Catsan Hygiene Cat Litter has been developed specifically to match your cat's natural needs, using one key feature – hygienic white quality grains. Made of individual grains of fine chalk and natural quartz sand, Catsan Hygiene absorbs liquid just like a sponge, keeping your cat tray nice and dry. These grains also stop bacteria formation in its tracks and absorb odours before they can really take a hold. This long-lasting odour protection makes Catsan Hygiene a real favourite among cats. The natural chalk and quartz grains used in Catsan Hygiene provide this litter’s hygienically-clean colour, reassuring you that your cat is not being exposed to dangerous fibres or other unsuitable substances. Catsan Hygiene provides both hygiene and extra mineral protection for ultra reliable and long-lasting odour prevention – the only cat litter to do so! Catsan Hygiene Cat Litter – absorbs before the odour takes hold. A cat litter that truly has your cat's well-being at heart! It's this simple: Fill your cat tray with at least 5 cm of Catsan Hygiene. Remove stools daily and occasionally shake the cat tray to mix up the litter. Completely change the cat litter at regular intervals. Tip: If you have underfloor heating, place an insulating mat (wood or styrofoam) under your cat tray. This prevents odour produced by the heating up of liquids locked in the grains.
