I've lucked out with cats who travelled well. One of them was a great camper, and when I drove cross country I had a pickup with a sliding glass window in the back of the cab and another one in the front of the camper shell. Her litter box was at the back of the bed of the truck, and she would indicate she wanted through and I'd open both windows. There wasn't much space between the windows so no danger of slipping anywhere, but it was a bit of a wind tunnel if we were driving.

It looks like we'll have nice weather this weekend so I won't try to predict what I might accomplish indoors. I'm gradually working my way down a list, and in a couple of weeks I'll be adding some more after I have a guy look at the house and tell me what kind of shape the foundation is in. I have a couple of projects that require the advice from someone who knows about foundations, and depending on their cost, they may move up near the top of the list.
