What About Cat Litter?

According to the American Pet Products Association’s 2019-2020 National Pet Owners Survey, there are approximately 43 million homes in the U.S. with cats. Count me in that group with seven cats living at our home. The best ways to remove pet odor from home pose a constant challenge for us.

So, what about cat litter? We use it in our litter boxes without much thought to provide a sanitary way for cats to relieve themselves indoors and control the odors caused by cat urine and feces. How does it work? Is it safe for humans and animals? What types of cat litter are available? Are there alternatives to cat litter? Continue reading if you’re curious about cat litter and its role in keeping our homes a healthy and odor free place to co-exist with our felines.

Where It all Began

Cat litter traditionally consisted of using absorbent materials like paper, sand, dirt, or other available absorbent materials. In 1947, an Englishman named Edward Lowe worked in his father’s company which created industrial absorbents. One such product was a clay like substance called Fuller’s Earth. Edward Lowe eventually began to market this product under the name of ‘Kitty Litter’ using Sodium Bentonite clay as its key ingredient.

Throughout the years, this product has been refined and other cat litter products with similar functionality have been created. This cat litter is very popular due to its clumping action which absorbs the moisture and odors from cat urine and feces. The clumps are easily removed and replaced with fresh litter.

How does Cat Litter Remove Odors?

Cat litter depends on its primary ability to absorb moisture from urine and feces. This alone will cut down on odors. Cat litter is developed to simplify litter box maintenance and odor control. Different materials are used to control odors and provide a clean litter box.

  • Clay – Highly absorbent clays are used in some litter to absorb moisture and bind the odors. These litters are either Clumping or Non-Clumping. Each type has their distinct advantages. The clumping type litter uses Sodium Bentonite which absorbs moisture and odors and forms an easily removable clump. The non-clumping type uses Calcium Bentonite clay.
  • Crystals – Silica gel particles are the active ingredient in this type of litter. The particles contain spongelike pores that absorb moisture and the odors from cat urine and feces. This cat litter controls odors longer than clay types but will eventually lose its effectiveness when the crystals become too saturated with moisture.
  • Natural Materials – Unlike clay and crystal cat litter, litter made from these materials depends on their natural abilities to absorb moisture and odors from cat urine and feces. Their biggest advantage may be that they’re biodegradable and environmentally friendly.

Types of Cat Litter

There are many things to consider when choosing a cat litter. In this case, one size does not fit all!

Scented or unscented? While masking the odors with a strong pleasant scent, most cats don’t like the strong scent which linger on the cat’s fur after using the litter box.

Multiple cats? You should consider using a litter that is easy to maintain, long lasting, and affordable. This situation typically calls for the use of multiple litter boxes for the best odor control.

Some litter produces more dust than others. If you or your cat has asthma, it’s probably best to avoid using these types.

Here’s a brief rundown of types available. Experimentation may be necessary to find the best litter for you and your cat. Check with your veterinarian about the safest type for your cat if your cat suffers from food allergies or asthma.

  • Clay – This litter is the most popular, especially the clumping type. This type tends to be dusty and more expensive than non-clumping types. Litter box maintenance is easier, but clay types are not biodegradable and your cat may not like using the litter box containing this type of litter.
  • Crystals – This type can control odors better and longer than clay types, but they are non-clumping. Crystals are typically more expensive than clay types. These types can be dangerous to cats licking their paws and ingesting too many crystals. More current formulations have made safer products available.
  • Eco Friendly – This litter is made from materials found in nature. Before clay litter was invented, this was the cat litter that was used. They usually don’t clump, they’re mostly low or dust free, and they’re biodegradable.


Eco-Friendly materials like Corn, Grass, Green tea, Walnut shells, Wheat, Sand, Recycled newspaper, Wood shavings, Sawdust, and Wood pellets are some materials used. Corn and walnut shells clump well but cleanliness due to tracking around the litter box is an issue with many of these. Wood pellets smell nice, but their size is bigger than the holes and slots in regular scoops making litter box maintenance a bigger chore.

I have used wood pellets in the past, but switched back to clay litter for that reason. A lot of people that use them report that they tend to be dusty. That was my experience too.

Alternatives to Cat Litter

For those that want to take a trip off the beaten path towards cleanliness and odor control for your cat, here are some unconventional methods. These methods could be a suitable option for cats who are unable to use a regular litter box, the ambitious do-it-yourselfer, and for the frugal homemaker.

  • Paper Litter – Recycled paper is plentiful and cheap. Some pet companies sell recycled and formulated recycled paper as cat litter. Paper has a pleasant odor and is biodegradable and compostable.
  • Wood Shavings – If you have a woodworking shop at home, saving the sawdust or wood shavings makes great natural litter. Hardwoods like Aspen and heat-treated wood shavings can make suitable litter, safe for cats.
  • DYI – There are numerous recipes available for homemade cat litter that control odors. Concoctions containing materials like: Dish Soap, Water, Shredded Paper, Baking Soda, and other materials can be a very cost effective option.
  • Diapers – Cat diapers are a good option for cats with incontinence or paralysis. You can find them online. These diapers are reusable.
  • Human Toilet Training – This can be done if you can train your cat to use the toilet. There are special support systems available for the cat to facilitate using the toilet. I bet cleanup and odor control would be a breeze if you were successful in training your cat this way.
  • Odor Eliminators – These are products that neutralize litter box odors. They work along with cat litter to help extend the life of cat litter. Just remember that while providing an odor free litter box for a little while longer, these products are not a substitute for good litter box hygiene.

So That’s What It’s About

    We personally use wood pellet cat litter in our home. I find it cheaper than the alternatives on the market, including the so-called expensive eco-friendly versions. It also absorbs the odour very well. As long you replace it regularly then you will not suffer from bad smells etc.

    But to be fair, cat litter should be replaced reasonably regular as the cats tend not to want to do their business in an unclean litter box. We do tend to remove the dirty litter and re-use litter that hasn’t been disturbed in an attempt to cut waste also.

      Hi Lawrence, Our experience with wood pellets was a short one. My wife brought a new cat into the house. The previous owner brought the cat up using wood pellets. With seven cats and four litter boxes, our maintenance was practically a full time job to keep the smell down. The wood pellets just didn’t work out for us. Fortunately, the new cat took to the clumping litter we were using before. Small miracles do happen.

      Thanks for writing back. Lawrence,

    I was using natural wood pellets for cat litter. Had to change it as my kitty is overpreening, maybe the litter. Doubt it she still does it a while after I changed to Catsan.

    1. Bob says:

      Hi Alan, We used the wood pellets for a short while but we switched back to the clumping litter. Litter box maintenance was almost a full time job with seven cats! I can understand that the wood pellets may contain something that is causing over preening. Hopefully the Catsan litter will do the trick for you.

      Good luck with that, Alan and thanks a lot for writing back,

    Thank you for your post. My sister has 5 cats and my Mom complains to her cats litter odors every single day. She uses sand. Sand doesn’t help to control the odor. I think I’ll suggest her to try your ideas using wood pellets or recycled papers. Hope these would work better than sand.

    1. Bob says:

      Hi Ferra,

      Thanks for writing!

      Five cats can generate a lot of litter odor! Clumping litter seems to be the best as far as odor control. I’m assuming your sister has multiple litterboxes in different places in the home. If not, that would be a really good start. Sand litter doesn’t clump, so close attention should be paid to regular scooping.

      The wood pellets or newspaper litters are kind to the earth and will work out well if her cats will like using it. Keeping up on cleaning the litterboxes with these types are important for odor control.

      If her cats are used to sand and won’t use anything else, have her try some baking soda in the litterboxes. Baking Soda absorbs odors. You may have heard about putting an open box of baking soda in a refrigerator to control odors inside. It works the same way with litterboxes and other odor control issues around the home.

      Hopefully these ideas will help keep you mom, your sister and her cats content in an odor free home.

      Good luck with that,
