. I can visualize all the cubby holes and unreachable hiding spots. It would change our vacations, and frankly, for a scardy cat like mine, she almost seems better off alone in our house, as everything frightens her, even a closed door. I have also looked at long crates, soft and not. She has rubbed her nose raw in the soft crates even at the vets, and as much as I like them better, no way could I leave her alone in it.
My problem is I'm not home much during the day because I photograph wildlife and sometimes don't get back to the RV until 8 at night. There seems to be as many worries taking her with us as leaving her home. But I miss her and feel guilty! My neighbor feeds her. I guess we will start out slow, but even a dog walking by is a trauma!
