Clumps well, but NO odor control
I, unfortunately, bought two massive bags of this without trying it, and have found after just 4 days the stench unbearable. Basil is a very tidy cat and covers his poop well, but the stench permeates the entire flat and is absolutely grim. I keep the window open AND have an air-purifying machine running constantly, and this litter does nothing to help.
