Richell Expandable Small Pet Playpen with Removable Floor Tray - Portable Indoor/Outdoor Dog & Puppy Play Area for Home, Yard, or Travel

We wanted something that could go under a litter box to pick up any excess, spills, or complete miss calculations by an aging, blind cat. This has worked wonders for the purpose. I love the expandability of the product, which helps greatly in tight places. There has been absolutely no leaks and the material is soft, yet grippy enough for an animal to walk on and to pick up debris. The material is very sturdy and has lasted months without wear or tear. When wiped down it looks brand new, even after daily use by two cats.
