Crystal Clear Litter Scoop Large holes - designed to allow the LITTER PEARLS to fall through, with a minimum of shaking, when extracting the faeces from the cat litter. Extra strong - enabling it to easily cope with the stirring/raking of the LITTER PEARLS in the cat litter tray for maximum product life. Works brilliantly with ALL TYPES OF CAT LITTER - ensuring that only clumps (or lumps) are taken out.
