Overview
An automatic self-cleaning litter box with safety sensors, an S-shaped sifting screen and a removable washable liner, sized at 15.8 gallons and built for cats between 3.3 and 22 pounds. It ships with a power adapter, liners, deodorizer and air purifying liquid.
Self-cleaning boxes automate the sifting step owners otherwise do by hand, using a screen mechanism and safety sensors meant to stop the cycle if a cat is inside. The included consumables, liners, deodorizer and purifying liquid, cover the first round of use before restocking is needed.
