To transition you cat to use Arm & Hammer Litter: * Fill a clean litter box ¾ full of Arm & Hammer Litter. Next, pour one to two inches of your old litter brand on top. Don't mix! Your cat will do this naturally as she uses her litter. * Allow your cat to use the mixed litter until the next time you change the box. * Your cat should be acclimated to Arm & Hammer after just one use, but some cats can need a little more time.
Where should the product be stored?
Store in a dry place if clumping cat litter comes in contact with water, clumps will form. But it will not be affected by humidity.
Can I use this in animal cages or in litter boxes for pets other than cats?
No, it is not recommended.
Is ARM & HAMMER™ Cat Litter antibacterial?
No. The litter box is a dirty place. Each time your cat uses the litter box, feces and urine introduce odor-causing bacteria. Although the product is not antibacterial, ARM & HAMMER™ Cat Litter utilizes genuine ARM & HAMMER™ Baking Soda to eliminate odors caused by bacteria.
Is the carton recyclable?
Yes, The package is made from 100% recycled materials with 35% from post consumer sources. It is recyclable in areas that accept this type of carton. Please check with your local recycling center for details.
Does the product contain animal by-products?
No.
Does ARM & HAMMER™ Cat Litter contain Baking Soda?
Yes, all ARM & HAMMER™ Cat Litters contain pure ARM & HAMMER™ Baking Soda.
Should I use ARM & HAMMER™ Cat Litter Deodorizer in conjunction with ARM & HAMMER™ Clumping Cat Litter?
It is not necessary to use ARM & HAMMER™ Cat Litter Deodorizer with ARM & HAMMER™ Cat Litter but using both will give you an extra boost of freshness.
Why is ARM & HAMMER™ Cat Litter Deodorizer still needed?
ARM & HAMMER™ Cat Litter Deodorizer is designed to eliminate litter box odors that ordinary scoopable and clay litters can't. The powder formula also prevents the litter from sticking to the bottom of the box, making litter box clean up even easier.
Is ARM & HAMMER™ Cat Litter dust-free?
As the package indicates, all ARM & HAMMER™ Cat Litters are 99% dust-free.
Does ARM & HAMMER™ Cat Litter track?
As with any litter, it is possible some particles may scatter outside the box when the cat uses or leaves the box. However, unlike traditional clay litters, clumping litter should not get muddy in the litter box so your cat will not leave muddy footprints or tracks outside the litter box.
What is toxoplasmosis?
Toxoplasmosis is a condition caused by a parasite sometimes found in cat feces. Wash your hands thoroughly after handling used cat litter. Pregnant women and those with suppressed immune systems should be especially careful to always do so. Unused ARM & HAMMER™ Cat Litter in its original package does not contain these parasites.
What is the pH of ARM & HAMMER™ Cat Litter?
All ARM & HAMMER™ Cat Litters are slightly alkaline.
Is ARM & HAMMER™ Cat Litter safe for pets including kittens?
We are extremely confident of the safety of ARM & HAMMER™ Cat Litter, when used as directed. During its development, ARM & HAMMER™ clumping Cat Litter was evaluated by numerous consumers (and their cats) with no adverse effects. Additionally the safety of baking soda is well known and documented.
Can ARM & HAMMER™ Cat Litter cause Feline Urinary Syndrome (also known as a urinary tract blockage)?
Feline Urinary Syndrome (FUS) is a common condition that especially affects male cats. Although there are many theories on what causes or contributes to FUS, there is no indication that clumping (or traditional clay) cat litter causes FUS in cats or kittens.
What is the source of ARM & HAMMER™ Cat Litter ingredients?
The main ingredients in ARM & HAMMER™ Cat Litter are derived from mineral and plant sources.
Does ARM & HAMMER™ Cat Litter expire after a period of time? What is the shelf life?
ARM & HAMMER™ Cat Litter does not lose its effectiveness over time.
How long does a box or bag of ARM & HAMMER™ Cat Litter last?
The amount used varies depending on the frequency of litter box usage as well as the number of cats in your household.
How often should I change the Cat Litter in the litter box?
The frequency with which your cat uses the litter box and the number of cats that use the litter box will determine how often the litter box should be changed. Some consumers change their litter box on a regular schedule (every few days, or weekly, or on trash day, etc.), others change it when it looks wet or when odor is noticeable. Remember, as your cat uses the litter box, scoop out soiled clumps and solids. After you remove the odor clumps and solids, replace the discarded litter with a sprinkling of fresh litter, making sure to maintain at least 3-4 inches of litter in the box.
What if my cat eats the litter?
It is not normal for a cat to eat cat litter and it may be a sign of illness. Your veterinarian should be contacted immediately. (Please be assured that should a small amount be ingested during normal grooming, your cat's intestinal tract should naturally move the material through the cat's system.)
What if my dog eats the litter?
Although dogs sometimes eat cat litter and other foreign objects, you should remove the litter box from your dog's reach and contact your veterinarian immediately. Ingestion of litter and foreign objects may indicate illness.
What is Clumping Litter or Scoopable Litter? How does it differ from traditional Clay Litters?
Clumping or scoopable litters utilize the "clumping" properties of sodium bentonite, a naturally derived special type of clay, to control litter box odors. This special type of clay uses the moisture it absorbs to bond soiled litter particles into clumps for easy removal and disposal. Litter boxes using clumping litters can be cleaned by removing only the soiled litter and sprinkling a new layer of clumping litter in the box. The box is fresh for use without the unpleasant task of emptying, washing and drying! Ordinary clay litters can absorb moisture, but cannot isolate it for easy removal. Since soiled litter is a source of odor-causing bacteria, clay litter must be completely changed frequently to prevent odor build-up. This involves discarding the entire contents of the litter box, washing and drying the box, and replacing the litter-a messy and smelly task... Cats love a clean litter box and nothing is cleaner than fresh clumping litter. Cats think clumping litter is the best thing since catnip...we think you'll agree!
Can ARM & HAMMER™ Cat Litter be used for traction during icy conditions?
No. ARM & HAMMER™ Cat Litter, as well as other clumpable or scoopable litters, should not be utilized for ice traction.
How does ARM & HAMMER™ Double Duty Clumping Litter differ from other ARM & HAMMER™ Cat Litter?
ARM & HAMMER™ Double Duty is the only clumping litter with a formula that combines moisture activated ARM & HAMMER™ Baking Soda crystals with urine and feces odor neutralizers to destroy both overpowering odors on contact.
What are the ingredients in ARM & HAMMER™ Double Duty Clumping Litter?
ARM & HAMMER™ Double Duty contains clay for absorbency, clumping and deodorization. It also contains powerful compacted ARM & HAMMER™ Baking Soda crystals for deodorization, as well as a fresh scent fragrance that is activated when it comes in contact with moisture.
Is ARM & HAMMER™ Double Duty scented or unscented?
ARM & HAMMER™ Double Duty has a fresh scent that refreshes every time your cat uses the litter box.
Can ARM & HAMMER™ Double Duty Clumping Litter be used in multiple cat households?
Yes, ARM & HAMMER™ Double Duty’s powerful feces odor neutralizers are designed to work for multiple cats.
How should I dispose of the litter?
You should dispose of the used litter in the trash. Do not flush litter in the toilet or place it in the drain.
Hardworking Litter for Your Cat
Every scoop of Arm & Hammer Cat Litter combines odor-absorbing clay and Arm & Hammer Baking Soda to lock in odor so your house won’t smell like a litter box. These 99% dust-free, low-tracking formulas are made to stay in the box and clump up hard to make scooping an absolute breeze. Available in scented or unscented and single or multi-cat formulas so you can find the purr-fect litter for your needs.
Litter Box Maintenance
For an odor-free home and happy kitties, follow these tips for good litter box management:
1. Fill with Arm & Hammer Cat Litter to a depth of 3-4 inches. This gives cats enough room to dig and makes scooping easier.
2. Scoop daily, making sure you get all the clumps and solid waste.
3. Refill the box to a nice 3-4 inch depth. Your feline and your elbows will thank you!
4. Throw away the used litter in the trash only. It protects waterways and your plumbing.
A Trifecta of Odor Control
Arm & Hammer Litter controls odor in three ways:
ODOR ELIMINATORS + BAKING SODA: Odor eliminators + Arm & Hammer Baking soda neutralize odors so they can’t waft through the house.
HARD CLUMPS: Litter forms rock-hard clumps that lock in odor and won’t crumble, so you can get all the waste out when you scoop.
MOISTURE LOCK: Super-absorbent clay granules lock in moisture, so urine odors can’t escape.

Scented or Unscented?
Whether you and your feline friend prefer a pleasant scent or fragrance-free odor control, Arm & Hammer has a formula for you. Choose between 5 odor-locking formulas and give your kitty the freshness he deserves!

Very Disappointing
By Kittkatt on Oct 4, 2020
I was in desperate need of cat litter during the shortage and it seemed as though I couldn’t find my regular litter which is Arm & Hammer Double Duty. So I substituted with the Arm & Hammer Ultra Duty. I figured it was made by the same company so it should be just as good. It didn’t even come close!! Sure it clumped great but it didn’t absorb the odors. With my regular litter formula you can never smell the cat box. Most people don’t even realize that there’s a cat litter box in the house unless they actually see it. But with the Ultra Duty formula, well lets just say that everyone could tell the moment they came into the house. I hated it so much that I actually ended up using the second box I was in desperate need of cat litter during the shortage and it seemed as though I couldn’t find my regular litter which is Arm & Hammer Double Duty. So I substituted with the Arm & Hammer Ultra Duty. I figured it was made by the same company so it should be just as good. It didn’t even come close!! Sure it clumped great but it didn’t absorb the odors. With my regular litter formula you can never smell the cat box. Most people don’t even realize that there’s a cat litter box in the house unless they actually see it. But with the Ultra Duty formula, well lets just say that everyone could tell the moment they came into the house. I hated it so much that I actually ended up using the second box to absorb an auto fluid spill because I refused to have it in the house. I have never been disappointed in an Arm & Hammer product before this and it was definitely surprising. I will never buy this formula again, not even in an emergency. … more

Doesn't control odors
By Emma on Nov 10, 2020
I wanted to try a new litter to see if there were any other brands that did a better job than my current litter, so I tried Arm & Hammer. That was a mistake. Our entire house smelled terrible! It did not control any of the odor. I feel like it made the smell worse. I will never be buying this again.

Good Litter
By KimD on Sep 15, 2020 Top 10 Contributor
I have had cats for 30+ years so I have used almost every litter on the market at some time. I have 4 cats and 1 ginormous litter box that holds about 35# of litter. People tell me that you would never know I even had 1 cat because you never smell the litter in my home. I do have a favorite litter but will buy any brand if that is not available or I find a good deal. I have used this litter many times and would buy again. I keep one auto ship for litter, one for all other things. I seldom have shipping damage that way.

I love this litter
By porcelina68 on Sep 11, 2020
I have tried all kinds of cat litter over the years, and this one is the best, in my opinion! If I let the box go a couple of days, I don't smell it! Perfect!!!

Great Product but delivery could’ve been better
By Lexi on Jun 12, 2020
This product is great. I have two cats and a small bathroom, doesn’t smell bad and doesn’t smell to strong or like perfume ! The delivery person however, left it at the bottom of my staircase this time and the box was smashed in ... that’s why I pay through here with the delivery fee and it’s only one flight of stairs and the first delivery I got they brought it right up to the door.

Arm & Hammer Double Duty and Multi Cat
By Jan1 on Jun 14, 2020
I have used Arm & Hammer products for years and have always found them very satisfactory. I have never seen any cat litter turn to mud. Arm & Hammer litter comes in unscented also, which is what I use, if you are sensitive to the scented version. It clumps just fine. There is also a low dust version. I will always use Arm & Hammer.
