Terracat cat litter is made exclusively from 100% Greek betonite, a natural product of volcanic origin. Betonite is considered as one of the best raw materials for cat litter as it has high absorbency (swells to approximately 15 times its original volume) and causes directly the creation of solid clumps when wet. The rest of the sand is kept dry and clean, without odours and 99.9% free of dust. Its cleaning is easy and TerraCat cat Litter remains fresh for longer, offering peace of mind and economy.
