The litter is perfect for multiple cats. I have 2 and I use a little less than one bag per month removing needs of cats regularly. Liquid form a compact mass in the bottom of the litter box it is easy to remove in seconds. The "Save a Subscription" is very convenient because I get my bags once a month without having to remember to control litter and rates are advantageous regularly (between 8 and 12 euros against about 16 commercially available)
