We love Cat Spot litter. The cats use it well. Its so easy to dispose of (in summer we put it in the garden, in snowy winter we often put in the trash). We love that it all natural. Its great to dispose of poop in the toilet rather than have to throw away. Love the non clumping. Love it is delivered to our door. A box of litter lasts our cats lasts 7-10 days before we change it out for clean. We add baking soda about 4 days in to help with odor -- it will smell an little of ammonia at that time even with daily stirring -- this helps us extend it to 7-10 days. 1 bag will work to fill and refill 2 litter boxes twice in general. We've used a different brand of coconut coir litter and it was not nearly as good. We will stick with Cat Spot.
