Questions & Answers

17 Customer Questions

Do I have to put a thick film of the powder ontop or sprinkle it to just coat? Also, am I supposed to mix this in or leave it ontop?
Answer by ChewyAug 02, 2021
In a clean, empty litter box, pour deodorizer to cover the bottom of the litter box. Add any type of litter as usual. Sprinkle on top of litter and mix in. Between litter changes, sprinkle on top after scooping to keep litter fresh.

What makes this particular product "double duty" versus the regular Arm & Hammer litter deodorizer powder?
Answer by ChewySep 17, 2020
They both contain moisture activated SBC crystals and odor neutralizers. The ARM & HAMMER Double Duty Cat Litter Deodorizer Powder also contains additional odor neutralizers specifically developed for fecal malodors.

Unusable - the smell!

I was excited for this deodorizer believing it was baking soda based to eradicate smells. I did not realize it was heavily perfumed, so strong I couldn't even bring the box into the house, it is sitting outside, it smells THAT bad. I will keep looking for something that is not strongly perfumed with awful scent I'm allergic to, or maybe just get a box of baking soda.

Yikes no more

Very impressed with how this acts as a pleasant deodorizer opposed to the yikes, who stepped in animal feces? Just line bottom with the double duty deodorized litter until bottom is covered. Add litter. Sprinkle top again with double duty & mix into litter. Excellent & enjoy company without smelling animal feces. Highly recommended

Eye watering scent

Cats do not like strong smells. When I sprinkled it on the litter, the scent was overpowering. I can only sprinkle small amounts at a time. The smell is too overpowering. I may go back to using their baking soda , which works just as well, without all that unwanted fragrance.

Awesome deodorizer

This deodorizer works great. Although, we only have one cat in the house, we do have two litter boxes; one in the half bath downstairs, and the other in the master bathroom upstairs. Our cat Socrates is very picky and he definitely likes a clean fresh litter box. Just sprinkling a little each time you scoop out the box keeps the bathroom smelling fresh, and our cat happy!

Wished I bought this sooner

Having 2 cats, the litter can be a little overwhelming even with scooping. This works like a charm, will be reordering!

It works really well

I used this years ago and loved how effective it was. So when I saw it recently I knew I really needed it with 4 grown cats in the house adn odor can take over very quickly. I use it when I change the cat litter, just a light sprinkle and then later in the day I give another sprinkle to help contain the odor. I use only one litter box (don't judge), I tried using more boxes but my cats insisted on using only the one (I guess the family that poops together stays together, not sure) so it can get smelly quickly, its a big litter box so it is changed daily and no it doesn't over flow. This deodorizer really does keep my house smelling good. I don't think its to strong, My cats don't either, my little Shuga usually jumps in the box as soon as I'm done to claim it again and she has never had a problem. So thank you for this GREAT product, it keeps my house un-smelly and my fur babies like it too.

Arm & Hammer Litter Deodorizer

This product really does help the ammonia odor in my litter box. I have to cats and I only sift the liter box 1-2 times a week

Excellent Packaging

I have bought this product many times from another large retail store. I have never been as pleased with the way it has been shipped to me as I was when I ordered if from here. Each box was individually wrapped with plastic so that it would not open and spill everywhere, and it was neatly stacked in the box. I was very pleased and I was very pleased with the price. The other box store charged double to ship and would only allow 5 to be bought. I will order from chewy from now on.

I received a scented one

The baking soda works but I checked the image online and the heading and the description The product I got was linen scented and very strong exactly like laundry detergent. I was not sure if this was a mistake but if you do not want anything scented this will be a pass.

Regular arm and hammer works just as well

It has a powerful fragrance when you first sprinkle it that takes about 30 minutes to fade, and it seems to work ok for a day or so, but I have used regular baking soda in the past with the same result minus the strong fragrance. All in all, I can understand someone wanting this, which is why I gave 4 stars and would recommend, but for me the fragrance is too strong and it doesn't last long enough on a big litter box with 2 cats using it. I did follow directions, and I can't tell where adding it when putting fresh new litter to start made any different than just having fresh litter. But after a week, adding it only reduces odors for like a day.
