Long Haired Litter traps urine and odor on contact and has the right particle size that long haired cats prefer. Dr. Elsey’s Long Haired Litter is an amorphous silica gel infused with hydrolyzed herbs to draw cats to the litter box. Long Haired Litter is low tracking and will not adhere to the cat’s long fur or color the coat. Each jug contains a free Litter Box Solutions Booklet to help cat owners solve their litter box problems.
