Smells like dirty rabbit hutch
I was seeking a 'green' cat litter that clumps. This clumps adequately, but there is no odour suppression (although it is perfumed). My cats have a tray each, and the dirty litter is removed daily. Once this litter is damp from urine, it smells like the wood shavings used in rabbit cages - after they haven't been cleaned for a week. The smell was so bad I just gave up and emptied both trays completely after a few days. Might work for cats that have a 'poo-only' tray - or small rodents.
