Dr. Elsey’s Long Haired Cat Crystal Litter (8 lb) is a hypoallergenic silica gel litter infused with hydrolyzed herbs to attract cats to the litter box. The amorphous silica crystals trap urine and odors on contact, providing superior odor control and keeping the litter box fresh. The soft crystal particle size is ideal for long-haired cats – it won’t cling to their fur or cause staining, keeping your kitty and home clean. Low-tracking and 99% dust-free, this non-toxic litter is gentle on sensitive paws and safe for cats and kittens over 6 weeks old.
