Scoop Free Self Cleaning Litter Box Replacement Cartridge
This is just easy to use for indoor cats and there is no mess to clean up at all
I've tried various litter trays but this one is fantastic. No mess; no fuss and litter remains in the tray not all over the the floor. Plus my burmese loves the privacy!
no need to clean the litter every day and great disposable tray without mess.
