Automatic litter boxes use special motion sensors that detect your cat's presence and begin a cleaning cycle after your cat has finished taking care of its business. Some self-cleaning litter boxes make use of a rake to sift the litter and separate the clumps. The waste clumps are deposited into a waste receptacle. Some litter boxes utilize a conveyor belt to transfer the clumps to a litter bag. They are powered by electric motors that can be activated by plugging into an electric socket. They automatically activate the cleaning process once your cat leaves the box. The receptacle where the waste gets accumulated is equipped with an odor-control system that traps any foul smell. If your pet is shy, it may get startled by the mechanics of the litter box initially. It is recommended to scoop the clumps manually for the first few days. Let your cat get comfortable with the new system. Once your pet gets familiarized with the new litter box and starts using it regularly, you can operate it automatically.
