Travelling with a cat?

Opie, your description sounds like our Nellie. She will not go potty outside. If she's outside on her leash, she meows at the door to be let in, goes potty, then sits at the door and meows to go out again. She loves being out in the evening when it's getting dark (right now we're in a city campground with no wild animals about) and she'll sit out there for hours. She also insists on coming with me in the a.m. when I take our dog for a walk. I usually just lock her leash to the longest length then she just drags it along. If we're going somewhere new, I'll pick it up and she walks just like a dog...except she has to stop every 3rd or 4th step to look around. She likes to keep our camper in view though so sometimes we leave skid marks in the sandy gravel here where I have to encourage her to continue with the dog and me.

She travels in the pickup when we're on the road, along with the parrot and the dog, and they stay in there until we're set up. She always has her harness and leash on when we're traveling.
