PrettyLitter Clumping Cat Litter, 10 lb, eliminates odours and changes colour to help you keep tabs on your cat’s health with its revolutionary pH indicator. With ultra-absorbent, low-dust, clumping crystals, this litter is ideal for single and multi-cat households. The easy-to-clean clumps trap odours two ways: the silica gel crystals absorb moisture and odor on contact, then the clumping agent allows users to simply remove the waste from the litter box entirely. Say goodbye to litter box odours for good and hello to the peace of mind that comes with health-monitoring cat litter.
