We placed feline urine on each cat litter and stood at set distances from it to see if we could detect any unpleasant smells.

Clay cat litter - different clay types, usually bentonites (which are highly absorbent), which are dug out of the ground, compressed and dehydrated into granules. We're afraid it's up to you to tempt/bribe your cat into liking the one that best fits your time, needs and budget. It may not be reproduced in any way whatsoever without Ocado Limited's prior consent, nor without due acknowledgement.And, when it comes to freshness, hygiene and cleanliness, our furry friends often set as high standards as we do. We checked for dust clouds while pouring out the cat litter, and scrutinised to see how dusty fur gets when a cat pushes the litter around the tray. Sanicat Clumping White is a high quality clump forming cat litter that is naturally white in appearance. We filled sealed containers with as much cat litter as we could and weighed them to see how much you'd need to use to fill up the same size space.

After digging around the litter tray, we checked to see how much cat litter got caught up in the fur to see how much might get scattered on the floor around the litter tray. Wood pellet cat litter - more sustainable than most types, made up of compressed and dehydrated wood or sawdust, often made up of byproducts from wood production used to make something else, such as furniture.

Our three different litter families allow you to make a choice that is right for your cat and also gives you peace of mind in knowing that your furry friend has a clean, hygienic space that keeps the environment in mind. Plant fibre cat litter - arguably the most sustainable option, made from a wide variety of natural waste products, from corn or wheat fibres to peanut shells. Silica cat litter - silicon dioxide minerals which are often mined from quartz sand and heated until they crystalise into gel granules. Thus, we pride ourselves as the experts in cat litter and know that we have a perfect solution for you and your cat.
