Closed Sandbox Smart Self Cleaning Cat Litter

The Closed Sandbox Smart Self-Cleaning Cat Litter is Noble Paws's take on the automatic litter box. It is a hooded, enclosed unit in white ABS plastic with a self-cleaning mechanism that handles the clumping and sifting, so you scoop far less often. Waste drops into a separate compartment you empty when it fills, and built-in filters work to keep odor down inside the closed housing.

The enclosed shape gives the cat some privacy and keeps litter from scattering across the floor. Detachable parts make it easier to clean out and refill, and because the cleaning cycle is efficient, it tends to use less litter than an open tray. The unit ships as the Pro version that pairs with a companion app for added control.

A few things to know before you buy. The product page lists white as the only color and does not state the power source, litter capacity, or cat size limits. It also describes the design as both fully enclosed and semi-closed in different spots, so treat it as a hooded, mostly enclosed box. The app's exact features are not detailed on the page either.
