Well, he will be traveling with us as the weather gets better. It's not just a van it's a VW camper van and we have traveled with our kitties since one of them became a diabetic in mid 90's. We lost him and the next one too last summer, so now our new fella, now named Sugar Ray will be spending lots of time in the van. I'm not sure if the Feliway will be a necessity, tho as he has settled in to use the box quite well. We feel the seat was a startle response and lack of previous litter box use/acquaintence.
