"The Porta-Pawty+" Covered Travel Litter Box - Portable Bathroom for Cats

I bought this litter box because I am traveling across the country with my two cats. So far it seems to be working great! It's foldable so I can place it under the seat when it's not in use and it's private enough that my cats feel safe using it. One of my cats is rather large so it is a little small for him, but he still uses it without any issues.
