After there has been silica gel coarse litter, no smell because everything is absorbed by the silica, but no real way to separate the virgin silica impregnated.
Now there litter into very fine silica grains: it does not smell, and it's great clumps, suddenly we can eliminate the balls as you !!!
My tip: mix the litter with the fine silica coarse, it gives more volume (no need to put two bags of fine suddenly litter) and it agglomerates as well.
There are two drawbacks: the grains are so thin that my pussy was released in more outside the box (that's a bit much), and it is anyway a bit expensive (that's why I mixtures).
