The best cat litter system
We can make a single pack last a week if we scoop out the poop every evening & add an extra scoop of fresh litter to the tray halfway through the week. We line the tray with a plastic liner to make it easier to clean. We also have a large rubber mat with short "bristles" under the tray to catch any spare litter, & prevent it from being trod into the carpet. Catsan, as far as I know, is the best litter for preventing odours, ease of use & value for money.
