Clump & Seal. Slide. Double Duty. Super Scoop. Cloud Control. Naturals.
Six boxes on the same shelf, all orange, all promising odour control, all sounding roughly identical.
The differences are genuinely real, though, and one of them solves the specific bit of this chore that everyone complains about.
- Arm & Hammer is made by Church & Dwight, which has produced baking soda since 1846.
- Clump & Seal uses moisture-activated microgranules plus baking soda and claims up to seven days of odour control.
- Slide has a non-stick EZ Clean coating so used litter does not cement to the bottom of the litter box.
- Arm & Hammer Naturals is corn-based rather than clay, making it lighter, biodegradable and much lower in dust.
- No litter formula fixes odour in a box that is not scooped daily, regardless of the odour-control claim on the box.

What each formula actually does differently
The names are close to meaningless from the shelf, so here is what separates them in practice.
- Clump & Seal adds moisture-activated microgranules that form a seal around waste, on top of the baking soda. It is the strongest odour formula and the right pick for a multi-cat box.
- Slide coats the granules so used litter releases from the pan instead of cementing to it. It targets the cleaning chore rather than the smell.
- Double Duty prioritises clump strength against both urine and solid waste, so clumps survive the scoop intact.
- Super Scoop is the plain, unscented workhorse. The safest choice for a cat with opinions.
- Cloud Control is the low-dust clay formula.
- Naturals is corn-based rather than clay entirely: lighter, biodegradable, much less dust, softer clumps.
How the baking soda part works. Litter box smell is mostly ammonia, produced as bacteria break down urea in cat urine. Sodium bicarbonate neutralises acidic odour compounds rather than perfuming over them, which is why it works without a heavy fragrance. Church & Dwight has been making baking soda since 1846, so this is the one brand where the ingredient is genuinely the company’s core competence.
The honest limit. No formula fixes a box that is not scooped. Seven days odour-free assumes daily scooping and a box changed on schedule. Odour control buys you margin, not permission to skip.
Scented or unscented, and why it matters
This is the choice most likely to cause a problem, and most people get it backwards by picking the strongest fragrance available.
A cat’s sense of smell is far more acute than ours. A fragrance that reads as pleasantly fresh to you can be overwhelming at nose level inside a covered box. Litter box avoidance is one of the most common behavioural complaints owners have, and litter type and scent are among the usual causes.
Start unscented. Super Scoop is the unscented option here. If odour genuinely beats you after honest daily scooping, move to Clump & Seal. Do not start at maximum fragrance and work backwards, because by then your cat may already have chosen a new spot.
And if a cat who reliably used their box suddenly stops, treat that as medical first. Urinary tract disease, kidney problems and arthritis all present as box avoidance, and the ASPCA covers the behavioural side once a vet has ruled out illness. Our guide to a cat not using the litter box goes through the causes in order.
The 6 Arm & Hammer products, reviewed
Arm & Hammer Litter Clump & Seal Multi-Cat Scented Clumping Clay Cat Litter, 84-lb bundle: best overall
Clump & Seal Multi-Cat is the formula the brand is known for, and the right default. Moisture-activated microgranules seal around waste and the baking soda handles ammonia, with the label claiming up to seven days odour-free. In a multi-cat box that gets worked hard, this is the one that keeps up.
Arm & Hammer Litter SLIDE Easy Clean-Up Clumping Cat Litter Non-Stop Odor Control, 84-lb bundle: best for easy cleaning
Slide is the genuinely clever one. Its EZ Clean coating stops litter cementing to the bottom of the pan, so waste slides out instead of needing a scraper. If the part of this chore you actually hate is chiselling a stuck clump off the base, this fixes exactly that.
Arm & Hammer Litter Super Scoop Unscented Clumping Clay Cat Litter, 120-lb bundle: best unscented
Super Scoop unscented, and the safer choice for a fussy cat. Cats have far more sensitive noses than we do, and a heavily perfumed litter is a common reason a cat quietly stops using the box. Start here if yours has ever been particular.
Arm & Hammer Litter Double Duty Scented Clumping Clay Cat Litter, 120-lb bundle: best hard clumps
Double Duty is built around clump strength, targeting both urine and solid waste odour. Clumps that hold together on the scoop mean less litter wasted and a box you can empty completely far less often.
Arm & Hammer Litter Naturals Scented Clumping Corn Cat Litter, 36-lb bundle: best natural option
Naturals is corn-based rather than clay, which is a real departure for this brand. Lighter to carry, biodegradable, and much lower dust than clay. Clumping is softer than the clay formulas, so scoop with a gentler hand.
Arm & Hammer Litter Cloud Control Platinum Multi-Cat Clumping Cat Litter with Hypoallergenic Light Scent, 37-lb box: best for dust
Cloud Control Platinum is the low-dust clay formula, which matters if a cat or person in the house has asthma. It is not dust free the way pellets or plant litters are, but it is a clear improvement on standard clay at a fair price.
How it compares
- Against Tidy Cats: both mainstream clay brands at similar prices. Arm & Hammer edges it on odour control, Tidy Cats has the Breeze pellet system as a genuine alternative.
- Against premium clay: comparable performance for less money. This is a value pick that does not feel like one.
- Against plant litters: clay clumps harder; plant litters are lighter, biodegradable and far less dusty. Naturals is the bridge if you want to try corn without leaving the brand.
- Weight is the real drawback. Clay is heavy, and a 40-lb box is genuinely difficult if you carry it upstairs.
Who should buy Arm & Hammer
Buy it if you want strong odour control from a widely stocked clay litter at a fair price. Clump & Seal for a busy multi-cat box, Super Scoop if your cat is fussy, and Slide if scraping the pan is the part you dread.
Skip clay altogether if dust or weight is your issue, and look at plant options like Naturally Fresh or Sustainably Yours. Compare the whole field in our best clumping cat litter guide.
The bottom line on Arm & Hammer
Baking soda odour control from the company that has made baking soda since 1846, at mainstream prices, in formulas that genuinely differ once you know what to look for.
Slide is the underrated one if you hate scraping the pan, and Super Scoop is where to start with a fussy cat. Whatever you pick, scoop daily, because no formula substitutes for that. Arm & Hammer Litter Clump & Seal Multi-Cat Scented Clumping Clay Cat Litter, 84-lb bundle is the default. This article is educational rather than veterinary advice.
Frequently asked questions
Q: Is Arm & Hammer a good cat litter?
Arm & Hammer is a strong mainstream clay litter with genuinely effective baking soda odour control at a fair price. Clump & Seal is the best formula for multi-cat homes and Slide solves litter cementing to the bottom of the pan.
Q: What is the difference between Clump & Seal and Slide?
Clump & Seal adds moisture-activated microgranules that seal around waste for maximum odour control. Slide adds a non-stick coating so used litter releases from the pan instead of cementing to it. Clump & Seal targets smell, Slide targets cleaning.
Q: Does Arm & Hammer litter really control odour for 7 days?
The seven-day claim assumes daily scooping and changing the box on schedule. Baking soda neutralises the ammonia produced when bacteria break down cat urine, but no formula controls odour in a box that is not scooped.
Q: Who makes Arm & Hammer cat litter?
Church & Dwight, the company founded in 1846 by Dr. Austin Church and John Dwight, which has produced baking soda ever since and now applies it across household products including cat litter.
Q: Should I buy scented or unscented Arm & Hammer litter?
Start unscented with Super Scoop. Cats have a far more acute sense of smell than people, and strong fragrance inside a covered box is a common reason cats stop using it. Move to a scented odour formula only if unscented cannot keep up.
Q: Is Arm & Hammer Naturals better than the clay litters?
Naturals is corn-based, so it is lighter, biodegradable and much lower in dust than the clay formulas. Its clumps are softer, so it needs a gentler scoop. It is the better pick if dust or weight is your main concern.
Q: Is Arm & Hammer litter dusty?
The standard clay formulas produce normal clay dust. Cloud Control is the low-dust clay option and Naturals is lower still because it is corn-based. Pouring slowly from a low height cuts most of the dust you actually breathe.
