Best Unscented Cat Litter (Reviews)

If you have a cat, you know how sweet and endearing they can be. And who doesn’t love a great cat video?

It is estimated that there are well over 2,000,000 cat videos available on the internet.

There was even an urban legend a few years ago that cat videos represented 15% of the internet… just imagine if that were true?

And let us not forget adorable and grouch-faced Grumpy Cat, who sadly passed away in May 2019 from complication tied to a urinary tract infection.

People love their cats.

And while people love their cats, they definitely don’t love the clean-up that comes with cat (or other pet) ownership.

But really, there is nothing you can do to avoid the clean-up, though you can absolutely make it the least unpleasant experience possible.

And since you’ll be buying a lot of cat litter over the expected lifespan of your cat (sometimes as much as 16 years or more), you’ll likely go through 20 pounds of cat litter every 12 – 16 weeks.

With multiple cats, and especially if each cat has his own litter box (and since in most sized litter boxes, you will need to put down three pounds to cover the base), you can assume that you’ll be buying cat litter much more frequently.

World's Best Cat Litter Clumping Formula  

Cats truly do care about texture, and we know that they like to dig in their litter boxes before doing their you-know-what.

This corn-based clumping formula by World’s Best Cat Litter not only takes into account that texture preference, but also makes clean up easy.

Finally, and perhaps most importantly, this biodegradable 99% dust-free product is environmentally friendly and is completely safe for both septic and sewer systems, which means you can use your toilet to simply flush it away.

For this product, the manufacturer recommends that it only be used in homes with one or two cats, as the odor capture feature is not as effective with more.

  • Safe for flushing in septic and sewer systems


  • Higher risk of tracking
  • Not suitable for homes with more than two cats

Scented or Unscented cat litter: what is better?

What people don’t love about cat ownership is the scent of cat litter, which is quite the necessity for cat owners across the world. And just as annoying that stench is for you, your cat is also very particular about where they go about their private business.

If they don’t like the space you have provided, or the quality of the little you expect them to use, can you blame them if they decide to do their business in your favorite plant or pair of slippers?

Choosing an unscented or scented cat litter is really up to personal preference, both for you and your cat. As a cat owner, you may find that your cat prefers one or the other, but it is important to determine which option is better for you and others in your home as well.

In many cases, certain scents or the chemicals in cat litter that contribute to a scent, can trigger allergic reactions or other respiratory problems in people.

Not only that, some people can find that certain types of scents lead to skin infections including but not limited to eczema or dermatitis.

Veterinarians and cat lovers alike will tell you that unscented cat litter is the way to go.

As we hinted at before, cats can be put off by deodorized or perfumed surroundings. It is believed that a cat’s sense of smell is 14 times more attuned than what humans experience. And quite frankly, kitty litters are scented for us, and not for the cat.

So, you are really doing your cat a disservice by disrupting their environment with scents that they might not find all that inviting.

Often times as well, a cat litter manufacturer could be trying to hide unpleasant smells with the addition of fragrances.

When cat urine and cat litter mix, it often produces a foul ammonia-type smell, and to keep costs down, some companies try to hide the unpleasantness instead of looking for a solution that will solve the problem altogether.

Keep in mind though that you can never hide the smell of cat urine or feces, or kitty litter, permanently.

If you are using an odorless cat litter, make sure that you are not using too much or too little litter, that you clean out the box frequently, (at least two times per week) and that you do a full clean and sanitization at least once per month.

In general, most cat litters on the market offer some sort of odor control, even in an unscented option. And, many owners prefer to purchase scented litters to help cover up the smells of cat elimination.

Whatever you decide, there are a variety of options available in unscented or scented, for you to choose from.

what to look for when you buy The Best unscented Cat litter?

For most cat owners, they prioritize certain aspects of a cat litter over others. In the majority of cases, cat litter shoppers determine a preference for what they like, and then base their purchasing decision on the following:

Clumping Vs. Non-Clumping

Cat owners who choose non-clumping cat litter often believe that it has a better ability to absorb large volumes of liquid elimination, which in turn can aid in better odor control. Other buyers often look to non-clumping letter because the up-front price is lower.

Ultimately, clumping vs. non-clumping litter is truly a matter of personal preference and your cat’s reaction to the texture of the litter.


Not all litters are made the same. The most common formulas are made of one of the following:

  • Clay or Silica
  • Corn
  • Wheat
  • Pine
  • Grass Seed

ease in cleaning

Cat owners should properly clean them out at minimum twice a week when using a clumping formula.

Thankfully, clumping cat litters are designed for easy and quick clean-up. And as with anything you buy, this is often tied to personal preference, and again, not just for you, but for your cat.

And unfortunately, all allergies is different so it is impossible to indicate that any of these materials will keep you from scratching your eyes or suffering from allergic sneezes.

Unscented Litter Box Review Conclusion

Experts will tell you that the cat will have final say on the type of litter that he or she prefers, as ultimately, the cat is the king of the kingdom. 

But, owners have been well trained by their cats for generations, and generally believe that cats prefer smaller litter particles and odor-free litters. As cats originated as sand-walking felines, it is possible that those finer granules remind them of their home of centuries ago.

And as we already indicated, a cat’s sense of smell is 14 times more attuned than what humans experience, and as such, you will find them more likely to visit an unscented litter box than a scented one.

Mike Karg, Doctor of Veterinary Medicine, has gone on record to indicate that from his experience, cats prefer the following:

  • A large box, recommended to be 1.5 times the length of your cat from nose to tush
  • One box for each cat in the home. Just like your children want their own bedrooms, your cats want their own places to take care of business
  • Litter box in a quiet and private place – Humans don’t generally like to defecate in public, and neither do your cats
  • Accessibility – Your cat doesn’t like to hold it either, so ensure the litter box is available for use it all times
  • A clean litter box – Your cat will expect their humans to keep their box clean
  • The clump – Cats tend to like clumping litter because they can push their waste out of the way
  • Naturally-scented or unscented – Yet again, a cat’s sense of smell is 14 times more attuned than what humans experience, and as such, you will find them more likely to visit an unscented litter box than a scented one
  • No harsh cleaners – Cleaning products that use ammonia, bleach, or other harmful ingredients can be harmful to your furry friend
  • Inside another box or on top of a litter box mat – While this is less for your cat and more for you as the owner, a second box or mat can help keep those little granules from finding their way into your carpeting or the tiny crevices of your hardwood floor
  • Dust-free – Cats suffer from respiratory conditions too, so it can be better for everyone if the formula is low-dust or dust-free
