I got it online at Pet Playpens. I originally saw an ad for them in one of our motorhome magazines.

Although....it's really simple. It's just 3/4" PVC pipe with some sort of netting around it and on top of it. They gave us rope to attach the sides, but as you can see we've already started modifying by using releasable wire ties. The releasable wire ties are kinda hard to find, but we found some at Home Depot.

I also got the "fake grass" stuff to put on the bottom because if we're camping, you never know what the ground is going to be like or what sorts of chemicals they might put on it, so that was just an extra protection thing that I preferred.

catlover4ever, in a couple years we're going to go full-time in the motorhome, so leaving the kitties at home is not an option. That's why I wanted to find something like this. It's perfect because it's easy up/easy down and when it's down it fits in a relatively small area. Storage space will be at a premium when we're full-time, so I needed something that breaks down into a nice compact package. So far, I think I've found the ideal solution!
