Best litter boxes for multiple cats, ranked by published specs
Published by Adam Fineberg / RobotMatchup · compiled from manufacturer-published data, not hands-on testing
Ranking methodology
Ranked by manufacturer-published data only — waste drawer capacity, maximum cat weight — with models missing those figures ranked last. RobotMatchup has not physically tested these units and no position here reflects hands-on use.
In a multi-cat home the drawer fills several times faster, so published capacity matters most, followed by the rated cat weight range and whether the maker publishes per-cat weight sensing rather than a single total.
