Questions & Answers

17 Customer Questions

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.

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 are the actual ingredients used in this product? I require this knowledge before exposing my animals to it.
Answer by ChewyOct 18, 2020
This deodorizer is made from Sodium Bicarbonate, Hydrated Silica, and Fragrances.

Is this product scented or unscented?
Answer by ChewySep 03, 2020

Great product, poor transport

The 2 cardboard boxes I ordered were crushed from top to bottom, difficult to handle and feel like you’re going to lose your grip on the box when used. The contents appear to have sunk to the bottom of the boxes. They were surrounded in cellophane to secure the powdered contents, which also reflected the crushed condition of the boxes. So unlike Chewy with whom I’ve done business for a long time. Won’t be buying this product from Chewy again. Otherwise, enjoy and appreciate doing business with Chewy and will continue to do so.

works amazing

This product has solved all of my litter box smell issues!! I live in a studio apartment, so one of my biggest challenges is keeping the smell of the litter box at bay in between scooping. I have tried other litter deodorizers in the past that haven’t really done much of anything for me. This almost completely masks any odors, even when I am up close to the box emptying the waste tray. My cats don’t seem to mind it at all. I added it before adding the litter to the box, and then added another small layer to the top of the litter. I have not had to add any more to the box in over a week and it is still masking the smell (I have an automatic litter box that is meant to go days without changing/adding litter - please try to scoop yours daily if you have a regular box!). Will definitely be buying this over and over again.

great item for small price

I've been using this for about a week with my 18-week-old kitten. No problems. I don't overuse it but put some in before starting a new litter box and then sprinkle some now and then on top, and mix n. He has no issues with it and the fragrance is so natural, yet it seems to keep the litter box from smelling. I DO scoop twice a day though. I have only one cat but unsure what the Double Duty means.

A great assist

This litter deodorizer is a great companion to any litter box. I have multiple cats and use this between litter changes to help control odor and get a little more life from my litter.

Great Product!

We have multiple cats. They refuse to use scented litter. While our regular unscented litter controls odors pretty well, this product helps it last longer. Our cats love it!

Helpful For Smell

I wouldn’t say this is end all be all, but it definitely helps mask some of the scent but don’t expect it to completely cover the smell of the litter

essential for cats

This litter box powder is amazing for controlling odors. I use it at the bottom of the box and it helps control the urine smell. I never go without it!

Best way to freshen the litter box

I normally pick this up if I’m out shopping but I received this one I ordered from chewies and I like the larger size. The smell is not over bearing and it sure makes the room smell a lot better.
