Modkat Flip Litter Box vs IRIS USA Top Entry Cat Litter Pan

Buy the Modkat Flip if you want a covered box with a flip lid, a reusable liner and charcoal filters that keep odor and high-pee spray in. Buy the IRIS top-entry pan if you want a simple, deep open-top box that stops dogs and litter tracking. The Flip has the stronger reputation: 4.8 from about 3,970 ratings against 4.5 from 368, and a Wirecutter upgrade pick. Owners say the Flip's liner and magnetic lid make scooping and dumping easy; the IRIS is cheaper in build and simpler, with no filters or liner to replace.

• Choose the Modkat Flip if your cat sprays high or you want odor control, a reusable liner and a lid that flips open for scooping.
• Choose the IRIS top-entry pan if you want a deep, simple box that keeps dogs out and traps litter on the grooved lid.
