I add "Fresh & Clean" Cat Litter Deodorizer (Arm & Hammer) to the cat litter each time I add new litter to the cat boxes. It works really well to extend the life of the cat litter we buy (Fresh Step).

It seems like its just scented baking soda and I'm wondering if I added that if it would do the same thing?

Anyone else add anything to their litter boxes? If so, what?
