How to Control Bad Odor?

If you think that the stench of urine and poop is something that you have to live with, think again!

Although it’s not realistic to get rid of bad odor completely, there are several things you can do to improve the situation quite a bit:

  1. Food. By providing your cat with quality food (e.g. food containing less grains and starches), the excrements will smell better.
  2. Litter. Buy the best cat litter for odor control, and fill the litter box with at least 2-3 inches of it.
  3. Cleanliness. Scoop and clean the litter box at least two times a day, and change all the litter and clean the box thoroughly with hot water once a week. Consider getting a self-cleaning litter box.
  4. Location. Place the litter box in a well-ventilated room.
  5. Odor control products. There are various products (deoderizers, eliminators, air purifiers, etc.) that could be used to reduce or mask bad odor.

Why Does Cat Urine Smell So Bad?

Cat urine smells bad, mainly because:

  • It contains urea. Bacteria breaks down urea to ammonia, which is a very smelly substance.
  • Cat urine is more concentrated than in most other animals.
  • It contains pheromones, which the cat uses for marking its territory.

Other reasons can be diet, gender, age, level of certain hormones, and genetics.

Types of Cat Litter

If you’re about to get your first cat, choosing a cat litter can be really confusing, because there are so many different types to choose from.

The most commonly used materials are:

  • Silica gel crystals
  • Clumping bentonite clay
  • Non-clumping clay
  • Grass
  • Pine
  • Recycled paper pellets
  • Corn
  • Ground walnut shells
  • Wheat

Which one should you use? Well, the perfect cat litter should absorb odor, be dust-free, affordable, and safe to ingest. Unfortunately, it’s hard to find a single product that ticks all the boxes.

But if we focus on minimizing bad odor, I would recommend that you go with a product based on one of four materials: silica gel crystals, clumping bentonite clay, recycled paper pellets, or ground walnut shells.

In order to dig deeper, I’ve picked out and reviewed the best product made of each of those four materials (and from only the most reputable brands). Scroll down to read the reviews, or check out the table at the top of the article.

Cat Litter Reviews

The first things you need to do is ask yourself, should I choose a scented or an unscented litter?

Generally, cats don’t like scented litters and may even poop outside the box because of it. Keeping things as natural as possible is often the best way to go when dealing with pets.

That’s why I recommend that you use an unscented litter.

And that’s also why all four litters reviewed are unscented.

So Phresh Odor-Lock Crystals Review

So Phresh Odor-Lock Crystals is the highest rated silica gel crystal cat litter on Amazon.

This product from So Phresh is a great choice if you want a low-maintenance product.

The non-toxic silica crystals absorbs urine, and dehydrates poop, for up to a month before you have to clean the box and replace the old litter with fresh litter. Bad odor is locked inside the crystals so that you only have to scoop up the poop. It’s a real time saver!

Even though it costs more per package, this cat litter is not as expensive as it might seem, because it lasts longer than conventional clumping clay litter.

  • Highly absorbent
  • Almost dust-free
  • Unscented
  • Low maintenance – can absorb liquid and odor for up to one month
  • Expensive


Ever Clean Extra Strength Cat Litter Review

The unscented version of Ever Clean Extra Strength Cat Litter is an extremely popular product, and it has earned a 4.5 rating on Amazon. Impressive!


Ever Clean has several different litters on the market that all work well, but this bentonite clay has been designed to clump extra strongly, and that feature really makes a difference. It’s very easy to clean up after your cat.

It’s also great at stopping bad odor as it contains both activated carbon that eliminates bad smell, and an antimicrobial agent that stops smelly bacteria from growing.

Given its relatively low price, I can highly recommend this product.

  • Affordable
  • Great odor control
  • Easy cleanup
  • Unscented
  • Relatively dusty


Purina Yesterday’s News Paper Pellet Litter Review

Purina Yesterday’s News Original Paper Pellet Unscented Cat Litter is the absolute best cat litter made from recycled paper.

By using pellets made from recycled paper, Purina has created a very popular cat litter that’s highly absorbent, soft, and almost dust-free.

Veterinarians recommend it, and so do I.

The only concern I have is that because it’s non-clumping, you need to scoop and change litter regularly. But if you’re OK with that, go ahead and buy it!

  • Unscented
  • Low dust
  • 3x more absorbent than clay
  • Gentle on sensitive paws
  • Needs regular scooping


BLUE Naturally Fresh Ultra Odor Control Cat Litter Review

BLUE Naturally Fresh Ultra Odor Control is an unconventional cat litter as it’s made from ground walnut shells.

If you want a completely natural cat litter, this product from BLUE should be your top choice.

It’s unscented, doesn’t contain any chemicals or clay, and it doesn’t harm the environment. And it lasts longer and has 3x better absorption than the best clay litter. Great if you have multiple cats.

The manufacturer actually claims that one bag of it is equal to three bags of regular clumping clay litter.

My only concern is that ground walnut shells is not as tried and tested as the other materials. It has received mixed reviews, although most of the customers have given it fantastic reviews.

It’s definitely worth a try!

  • Unscented
  • 100% natural
  • Environmentally friendly
  • Highly absorbent
  • Almost dust-free
  • Unconventional material
