Littermaid Self Cleaning Cat Box

How it works. After cat leaves the unit, sensors are triggered, setting the timer for the cleaning cycle. After 10 minutes, cleaning cycle starts and rake moves clumps toward waste receptacle. Rake opens waste receptacle cover and deposits clumps before closing cover and returning to home position. Sealed disposable waste receptacle with carbon filter allows for safe, easy disposal of waste.
