Questions & Answers

17 Customer Questions

can you use arm and hammer carpet fresh in the cats litter box?

Answer by Chewy • Sep 29, 2020
This powder is designed for use within a litter box. In a clean, empty litter box pour Arm & Hammer Litter Deodorizer to cover the bottom of the litter box. Add any type of cat litter as usual. Sprinkle deodorizer on top of litter and mix in. After the cat does their business in the litter box, they will dig to cover up their urine or feces and mix in the powder themselves.

What is the specific ingredient(s) used for the fragrance? Several people have posed this question, but you have not answered it. Is it natural, is there perfume? I'm trying to avoid chemicals and synthetic ingredients.

Does this hav3 a strong scent?

Answer by Chewy • Feb 07, 2018
This product has a mild scent.

Hi. How is this different from the double duty arm and hammer deodorizer? Thanks.

Answer by Chewy • Jul 07, 2020
This product is not as powerful at combatting odors as the Arm & Hammer Baking Soda Double Duty Cat Litter Deodorizer. Both deodorizers are moisture activated to refresh your cat's litter. The Arm & Hammer Litter Cat Litter Deodorizer Powder is also ideal for multiple cat households.

Won't buy again

I accidentally bought this instead of the 30 ounce box. This 20 oz box is actually more expensive than the 30 oz with no difference in odor control. It's my fault

100% improvement in litter box odor

What a relief. My sweet new kitty created a terrible odor in the litter box, so much, so I dreaded cleaning it out. This Arm and Hammer litter deodorizer worked miracles. Just the fresh smell of the deodorizer itself. Fortunately, Mika doesn't mind it at all.

Nice product - getting harder to find

Prices keep jumping on this but I find a little sprinkle in their litter cuts down on odor. Doesn’t bother them and keeps it smelling fresh.

We’ve been looking for a good de-stinky solution forever, and I hate the way scented litter smells. This has a sort of “fresh linen” scent, and honestly works so much better than just baking soda. It lasts up until the whole box needs to be changed, and no awful chemical scented litter smell.

Cat litter Deoderizer

I recently ran out of the Arm & Hammer Litter Cat Litter Deodorizer Powder. I could tell immediately. His litter box is in the basement. Without the Deodorizer

I recently ran out of the Arm & Hammer Litter Cat Litter Deodorizer Powder. I could tell immediately. His litter box is in the basement. Without the Deodorizer Powder, I could smell his litterbox all the way upstairs! The Arm & Hammer Litter Cat Litter Deodorizer Powder has a fresh, clean scent and generally covers up or eliminates the nasty ammonia smell. I will definitely be using using this again!

A friend of mine uses this in her cats litter and you can’t even tell there’s a box lying around. I figured I give it a try because the price was excellent. I’ve used it a few times already and there has been a massive difference in the now non-existent litter smell. I’m super happy with this product!

Works great! Can't tell I have 3 cats. Amazes guests who don't know I have cats but catches a glimpse and comments on it doesn't smell like a house of cats.
