Is Clay Litter Bad for the Environment?

To put it simply, yes, clay litter is bad for the environment. Even worse, it could be bad for your health and the health of your cat!

Traditional litter is made of clay that’s obtained from strip mining. To strip mine the land, companies will raze entire forests to gain access to the clay underneath.

As you can imagine, this process is incredibly harmful to plant and animal life in the area. Plus, the pollution strip mining creates can spread for miles.

But environmental harm isn’t the only problem with clay litter. It can also contain hazardous substances like sodium bentonite and crystalline silica.

Sodium bentonite can be a respiratory irritant for cats and humans and is toxic if pets accidentally ingest it. Additionally, crystalline silica is a known carcinogen that has been linked to lung cancer.

Benefits of Natural Cat Litter

Natural cat litter has a lot of advantages over clay or silica gel cat litters. First, natural cat litter is healthier because it doesn’t contain artificial fragrances or chemicals that can cause allergic reactions in some cats and humans.

Additionally, natural litters are better for the environment because they’re biodegradable and they don’t leech chemicals into the soil. They’re also made from sustainable resources, such as quick-growing plants, upcycled food waste, and responsibly managed forests.

Plus, their natural scents and fibrous composition mean they’re just as good at minimizing odors as clay and silica gel litters. You’ll also appreciate that natural litters tend to have less dust.

If you have a kitty (or doggie!) who likes to sneak in the occasional snack from the litter box, a natural grain litter is safe for ingestion.

Now that you know why you should switch to natural cat litter and the benefits you’ll enjoy when you do, it’s time to take a look at the best natural cat litter for you and your feline family members.

Types of Natural Litters

There are four main types of natural cat litters: corn/grain, grass, walnut, and wood. Since they’re all made with a different natural product, they have different pros and cons you have to consider when you’re shopping for the one to suit the needs of your cat and your family.

Corn/Grain Litter

Corn/grain litter is made of compressed corn kernels that can sometimes be combined with other grains, such as wheat.

  • Pros: Made from grains, clumps well, produces very little dust, safe for ingestion, naturally minimizes odors
  • Cons: Can have a rough texture that some cats won’t like


Grass litters are made from the seeds of grasses like sorghum. Since they generate very little dust, they’re a good option for cats with respiratory problems.

  • Pros: Made from grass seeds, produces minimal dust, highly absorbent, naturally controls odors
  • Cons: Tracks easily outside of the litter box


Walnut litters are produced from the absorbent shells of walnuts. Once processed, the shells turn into a highly absorbent litter.

  • Pros: Made from walnut shells, produces minimal dust, tight clumping, highly absorbent
  • Cons: Easily tracks outside of the litter box, doesn’t control odors as well as other options, people with tree nut allergies shouldn’t use it


Wood litters are made from plant fibers that come from either sustainably sourced forests or reclaimed lumber. Their natural pine scent offers some of the best odor control of all the natural options.

  • Pros: Impressive natural odor control, produces minimal dust, sustainably sourced
  • Cons: Least successful at forming tight clumps

1. Best Overall: World’s Best Multiple Cat Unscented Litter

The company grinds the shells into a fibrous and naturally absorbent material that clumps together for quick and easy clean up. While the litter is fragrance free, it still offers natural odor control.
