Litter boxes now split into crystal trays, clumping robots, and roll-to-sift boxes with no motor. We kept PetSafe ScoopFree models, Whisker Litter-Robot 4, PETKIT PuraMax, Casa Leo’s Loo Too, and Omega Paw’s Roll ’N Clean.
We only used Amazon US listings whose product title we confirmed. Mix is budget, mid, and premium. Check size charts on the card — a medium harness is not a large crate.
