Remember those episodes of Friends where Phoebe sings her song “Smelly Cat”? We laughed when we watched them, but some of the laughter comes from the nugget of truth found in the lyrics. Cats can be smelly—well, maybe not the cat exactly, but cat waste can be super smelly.

There was a commercial, a few years ago, for an air refreshing product that featured a guest arriving at the home and being surprised to find that there were cats in the house. The premise was that any house with cat residents would smell as if there were cats, or at least a litter box.

Both of these scenarios can be all too true. Cat urine has a very strong ammonia-like scent. It is distinctive. Very easily identified and not easily eliminated, the smell of cat pee can permeate your home. If you think the smell is bad, imagine how Kitty must feel.  Phew!

How Do You Keep From Having A “Smelly Cat”?

You shouldn’t have to do anything to keep your cat from smelling badly. Most cats clean themselves well, daily, and do so without any prompting from you. But, if you have an indoor cat, or two, you will want to take steps to keep your house smelling fresh and not like a litter box.

According to the ASPCA, more cat owners have multiple cats than dog owners have multiple dogs. Having more than one cat creates double the waste and can create double the smell. There are options for reducing the smell factor of being best friends with cats.

You can try using litter deodorizers. You can purchase scented deodorizing powder in a variety of scents. Be observant of your cat’s behavior if you use scented powders in the litter box. Some cats will stop using the box if they are strongly scented. You will want to choose a scent that is pleasing to you and your feline friend.

You can use baking soda, nature’s natural deodorizer, by sprinkling a little on the bottom of the litter box, before adding the litter. Baking soda rarely disturbs the sensitive noses of cats. It is also one of the most frequently found ingredients in odor control cat litter.

What Is Odor Control Cat Litter?

Odor control cat litter is designed to absorb or neutralize the odors that come with cat waste. Some litters use natural products, such as walnut shells and baking soda. Other odor control litters use chemicals like silica gel and “secret ingredients.”

The primary purpose of odor control litter is to keep the litter box from stinking up the area during the time between litter changes. It was for ease of cleaning the box that clumping litter was created. The cat’s waste is clumped together. The clumps make it easy to remove only the soiled litter, thus increasing the time between full litter changes.

No matter what kind of litter you use, the biggest prevention of cat box odors is cleaning. Constant, daily litter box cleaning is a requirement, especially in homes with more than one cat. Most professionals recommend changing the litter weekly (for clumping litter) or bi-weekly (for other litters), and giving the box a good wash while you have it empty.

Why Choose Odor Control Litter?

The primary reason for choosing odor control litter is to decrease the odors that emanate from the litter box. The secondary reason for choosing odor control litter is to increase the time you have between changing the litter.

The odor control litter will mask or absorb the smell from your kitty’s poo and pee, but will not eliminate the need for daily monitoring. Odor control litter, with daily removal of the dirty parts, will keep your home from smelling like a “Smelly Cat.”

To clarify, even with odor control litter, you should clean, or scoop, the litter box daily. Leaving a mess in the litter box will allow the urine and feces to sink to the bottom of the box, creating a larger—and stinkier—mess to clean later. So even with clumping and odor control litter, daily cleaning is a must.

Odor control cat litter is in high demand for homes with multiple cats. But which litter is best? Worry not, cat lover.

Tidy Cats 4-in-1 Strength Clumping Cat Litter

Tidy Cats 4-in-1 Strength Clumping Litter rates 4.5 out of five stars, with 318 reviews, on

Tidy Cats 4-in-1 addresses the four main concerns of cat litter users: urine, ammonia, feces, and messy clumps. The label claims that it neutralizes odors from urine and feces, as well as ammonia; that it locks in any moisture; that it forms strong clumps that don’t break up; and that it is 99.6% dust free.

The brand has been around for at least 50 years, recognizable by the bright yellow bucket. It is made from natural and chemical agents. The granules are supposed to both create solid clumps and eliminate odors.

Reviewers sing the praises of the litter’s odor control and clumping ability. The no odor aspect seems to please most of the users. One reviewer keeps the litter box in her bedroom closet but has not noticed any cat box smell in her room or her clothes.

Most of the reviews commented on the way this litter creates solid, not crumbly, clumps. They also appreciate the low amount of dust with this litter. Some reviewers complain of the odor of the litter itself.

Of course, no product is perfect.  The pros and cons list looks like this.


  • Cats seem to like it and adjust to it quickly
  • Superior odor control with regular cleaning
  • Clumping makes clean up easy


  • Strong chemical smell: while the label does say unscented, the manufacturer states that the ingredients used for odor control have a smell of their own
  • Clumps become like cement on bottom of pan
  • Cats track this litter outside the litter box

Overall the odor controlling factor of any of these brands seems to be dependent on the scent sensitivity of the user. One size—or brand in this case—will not fit all. You may have to sample a few before you find the perfect litter for your home and your fur family.

Remember, when trying new litters, to ease into them. Try mixing the new litter with the current litter for a few days. Then gradually increase the new litter until you have a full pan of the new. Some cats will become anxious if their litter is changed, so watch your kitty for signs of anxiety or rejection of the new brand.

Whichever brand you choose, remember to clean the litter pan daily to keep your home smelling pleasant and fresh.
