Let’s face it, cat litter boxes stink! Especially when they’ve had a number 2.

Anything you can do to improve that is a good thing. So, in this article, we’re going to look at the best cat litter deodorizers.

The Problem With Most Cat Litter Fresheners

The problem with most cat litter freshers is that they don’t work.

Instead of neutralizing smells, they try to overpower them with a ‘nicer’ smell.

There are a couple of issues with this;

  • They make the litter tray smell worse: At best, they smell so strong (they’re often floral), they’re just as bad as the smell they’re supposed to cover up. At worst, their smells mix. Instead of covering the smell of poo with flowers, they create a smell, we call ‘Pooflower’. No one wants their homes to smell of pooflower!
  • They can put your cat off using their litter tray: Cats don’t like the smell of litter fresheners either. This can (and often does) put a cat off using their litter tray

Why Trust Us?

Our pet carers have been scooping and cleaning litter boxes since 2013.

We know, first-hand, what a smelly and mucky job it can be.

It’s not just our own experience we lean on either. Because we’re ‘in the industry’, we get to talk to and consult with;

  • Our pet-owning clients
  • Other pet carers
  • Pet trainers and behaviourists
  • Vets, and 
  • Local as well as national cat charities

As a result, we’re in a unique position to test and review pet products. Both from a pet owner, and professional perspective.

We’ve tested all kinds of products too!

From cat litter to litter boxes, to the best cat litter scoops, bins, mats and even hidden litter box enclosures.

How We Picked Which Products to Test

Choosing which products to test was easy enough. To come up with our list, we;

  • Talked with our customers to see which products they use and like
  • Used our own experience of using these products
  • Talked with local cat fosterers to get their input
  • Looked at reviews on websites like Pets at Home and Amazon to get the thoughts of other users

This gave us 16 products to test.

How We Tested

We ran our tests after running our tests to find the best cat litter.

Once that test was over, we asked those customers to then test our chosen litter fresheners.

Every day for 6 weeks, scooped those litter trays twice a day. We scored the products on two factors;

  1. Price
  2. Odour control, and
  3. Whether our test cats were happy to use their litter trays

After testing 16 different types of litter fresheners over 6 weeks (and continually), we picked 4 of the best.

Moodify Pet: The Best Cat Litter Odour Eliminator

Moodify Pet Review
Cost3.5 out of 5.0 stars
Effectiveness4.4 out of 5.0 stars
Happy Cats5.0 out of 5.0 stars
Total Score4.4 out of 5.0 stars (4.3)

Moodify Pet is the best cat litter eliminator. Unlike the other products in this list, you don’t put it into the litter tray. Instead, it’s a clay pendant that you hang above the litter tray at nose height.

The big benefit is that you won’t put your cat off using their litter box.

Moodify Pet isn’t a freshener or deodorizer, but an odour blocker. 

It uses what’s called ‘white scent technology’. It works by blending different scents to create a ‘smell-cancelling‘ effect. It’s the smell equivalent to the noise-cancelling technology in your headphones.

It sounds like a gimmick, we know. But it’s surprisingly effective!

The cheapest way to pay for Moodify Pet is to sign up to their subscription which costs £9.90 per month. That said, making a single order each month is almost twice the price. Also, this cost can add up if you have more than one litter box.

That said, if you only have one cat, we think £9.90 a month is a fair price.

Rocco & Roxie Litter Box Odour Eliminator: Best For Multi-Cat Households

Rocco & Roxie Cat Litter Odor Eliminator
Cost4.0 out of 5.0 stars
Effectiveness4.0 out of 5.0 stars
Happy Cats4.5 out of 5.0 stars
Total Score4.1 out of 5.0 stars (4.1)

Rocco & Roxie Litter odour Eliminator is an excellent product and well-reviewed by users.

We have to say, we were quite sceptical when we first opened the container. The smell was pretty strong and we thought it would put many cats off using their litter boxes. That said, it does calm down once it’s in the litter tray. Plus, we’ve tested this with a few cats and they all seem happy.

This litter freshener uses a blend of essential oils. The manufacturer says they, ‘neutralize odours at the molecular level’

All sounds very scientific!

What we do know is that the instructions say to use 2-3 tablespoons but we’ve found it works with half that. This is good news because a bottle lasts for ages.

You can also use it to freshen up the smell in cat litter bins too.

It is pretty expensive compared to other products in this list. That said, it’s well-reviewed by lots of users and it last longer than expected. So, it does offer good value.

Simple Solution Cat Litter Freshener: A Good Cheap Option

Simple Solution Cat Litter Deodorizer
Cost4.5 out of 5.0 stars
Effectiveness4.0 out of 5.0 stars
Happy Cats3.5 out of 5.0 stars
Total Score4.0 out of 5.0 stars (4.0)

If you’re on a budget, Simple Solution Cat Litter Freshener is excellent.

For starters, it’s very well-priced.

It has a scent which they call ‘Spring Breeze’ but it’s not overpowering. As such all our test cats were happy to use their litter trays.

It also does a good job of neutralizing stinks rather than trying to cover the up with a different smell.

The manufacturer also says it has ‘Pro-Bacteria’ that’s activated when your cat users their litter box. We have no idea what this means, but we found that the product did a good job controlling odours.

That said, we didn’t find it to be very long-lasting. It worked, but we had to use it often.

For the price though, it’s very good.

How to Choose the Best Cat Litter Deodorizer For You and Your Cat

When choosing a cat litter deodorizer or odour blocker, there are a few things to consider;

How Many Cats You Own

If you have;

  1. More than one cat, and
  2. Litter boxes around the house 

The cost of using odour blockers like Moodify Pet could add up. In this case, it’ll be more cost-effective to use a traditional powder or granular product. 

Also, more cats often mean more stink, especially if your cats share a litter box. In this case, you might be better off spending a little more to get better odour control.

Your Cat’s Sensitivities

While cat litter freshers help us to put up with the stink, they’re not always good for our cats.

As we mentioned earlier, many cats don’t like strong perfumes. If that’s your cat, then an ‘outside of the litter box’ odour blocker like Moodify Pet is a better choice.

Litter Box Location

One of the cheapest ways to deal with it is to move it to a different part of the house. A place away from high-traffic areas of the house.

This might not always be possible, especially if you live in an apartment or small house. This might mean a cat litter freshener might be a must.

In Conclusion

One of the biggest complaints we hear about cat ownership is the smell of their litter boxes.

Regular scooping and cleaning will help. That said, using a litter freshener, deodorizer or odour blocker will definitely improve things.
