Catuals Rosemary is a 100% organic and 100% vegan product to remove foul odors from the litter box. The odor eliminator is a sustainable product and the packaging meets the highest EU standards. With the Catuals Rosemary, you don't have to scoop the droppings out of the litter box every day, because it leaves your litter box smelling fresh for a long time and it has a high absorption capacity. Catuals Rosemary can be used with any kind of cat litter. Per usage you use a smaller dose and therefore it lasts longer than other scent removers.
