Review on Cat's Pride Disposable Litter Pan - All-In-One Pan and Litter Solution for Cats by Jon Odom

Perfect for travel or to keep a pair in the trunk in case a bug is found. I only needed two or three for a quick emergency evacuation, but they also work great in a garage if you have an old clunker that is dripping oil. Garbage is no more than a centimeter, but if necessary, it will do. I think you could bring an extra small bag of litter just to please the cats, but they will use it if that's all they have. Fits perfectly in a 27 gallon bag filled with essentials. Be prepared and take it with you just in case.
