Quick fit check
Who it fits—and what to check.
- Kittens below the safe automatic-operation threshold require supervised semi-automatic use
- The Amazon option is a bundle; check its included accessories before buying
Check the household fit
Cat fit, litter fit, and maintenance come before app features.
Automatic cycling reduces scooping but does not remove the need to empty the drawer, clean the globe, maintain sensors, and introduce cats gradually.
Confirm cat fit
Review current minimum-weight and physical-fit guidance for every cat that will use the device.
Choose compatible litter
Use a clumping litter type that can pass through the sifting screen and form removable clumps.
Plan the cleaning routine
Allow room for the device and for access to the globe, waste drawer, filters, and sensors.
