The high-performance litter uses the starch in the vegetable fibres for super-fast clumping, leaving the surrounding litter and tray perfectly clean. The plant enzymes swiftly neutralise odours offering safe and natural protection from any nasty smells. It owes its efficiency to the extremely fast lump formation which means that only the top layer of the grit needs to be replaced. This keeps both the litter box and the remaining grit clean. The urine is immediately absorbed and unpleasant odors are immediately neutralized. Its also very affordable. If you follow the instructions and use a basic layer of 2 cm, you will need approximately 500g of cat litter per week (average consumption of a 4 kg cat). * Check the local regulations. Never flush all the cat litter down the toilet, only the lumps.
