Max's Cat Litter is a premium quality product that has been developed to cater for the personal hygiene needs of cats and other pets. The secret to Max's Cat Litter is Oryzalite, an exclusive blend of plant materials from Australian rice farms, which is formed into free-flowing granules. This results in a natural litter material that is effective, easy to use, easy to dispose of and friendly on our environment. Effective Odour Removal. Cats and other pets do not like a smelly litter tray and neither do we. The smell of ammonia (a key component of foul odours) was kept to almost undetectable levels in experiments conducted by the Centre for ChemoSensory Research. Natural & Garden Friendly. Max's Cat Litter is made from natural ingredients, does not contain any harmful chemicals and is completely biodegradable. It also contains useful nutrients and trace elements, making it an ideal garden compost with the ability to improve soil structure.
