21 Self-Cleaning Cat Litter Boxes, From Semi-Automatic to Touch-Free

ZeaCotio Self-Cleaning Cat Litter Box with Air Vent System ($350, originally $499)

This extra large litter box is elevated on four legs, which support the waste drawer at the belly. It's equipped with 10 safety protection sensors that stop the litter box from moving through a rotation when a cat is nearby. Since it's so large, this litter box can fit cats up to 20 pounds and can store waste for up to 15 days if you're planning a long vacation. Of course, the major bonus is its air vent system that utilizes suction to remove odors. You can even schedule the deodorizing exhaust fan to turn on through the accompanying app.
