Cat’s Best is a 100% natural cat litter, free from chemical additives and completely biodegradable. Thanks to the active wood fibers, for which no trees are cut down, the litter is very efficient as it can absorb and permanently encapsulate up to seven times its volume in moisture. Cat’s Best litter is clumping, highly absorbent, and compostable. Cat’s Best cat litter sustainably supports the hygiene and health of your cat.
