1. IRIS USA Premium Top Entry Litter Box
IRIS USA
The IRIS USA Premium Top Entry Litter Box's compact footprint and litter-trapping lid keep mess contained in tight living spaces. The highlights are top-entry mode has one of the smallest true footprints of any large-capacity box and the lid design traps litter on exit, meaningfully reducing tracking across small apartment floors. The tradeoff: no automatic waste removal, still needs daily scooping.
