Natural silicone cat litter is perfect for demanding owners of cats. Silicone gel crystals are extremely absorbent. They contain millions of tiny microscopic pores that absorb liquid and undesirable odors. Thanks to the special structure of silicone, crystals will not stick to the cat's paws so they can stay clean and dry. Scents and impurities remain trapped inside the crystals so there are no more urine-soaked clumps! Silicone sand is 100% natural, biodegradable, non-toxic and environmentally friendly. One bag of 3,8 L will last a month.
