Frequently asked questions

Are self-cleaning litter boxes safe for cats?
Reputable models use weight and motion sensors that pause cleaning when a cat enters. Nervous cats may need time to adjust, and very small kittens can fall below detection thresholds.
What litter do self-cleaning boxes need?
Most require clumping litter so the mechanism can separate waste effectively. Check the manual, as some units specify particular litter types and may not work with crystal or non-clumping litter.
Do they remove the need to clean manually?
They greatly reduce scooping, but you still empty the waste drawer regularly and periodically wash the unit. Multiple cats fill the drawer faster and may need more frequent attention.
