Never knew I needed a litter box enclosure until I purchased this on a whim. Perfect size for my bathroom and roomy enough to hold the large stainless steel litter box my cats use. I like how it can be built with the opening on either side so you can build to suit your needs. Inside height was slightly larger than most boxes of the same size which was a huge part of my decision to buy. Best of all my cats took to it immediately and it traps most of the litter from coming out of the box. Great easy access doors for daily little box maintenance.
