Review on HAMMER® Litter Deodorizer Powder Pack by Amy Fenner

I have been using this product for several years. It handles litter odors well on multiple cats (started with 3, now up to 1) and is a nice complement to the clumping litter I use (Fresh Step). In several cats, this appeared to reduce territorial behavior compared to using two litter boxes. It deadened odors, and as long as we kept the trays scooped up in combination with the powder, they could share. It's a powder but doesn't seem to add any dust from the filler. If anything, it's holding him back a little. I will continue to use it as long as we have a cat.
