Replacement seals for the top of the base, which help with odour control and litter spill. Easy peel and stick design.
Suggested replacement is yearly, or as necessary, depending on cleaning, litter and number of cats.
Note cleaning by brushing with a stiff bristle brush, and vacuum to remove dry particle and dusty, then wipe with a slightly damped cloth, to extend longevity. For odours, the Litter-Robot cleaner is very good for light application and brush or wipe off. Available under accessories.
