Questions & Answers

19 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 Chewy • Aug 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 Chewy • Sep 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.

What's the difference between this to just plain baking soda?

Answer by Chewy • Nov 12, 2021
While both products can be used to deodorize cat litter, ARM & HAMMER™ Double Duty Cat Litter Deodorizer contains moisture activated odor absorbent crystals and odor neutralizing ingredients.

Is this product scented or unscented?

Answer by Chewy • Sep 03, 2020
This deodorizer contains added fragrances.

Stuff leaked out onto treat bags which then made my cats not want to eat them. Lots of money spent for quality then they ship all this stuff together and it gets beat up in transit. Don’t bother buying this stuff unless it’s in person. Not the best smell either.

I switched litters and it doesnt hide the smell as well as my old litter did. Sprinkling a little and I do mean a little really helps. The litter smell is gone from the house instantly. Thank goodness for this product. I much prefer the scent of the Double Duty to the lavendar scent. Lavender doesnt smell like lavender but mens cologne.

This product is a staple in our house at this point. We have 6 cats and ZERO litter box odor. Our boxes are used with Pretty Litter, daily cleaning, and monthly litter-changes. Every time I restart the box with a full litter change, we first clean it with Natures Miracle foaming spray, sprinkle Arm & Hammer Litter Deodorizer all across the bottom, add new litter, more deodorizer, stir it in, a little more deodorizer, stir it in some more. I put my deodorizer powder in a cute glass Shaker (dollar store score!) which blends in to my shelves and holds about a third of the box. This also helps provide an even layer all over and keeps me from accidentally using too much. I scoop the poo daily and stir the pee around so its not concentrated in one spot. I add more deodorizer weekly, stirring it in each time. The scent is a little strong at first but "airs out" in just a few minutes. With this "system" we have never had pee-stained feet or any other smells. The fragrance does not bother the cats at all. It is not dusty, my cats all have silky shiny coats. I really couldnt be happier with this "routine".

I had just about given up on controlling my kitties litter box odor. I’ve tried several kinds of litter but they are very picky and the ones that control odor best, they won’t use which left me in a tough spot. I’ve tried the spray version of this but it was only OK. I didn’t like that it was a wet product. I came across this it’s been great!! I use it each time I scoop the litter box. It Immediately takes away any unpleasant odor and all you smell is the rather strong odor of this deodorizer. I sprinkle and then stir it around a bit so it’s not so strong that my cats will avoid the litter box. It’s been about a month and I’m ready to order another box, maybe i’ll order 2!

I had never used a product in the litter box before but this one made me a believer. The fragrance is not overwhelming and the baking soda really holds down the urine odor. Sometimes, this product works so well I overlook cleaning out the litter box

While this isnt a fix, it does seem to keep the distinct urine and poo smell that stays in used litter under control between the big clean outs. I sprinkle a fine layer on the top after cleaning and the kitties dont seem to mind!

It smells great for the human but maybe not the cat? It is very strong and our kitties have such a strong sense of smell that I can’t even imagine how overwhelming the smell must of been for them. We discontinued using it just so the boys aren’t bothered while doing their business.
