Here are some of the best cat litter deodorizers we’ll be covering:

How can I stop cat litter from smelling?

Cat ownership can be an incredibly rewarding and loving situation, but experienced cat owners know that it doesn’t come without its challenges. One of those challenges will be, more than likely, your cat’s litter, and the terrible smells that sometimes come associated with it.

New cat owners often ask the question is there anything I can do about my cat’s smelly litter? In short, the answer is yes, there are tons of options for cats whose litter box odor is rather unpleasant. 

Cleaning schedule

For starters, you’ll want to make sure you’re scooping your pet’s litter box at least once a day, preferably twice if you have the time. Your cat doesn’t like going in a box that they’ve already gone to the bathroom in and are therefore far more likely to go outside of their box instead.

If your cat has problems with going outside the box, you’ll also want to avoid automatic scoopers. These machines, while practically efficient, have been known to spook cats with their mechanical whirring, and convince them to go outside the box.

After scooping your cat’s litter box daily, cleaning them shouldn’t be too arduous. That being said, you’ll want to make sure you’re not going more than a month without thoroughly cleaning your pet’s box. This includes emptying the litter, scrubbing the sides thoroughly with soap and water, and adding new clean litter back to the box.

Another universal truth that cat owners have become accustomed to: cats love to scratch, and that’s true of their litter boxes, too. The scratch marks their claws leave are a great place for smelly bacteria to hide and cause stenches. To avoid this, try and replace your cat’s box annually.

Size and number of boxes

Keep in mind that not every litter box will work for every cat. When purchasing, ensure that the box is long enough for your cat to stand in, from the tip of their tail to their nose. Some cats will prefer open litter boxes, while others will like lidded boxes, so it can take a little bit of experimentation to figure out what your cat prefers.

Cats can often be territorial and refuse to use a litter box that another cat has already used. If you have multiple cats in your home, you’ll want to follow this simple formula for litter boxes: number of cats + 1 = number of litter boxes. In other words, that means you should have one more litter box than you do cats per home. Therefore, if you have three cats, you should have four litter boxes!


Usually, cat owners like to stuff their cat’s box in a tiny corner so their pet’s bathroom isn’t out amid the rest of their furniture. While doing this can save your guests from a nasty visual, it might be forcing a nasty smell into your home, too.

You can avoid these smells by keeping your cat’s litter box in an open area with good ventilation. Not only will this help eliminate that smell, but your cat will probably find a litter box in an open area much more comfortable.

Adding baking soda

Finally, you can also try using baking soda to try and keep the smells of your cat’s litter box at bay. Start by sprinkling a bit of baking soda beneath your cat’s fresh litter each week, which can absorb some of those nasty smells that would normally get trapped in your cat’s litter.

Remember to never use perfumes or other scented sprays next to your cat’s box. This can irritate or even harm your cat’s sensitive nose and lungs, and can seriously discourage them from using their litter box.

What is the best cat litter deodorizer?

Many “cat-brands” offer cat litter deodorizer to help reduce the smell of your pet’s box. These can be especially useful in multi-cat households that have litter box smells wafting from every corner of the house. 

Below, we’ve included reviews on some of the best cat litter deodorizer available right now!

iPettie Cat Litter Box Odor Genie 

This product from iPettie’s first claim is that they are odorless, and 100% cat-friendly, which is always important to look for in your cat’s litter deodorizer.

The iPettie Odor Genie helps to eliminate smells through the use of ozone and a negative ion generator. In other words, it’s an automated spraying process that turns off when your cat approaches the box and turns back on once they’ve left.

As long as you’re charging your Odor Genie at least once every ten days, it will work great! And, upon purchase, you’ll also receive an adhesive-backed bonus sticker to help you stick the device to a wall near your pet’s box.

I think the nicest thing about this product is the fact that it’s a one-time purchase. You won’t have to keep buying consumable spray products, and you’ll never accidentally run out of the product when you need it! On the other hand, this product is a little bit more expensive than your average consumable deodorant, so you’ll have to decide if the investment sounds worthwhile to you!

Smiling Paws Pet Organic Cat Litter Deodorizer 

This product is interesting because it claims to be a 3-in-1 pet odor eliminator and neutralizer. Not 3-in-1 like a shampoo, conditioner, body wash combination; this deodorizer eliminates unwanted scents, absorbs moisture, and releases a fresh pet-friendly smell.

If you’re worried about the potential harm these deodorants could do to your pet, you can use Smiling Paw’s deodorizer with confidence. It’s not non-toxic and biodegradable, and it’s made of all-natural American corn cub fractions.

This product is a little bit cheaper than the iPettie deodorizing product above and is sold in packs of three on Amazon. That being said, you will run out of this deodorizer eventually and will have to buy more, which is something you wouldn’t have to worry about with the rechargeable odor eliminator.

NonScents Cat Litter Deodorizer

With a 1-pack, 2-pack, 4-pack, or 8-pound bag sales option, this deodorizing product can work for any cat family, regardless of size! This is another fragrance-free odor eliminator that can be sprinkled beneath your cat’s litter to help keep the smell at bay!

Utilizing a fragrance-free product can help keep your cat safe from any harmful additives. And, as some cats will have an adverse reaction to a scented litter box, this will ensure they won’t be driven to going outside of their box.

The best thing about this deodorizer is that it can be used around the rest of your home, too. Garbage cans, trash compactors, garbage disposals, anything that might get smelly, you can use this deodorizer to keep your entire house smell-free!

Rocco & Roxie Litter Box Odor Eliminator

This Rocco & Roxie product effectively absorbs smells from even the strongest smelling litter boxes by using a proprietary blend of essential oils. This blend, in turn, neutralizes odors at the molecular level, which helps keep your cat’s box smells great for longer.

Like the NonScents deodorizer above, this product can be used for more than just cat odors. Use is for your stinky garbage cans, or even your other pet’s kennels and crates.

Fresh Step Cat Litter Crystals

Fresh Step has always been a brand known for delivering quality animal products, and their litter crystals are no exception. And, at a relatively low-price for a three-pack, this is probably the most cost-effective option included on our list.

This product is 100% non-toxic and pet friendly, so you won’t need to worry about exposing your pet to harmful chemicals. Likewise, they leave no residue and disappear over time because they’re water-soluble.

Activated carbon is a non-toxic ingredient that has been used in litter safely for many years, so rest assured that this additional ingredient in your pet’s litter deodorizer won’t cause them any harm.

How to make your cat’s litter box more inviting

Now that you’ve had a chance to look at some of the most effective litter box deodorizers on the market, we’ll share a few tips to make your cat’s litter box more inviting! If your cat loves to go to the bathroom outside of the box, try some of these tips!

If you live in a multi-cat household, you’ll have to make sure that one of your cats isn’t ambushing another while in the box. As mentioned before, cats can be territorial, and the easiest place for one cat to attack another is when they’re eliminating their waste. If your cat is attacked in the box, they’ll be less likely to return, so make sure to keep an eye on your feline friends.

Additionally, make sure that you’re not using your cat’s box as a punishment. If your cat eliminates outside of the box, don’t punish them and then place them in the box; this will make them far less likely to return to the box the next time they have to go to the bathroom.

Finally, cats eliminating outside the box might have a medical issue, such as a urinary tract infection. Always make sure your pets are in good health by paying attention to any unusual behaviors, and by taking them to their veterinarian for regular check-ups.
