Perfect for multi cat household
I’ve used Smart Pack for years and wouldn’t change it. The liner fits my XL litter tray, making weekly changes quick and mess-free. I have two cats sharing one tray, replacing the pack weekly, can wipe pee of liner and top it up with a 10L Catsan refill in between change. 3x Smart Packs plus one refill lasts around six weeks for about £30. The larger granules are easy to sweep or vacuum up, unlike fine sand litters that get tracked everywhere. Odour control ++ excellent for multi cat households.
