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.

Is this product scented or unscented?
Answer by ChewySep 03, 2020
This deodorizer contains added fragrances.

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.

Great odor control

This litter deodorizer really works. I usually throw in some baking soda with my cat litter, and that helps with overall smelliness, but if I need a fast fix to smelly litter box odors, this is what I use and I love it.

This product is the only level of deodorizer from Arm and Hammer you should buy. By itself it's okay but it doesn't produce a pleasant scent from the litter box as I expected. It barely does a good job controlling the smell. It also produced a series of sneezing fits from my cat, but that could vary from cat to cat.

box squashed to pancake

You all need to talk to packers about packing the softer items in bubble wrap to keep bigger items from smashing them to nothing , powder was smashed out of container and box was flat

Good for that stinky cat in your life

I have one of those stinky cats so this stuff is great. I usually stir it in the litter and when I scoop it, I'll shake some over the top in the trash bag. I think it's also good to let the cat know you've cleaned their box. They can smell this and know their box is clean again.

Quite strong fragrance but AMAZING results

I have four cats that use one *large* litter box (it holds wayyy more than a single 40lb bag of litter) and this is the best thing I’ve found to freshen up the smell in the house to my partners likes. I’m very nose blind but I sprinkle this in and I don’t hear anymore complaints! I use with Dr Elsey’s Clean Tracks - not the strongest odor neutralizing litter but combined with this it’s perfection.

Litter Deodorizer

I learned of this product from another kitty mom. My kitty girl and I never want to be without it in our home. Great product.

Arm & Hammer Litter Double Duty Cat Litter Deodorizer Baking Soda

This works really well at keeping the urine sent down between the days of cleaning the littler box. Even better then the regular Arm and Hammer Litter Deodorizer. Male cats always seem to have a bit more smell to their boxes. Like the product very much.

An essential item for your litter box!

I sprinkle a little bit of this into our litter box once a week. I even sprinkle it into the litter pail if it’s getting a little stinky, but it’s not garbage day yet. It masks any bad odors and keeps the room smelling fresh!! Using too much can seem overpowering so remember a little goes a long way!!

The opposite of a deodorizer: it has the worst chemical smell

I thought I was buying deodorizing baking soda. But this product does the opposite--it has that smell of a cheap chemical additive that some people use to cover up bad smells. But to me this is the worst smell in the world. I will not buy this again.

It smells nice

This incredible stuff smells so incredibly nice and it hides the smell of urine and (in Johnny Depp voice) "feline fecal matter".
