The Best Cat Litter Deodorizers

The dreaded cat litter, a necessary evil? Not anymore. Thanks to the great advances over the decades, there have been plenty of tools created to help control odor from cat litter. Litter deodorizers help remedy the smelly issue by either neutralizing the scent altogether or masking it with a much more pleasant fragrance. In order to find the best little deodorizer for you and your furry friend, there are a few questions we asked ourselves: does it eliminate the odor or mask it? How long will it last? Is it strong enough for multiple cats? Our favorite deodorizer was the Litter Genie Plus Pail, which kept the dirty litter tightly enclosed to trap the smell. It also was built to last and holds nearly 20 pounds of waste. But if you're looking for an option to use on the litter until it's time for clean-up, take a look at NonScents Cat Litter Deodorizer which neutralizes odor upon contact and lasts weeks at a time. Keep reading for a detailed guide on the best litter deodorizes on the market today.

Storing cat litter in a container is convenient for the fast removal of smells. The main advantage is that you are not simply spraying a substance over the litter tray to mask odors, rather removing the source of the problem completely. The design makes it easy to clip the bag and empty again requiring little effort to operate. The refill lasts ten weeks for one cat so it is ideal for owners who have busy lifestyles. Once full, the bags are clipped off, so the smell isn’t released back into your home.


  •  The bags that come with this litter container are extremely durable. Holding up to 19 pounds of waste, you can feel confident that they won’t break during clean-up.
  •  This choice also features a sturdy scooper that will last you quite some time. The handle is solid, a bit longer, and the scoop is coated with Teflon so nothing sticks to the surface.


  • This device is more of a temporary holding measure rather than a finite solution.

What Really Matters

Removal of Foul Odors

While cats provide companionship and are treasured members of the family, the fact remains that as living creatures they will excrete waste. Dealing with cat waste material is one of the realities of being a pet owner, and as they usually do so indoors via a litter tray, it can create some strong and unpleasant smells.

The whole purpose of cat litter deodorizers is that they work to remove or at least reduce unpleasant odors produced after your cat has visited their litter tray. The removal can be physical in the form of a storage container to be emptied at a later date. Alternatively, you can also neutralize or mask the smell using a litter mix or spray.

Removing smells is important not least because you want your home to smell clean and fresh. As litter trays are often placed in the kitchen, it can create a putrid aroma if the smells are not neutralized effectively. So, when selecting a cat litter deodorizer, the removal of odors is a top priority.

Product Type

As previously touched upon, there are different types of cat litter deodorizers. Firstly, you need to think about whether you want a device that stores the cat litter away from the tray or if you want a product that sprinkles directly into your existing litter mix that works when it comes into contact with waste matter. Some brands create their cat litter with an inbuilt deodorizer, which is convenient as it stops the odors at the source rather than reacting afterward with a spray or storage device.

Great Scent

While the main goal of a cat litter deodorizer is to remove unpleasant smells, scent, in general, is a very personal thing. Everyone prefers a different scent type and strength, so keep this in mind when making your choice. For example, do you want the product to have a floral scent similar to that of a plug-in fragrance device? While this may be pleasant to some, you also have to consider whether your animal would like it, especially if it contains many heavy, synthetic chemicals.

Other formulas work to neutralize the smell without adding a detectable scent on top. For those who are sensitive to smell (such as those who suffer from migraines) this type of formula might be more suitable. In addition, removing the waste from the equation via a storage facility is also a method of neutralizing smells without having to add a fragrance in to do so.

What’s in Right Now?

Given the global shift across most industries to move away from harmful chemicals and excessive plastic in packaging, it’s perhaps no surprise that when it comes to cat litter deodorizers, owners are favoring natural alternatives–baking soda and charcoal, for example, both of which are natural substances and are also commonly used in hygiene products such as in toothpaste.

The main advantage of using natural formulas for your cat is the overall creation of a more pleasant experience. Your cat has strong scent receptors and if the human finds that the smell of the deodorizer is heavily fragranced, this will be even more so for your cat. Wherever possible, natural ingredients should be chosen to help the environment.

Frequently Asked Questions

What are the benefits of using a cat litter deodorizer?

If your current cat litter mix isn’t protecting your home against unwanted smells, then the benefits of using a cat litter deodorizer are that it will remedy this. It’s important to address the issue as it’s unpleasant for everyone who is in close proximity to the litter tray–including your cat. If smells continue to build, this can encourage flies. It can be difficult to remove foul odors even with ventilation. By getting on top of the problem, you can ensure your home smells clean and fresh.

Is it better to use an inbuilt cat litter deodorizer or use a separate one?

If you tackle the source of the problem, there isn’t the need for an additional product. However, if you are happy with your current cat litter and it doesn’t have a deodorizer, you may be apprehensive to switch. After all, your cat needs to be comfortable using it and you are the one who cleans it up. The good news is that many brands have expanded their range to feature formulas that have an inbuilt deodorizer. Some cat owners may prefer to have a separate product in case the original runs out or fails to work adequately.

What other steps can I take to reduce the smell of my cat litter tray?

It’s recommended that you change your cat litter mix every ten to fourteen days. If the smell is a concern, then it makes sense to increase the frequency at which you replace the litter mix. If you have multiple cats, it’s even more important to keep on top of this, especially if they don’t have separate trays, which ideally, they should have to avoid territorial issues.

Other than switching your cat litter to include a deodorizer in the formula, there are some other steps you can take. If your litter tray is currently placed in a prominent area of the home, then moving it elsewhere (ideally where there is a lot of ventilation) can aid in reducing odors.

While dealing with litter trays is a downside to being a cat owner, it can’t be ignored. Regular cleaning and disinfecting of your home is the best way to prevent odors of all origins.
