Works With All Litter Types

Arm and Hammer Cat Litter Deodorizers can be used in all types of litter. So, you do not have to worry about whether or not your particular litter type or texture is compatible with the brand.

Maintains Freshness

Baking soda is a powerful odor neutralizer because it can absorb odors rather than mask them. Most unpleasant scents are acidic, and baking soda's alkaline nature neutralizes the pH, allowing the litter box to maintain freshness.

Moisture Activated Scent

This cat litter deodorizing powder contains a moisture-activated scent, which will kick in and release a fresh scent each time your cat uses the litter box.

Easy to Use

The Arm and Hammer Cat Litter Deodorizer is easy to use. For the powdered versions, all you have to do is cover the bottom of your clean litter box with the powder, fill it up with the necessary amount of cat litter, then sprinkle more powder on top and mix it in.

As for the Arm and Hammer Cat Litter Deodorizer Spray, you spray it directly onto the litter after scooping. For the Arm and Hammer Deodorizing crystals, you fill up a capful and sprinkle them right onto the litter.

Most users give positive reviews and have plenty of great things to say about the  Arm and Hammer Cat Litter Deodorizers in powder form. They like that they are affordable and help freshen up better than regular baking soda.

Some customers even sprinkled powder in the trash cans to keep the litter smelling better until it was time to take out the trash. The negative reviews associated with the powdered versions of the products were that the smell was much too overpowering to the point it was unpleasant. Some reviewers felt baking soda alone was just as effective and much safer.

As for the spray version, many users liked that it immediately freshened up the scent of the litter box but complained it didn’t last as long as the powders. Like with the powders, some felt the strong perfume scent was too much to handle.

The Arm and Hammer Cat Litter Deodorizing Crystals were the least popular among reviewers. In addition to feeling it was overpriced, they felt the scent was mild and didn’t make as much of a difference as they desired. Some preferred it over the powdered versions, however.
