Why can’t I use the Ultra Litter Attractant with paper, corn, pine, perfumed, cedar or other litters containing baking soda or deodorizers?

The Ultra Litter Attractant works on a smell premise and to insure its effectiveness, we recommend using it with only unscented, clumping clay litter. Any other scents in natural litters or perfumes can mask the scent and it may not work properly.
