Composts brilliantly, no smell, best litter ever.
Over the past 17 years, with around 6 cats usually, I have tried lots of different litters, including World's Best, and all the rest. I prefer this one. I scoop poos, shake in the scoop to remove excess litter, and flush down the loo. Clumps of wet litter are scooped into a lidded bucket once a day and put on the compost heap, where the nitrogen is a great compost accelerator . This composts really quickly because it retains moisture. The wet areas turn into a soft clump like a ball of dough that is easily scooped out. Works best if you have a good depth of litter; if it's too shallow then the wet clumps go sticky. I've not had a problem with tracking; much better than wood pellets from that point of view. I do use it in deep litter trays mainly , ie plastic storage boxes, and when the cats climb out the litter falls back in. This is a tip I read ages ago , and certainly my cats prefer the deep boxes to normal cat litter trays.
