Litter Magnet, 20 oz (1015081)
Litter Magnet, 20 oz is an all-natural way to encourage problem cats to uses the litter box. Litter Magnet takes advantage of a cat's sense of smell by providing a tilled earth scent, a favorite area for cats to use the "bathroom."
Smells like dirt
Sprinkling a little of this into cat litter is supposed to make cats use the litter box. It worked as described for one of my cats, but it caused the other to sneeze and avoid the litter box like the plague. I'll assume she's allergic to it and it is not a problem with the product. Your mileage may vary.
