This super clumping bag of cat litter is made from natural clay with activated carbon. Bentonite clay is finely grained and quick to form clumps when wet, with an ability to absorb liquids up to three times its own weight. The clumps are easy to remove when cleaning, leaving a fresh and clean tray with less product wasted. The addition of active carbon helps improve the overall porosity and odour, as the inner surface of the carbon contains microscopic pores which act as a natural filter. This low dust formula makes it safer and more comfortable for cats and humans alike.
