Nullodor Silica Litter features micro-porous granules that absorb liquids quickly and effectively, ensuring that your cat can always enjoy a pleasant, dry litter tray. These litter crystals are 100% natural and only need replacing every 4 weeks. They are also compostable and help to neutralise nasty odours in your cat's litter tray. Nullodor Silica Cat Litter granules with efficient micro-capillaries have an absorption rate of 150%, absorbing liquids in a fraction of a second. The moisture then evaporates slowly to leave your cat's litter dry and suitable for re-use. Nullodor cat litter also completely traps unpleasant odours in the core of the silica grains for a month. Ammonia emissions are blocked by the micro-porous crystals, leaving everything clean and fresh. Although the cat litter will gradually begin to turn yellow, this does not reduce its effectiveness. Stools should be removed on a daily basis and the litter should be shaken around in the tray every day to avoid saturation of the same area. This 100% natural silica cat litter is dust-free and anti-static, meaning that it will not stick to your cat's paws. A 1.5kg bag of Nullodor Silica Cat Litter is very economical and only requires minimal storage space.
