===Open litter pans===
An open litter pan is generally the most basic and least expensive design. They are commonly constructed out of [[plastic]], however some [[disposable]] models exist, in the shape of a rectangular tray with outwardly sloped sides {{convert|10|to|15|cm|in|abbr=off|sp=us|order=flip}} high. Open litter pans allow for maximum ventilation which may increase cat comfort. They show the waste most visibly which cat experts like [[Jackson Galaxy]] point out helps cat carers monitor current health status. 

Litter pans with low walls are not ideal for containing litter when a pet scratches or digs. Some animals may urinate or defecate over the walls. Some designs include a detachable rim to help catch litter when the animal kicks to bury their waste.
