    This product is wonderful! All you have to do is sprinkle a little bit in your cats litter box and no more odor. It’s great give it a shot. I think you’ll really like it.

  8. Emma

    This stuff is fantastic for odor control and the scent doesn’t bother my cat’s allergies. Clean the litter each day and sprinkle this in weekly. Nobody will know you have cats.

  9. Bri

    A small sprinkle of Arm %26 Hammer litter deodorizer helps keep the kitty litter from smelling unpleasant. The cats don’t seem to object to it as far as I can tell. I’m wondering why so much of the product leaks out of the boxes when they are on the shelf or being shipped. It gets all over my shelves and seems very wasteful.

    The only one brand I can trust when it comes to deal with pet odors, mostly cat’s. Works like a charm. It doesn’t require to be used very often. Great quality!

  11. Carolyn

    I have been using this brand for decades. It is the only one that I use. I have had lots of company over and they walk by the cat box and take a step back and ask what is that wonderful smell. You only sprinkle very lightly and Use the scoop to spreed it through the litter.

  12. Justina

    You’re missing out!
    Definitely needed this a long time ago! Makes such a huge difference after a litter box cleaning and i only sprinkle a bit across the box. Too much WILL choke ya. It smells so good though.
