The litter is made up of a single component, silica sand which, thanks to the natural micro-capillarity of the granules, instantly absorbs the liquids it comes into contact with, retaining urine and bad odors and thus preventing the proliferation of bacteria in the surrounding environments. Silica sand granules absorb more than three times their own weight of liquid. Affordable and durable, one package is enough for one month of use for a cat of average weight. The packaging is practical and light to carry. Available in two sizes: 5 lt and 16 lt.
