Amazon have made it so easy to keep up the supply of cat litter at home by their subscription scheme. You don’t have to search around and transport, it’s delivered every month to your door. This size (30L) is perfect to store and a lot cheaper to buy compared to getting the smaller sizes from the supermarkets. The quality of this litter is top notch and it is environmentally friendly as it’s made from recycled paper. My cat is quiet fussy and we have never had any problem with her using this litter.
