Non-toxic and 100% natural. Purrfit clay litter, with specific shape and size pieces, is designed to reduce dust and prevent litter being tracked around the house. It is also soft on your cat's paws, encouraging them to use the litter regularly. Excellent odour control, as this litter naturally absorbs the ammonia that is in cat urine, locking away strong odours and leaving your home clean and fresh. Non-toxic so ideal for kittens.
