The Best Cat Litter For Odor Control (2021 Reviews)

Are you looking for the best cat litter for odor control that will actually do what it says it does?

Litter box odor is one, if not the main, nuisance of cat ownership. Your guests will know the second they walk through the door because a whiff of cat piss is hard to miss! But did you know that our feline companions are among those with the most efficient kidneys in the animal kingdom?

A cat’s Loop of Henle does an exemplary job at squeezing out every last drop of absorbable water, discarding all toxins out of the system where it gets collected into the bladder. This makes cat urine highly concentrated and fetid. Male cats that have not been neutered have the added effect of testosterone, making their urine smell worse.

On the bright side, keeping the litter box odor situation under control is mostly a matter of choosing the right litter and keeping the litter box clean. If you choose the best cat litter for odor control, scoop daily, wash the litter box and surrounding area regularly, and feed your kitty right, then litter box odors should not be a problem.

Best Cat Litter For Odor Control (Clumping Cat Litters)

Arm & Hammer Clump & Seal Platinum Cat Litter – Editor’s Pick

The Arm & Hammer Clump & Seal Platinum is hands down the best cat litter for odor control. If you are hesitant about this product’s price point, let me explain to you why it is worth every dollar.

The product comes in a sturdy cat-proof cardboard box with a strap handle, which makes it a cinch to transport, pour, and store. Once you pour some into the litter box, you will see that the litter is lightweight and ultra-fine. The consistency resembles that of golf course bunker sand, which means it sifts effortlessly without having to shake the litter sieve.

As you may already know, Arm & Hammer is notable for its world-famous baking soda that locks and eliminates odors exceptionally well. Utilizing the company’s patented formula along with other heavy-duty odor eliminators, Arm & Hammer successfully produced the best cat litter for odor control.

Clump & Seal Platinum uses moisture-activated Micro-Granules that immediately react to wetness, clumping around putrid wastes to form a tight seal. It will only take a few moments for the clumps to form into rock-solid balls, and whatever excess will simply fall away to be used for a later time.

Highly effective, it wastes very little litter and tends to go farther. Therefore, the Clump and Seal is more economical than cheaper brands that force you to throw out litter more often due to their ineffectiveness and poor odor control. Also, the litter does not run down and stick to the bottom of the litter box, unlike many other brands.

When it is time to change and wash the litter box, the fine granules of the Arm & Hammer makes it easier to take out since they don’t glue to the box when damp. While you need to scoop daily, a single-cat household can go three weeks between washings.

Arm & Hammer claims that their product is 100% dust-free, and many cat owners happily agree. Satisfied customers say that the litter reduced their need to dust the house. I have yet to see a litter in existence that would not get tracked, but at least the Clump & Seal Platinum cat litter rarely stick in the paws of our whiskered friends. Given the formula is made, it makes it a lot more manageable to sweep up anything that is tracked.

The hardened clumps are easy to scoop and the litter doesn’t stick to the litter box, making it easy to wash

Fresh Step Advanced Extreme Scented Cat Litter

This particular clumping cat litter by Fresh Step is our second best cat litter for odor control. While the product is designed to leave behind a pleasant scent, it does more than just mask kitty wastes with perfume.

Employing Febreeze’s odor-eliminating tactics, it inhibits bacterial growth for up to 10 days at a time, keeping the stench at bay. What I find most interesting about this product is its “paw-activated fragrance.” The crisp mountain spring scent is emitted each time your kitty rustles up the litter.

Most importantly, the litter does a great job of clumping an entire pee puddle so that the litter box doesn’t reek of ammonia. While the hardened clumps don’t turn out to be as robust as those produced by the Arm & Hammer, nonetheless it stays intact for easy scooping.

Moreover, this cat litter keeps the dust to a minimum when pouring and scooping. Dust-wise, it is not quite to be on the same standard as the Arm & Hammer. Many consumers expressed their opinion that this product could have been the best cat litter for odor control if the manufacturer has made improvements regarding dust control.

What I don’t like about this product is that it leaves sticky residues on the sides, which feels like scraping cement on plastic. Another thing to note is that this product is not 100% non-tracking. So, you may want to use a top entry cat litter box so that your feline companion won’t throw away the litter everywhere.

In the end, you can’t hold those against it because the level of freshness this cat litter offers is excellent. The product is also modestly priced, given that it is from an established brand that has partnered with another household name.

Purina Tidy Max With Glade Clean Blossoms Cat Litter

Similar to Fresh Step and Febreeze, Purina and Glade have also teamed up in pursuit of creating the best cat litter for odor control.

The odor-busting formula of Purina Tidy Cats attacks the three main sources of odor – urine, feces, and ammonia. According to the manufacturer, the Ammonia Blockers inhibits the litter box from reeking ammonia smells for up to two weeks when used as directed. Meanwhile, the addition of Glade masks odors and makes the vicinity of the litter box smelling clean and fresh.

As for the freshness and strength of the fragrance, I would give it a higher score than Fresh Step. The scent is not obnoxiously overpowering, but it lingers around. You would think there was a bottle of Glade air freshener somewhere in the room rather than a used litter box.

Moreover, this cat litter comes with moisture-activated Power Pieces that instantly absorb wetness on contact. This feature helps maintain dryness throughout the litter box so that the kitty next in line is comfortable doing its business.

Another fabulous feature I like about this cat litter is that it does not create clouds of dust during pouring and scooping. The formula is also lightweight, which makes it easier to store and carry around. Although it is light, it packs a punch in how much it can absorb.

So, what’s the catch? The kicker is that this product falls a little short in the clumping action. Still, that does not necessarily mean there will be little crumbs of wet litter that might fall off as you scoop.

The biggest downside is that urine can somehow pass through the litter and reach the bottom where it creates tiny clumps if your kitty pees a lot. Hence, I recommend filling the pan with two to three inches of litter so that the litter will clump and seal in the liquid before it reaches the bottom.

Best Cat Litter For Odor Control (Silica Crystals)

Ultra Micro Crystals Cat Litter

If your pampered feline is unhappy with clumping clay litters or wood shavings, you might want to give the Ultra Micro Crystals a shot. This cat litter is on the expensive side, so you need to stretch your budget a little. Regardless, the clear trade-off is that you will not be dealing with dust and fumes that the majority of conventional litters put out.

As the name hints, the Ultra Micro Crystals cat litter is designed with micro silica gel beads that render an almost sand-like consistency. This type of litter takes up 70% less landfill contribution compared to standard substrates. In other words, you are doing Mother Nature a favor!

Since the beads are so tiny and lightweight, it can get messy around the litter box if your kitty has bad bathroom habits. That is why it is important to train your kitty starting from a young age so that there is little chance that you will be dealing with such problems.

On the bright side, odor is not a huge concern because the product dries out the wastes. The beads effectively sap the moisture from both the urine and feces, sealing pungent odors for several days. Keep in mind that you still need to rake out cat poop every day. Unlike clumping litter, silica crystals don’t conceal those little brown doo-doos.

As for cleanup, you just need to rake out and dispose of exhausted crystals, followed by stirring the beads so those at the bottom are brought to the top. Moreover, remember that this product is for a single-cat use only.

Doesn’t cover up unsightly feces

Best Cat Litter For Odor Control (Biodegradable Substrates)

It’s A Tea Potty! Hinoki Wood & Green Tea Natural Cat Litter

If you are looking for a clumping cat litter that features a biodegradable formula, then look no further. Using potato starch, this cat litter creates pee balls that you can dispose of by flushing. The clumps might be a bit gooey if you remove them immediately from the litter box, but they will remain intact if you remove them with gentle sifting actions.

Cat poop, on the other hand, is a different story. However, don’t sweat it if your kitty poops during your absence. After some time, the Hinoki and green tea will neutralize the odors. As long as you scoop the soiled litter every day, you can remove the clumps without leaving a mess in the pan.

Moreover, the formula is dust-free, and the tracking is minimal. Your cat might drag a few granules within two feet from the litter box, but that’s about it. Best of all, this product is biodegradable. By choosing this cat litter, you can be sure that you are not adding another stressor to the environment.

Feline Pine Platinum Cat Litter With Arm & Hammer Baking Soda

Feline Pine Platinum cat litter is a smart choice for the health of your whiskered friend. If you are wary of fragrances, then you will be happy to know that this cat litter does not contain synthetic ingredients. Likewise, its formula keeps dust to a minimum.

While it is half the weight of clay litter, it can last three times longer than clay litter per pound. Like thousands of mini sponges, the pellets absorb liquids to eliminate ammonia buildup. Combined with Arm & Hammer baking soda, it combats strong odors caused by bacteria.

Feline Pine is lightweight, making it easy to clean up after your kitty. If you have a flower garden, you could also use the litter as fertilizer.

Although this product is all-natural, you don’t have to worry that its production has cost thousands of trees. Feline Pine is made using reclaimed lumber shavings.

How To Pick The Best Cat Litter For Odor Control

Thankfully, litter manufacturers have graced us with several solutions to fight bad smells and breathe new life into our home.

Read on to learn what important factors are worth considering when choosing the best cat litter for odor control.

Clumping Litter Vs. Non-Clumping Cat Litter

There are many reasons why cat owners mostly prefer a clumping litter. Among these advantages include its exceptional ability to combat tough odors. Clumping cat litters designed for odor control have an active ingredient that inhibits the buildup of odor-causing bacteria, such as activated charcoal and baking soda.

Clumping cat litters work by absorbing urine and feces and forming them into hard lumps that you can scoop up at a later time. Since the litter will only clump around moisture, you don’t need to toss all the contents inside the litter box. As a result, it is more economical than non-clumping variants. Another significant benefit of clumping litters is that it minimizes the chances of urine-soaked litter to stick onto your cat’s paws.

However, I do not recommend clumping cat litters for four-month-old kittens and younger ones. Clumping cat litters contain sodium bentonite, which may lead to intestinal blockage when ingested. Baby cats are ever curious and might nibble some of the litter.

Regrettably, the majority of non-clumping cat litters are inferior when it comes to odor control. This type of litter accumulates ammonia quite fast. As a rule, you have to dispose of soiled bedding immediately. Then again, non-clumping litters come in a wide range of formats.

A few types of non-clumping litters use plant-based substances that are recognized for their exemplary odor control abilities. Among the popular ones include wood, grass, and corn. These substrates are highly absorbent and trap odor for a short period. The main selling points of natural substrates are their biodegradability and safety.

Cat litters are also available in silica gel crystals, which have a knack for soaking up liquid 40x their size. However, this type of litter is often expensive.

Fine Litter Particles

Given that cats our pampered felines originated in the desert, it makes absolute sense that they prefer to eliminate and bury their waste in the sand or something similar, such as clumping cat litters. Finer particles also make their paws feel better. Don’t we all love walking barefoot on soft sand rather than a rocky coast?

Low Dust and Low Tracking

A low dust formula is vital not only to keep your floors free of dust, but it also prevents you and your cat from inhaling allergens that could trigger asthma. Likewise, you want your cat’s litter to stay where it should be, not get tracked around the home.

Scented Vs. Non-Scented

The use of fragrance in cat litter remains a moot point in the cat owner community, but what does research say?

According to a recent study that was published in the Journal of Veterinary Behavior, some cats prefer scented litter, while others don’t. Simply put, every cat can be different!

If your kitty prefers a scented litter, it should be one that your whiskered friend prefers, not what you think is pleasant. Since cats have a strong sense of smell, be sure not to choose a heavily scented product that might deter your feline companion from using its litter box.

Then again, some vets and animal experts oppose the use of fragrance in cat litter. When faced with conflicting evidence and opinions, what conclusions can draw? Hence, it all boils down to personal preference. Your feline companion can’t give you a written or verbal reply, and so, it is up to you to check for signs of dissatisfaction.


The Arm & Hammer Clump & Seal Platinum cat litter has every quality any cat owner would want. As expected of the best cat litter for odor control, it shines with its antibacterial and antimicrobial properties. At the same time, it neutralizes odors without the use of artificial fragrances that put off some cats. This product holds a high bar that others should be measured.

If you prioritize training, consistent hygienic practices, as well as use the right tools, you are almost guaranteed to end up with a well-mannered kitty and an odorless home.
