Best Biodegradable Cat Litter

Whether you have an indoor or indoor-outdoor cat, cat litter is a must. If you are environmentally concerned about the impact and toxicity of the cat litter you’re buying, switching to a biodegradable cat litter is a step in the right direction. Many clay litters are derived from earth damaging processes like strip mining. Whereas, biodegradable cat litter comes from plant sources such as wheat, pine, corn, and recycled paper. You can find both non-clumping and clumping varieties with a range of odor control. Some brands are compostable as well but it is not recommended for your fruit and vegetable garden.

What is Biodegradable Litter?

In general, biodegradable cat litter is:

  • ​Eco-friendly
  • Flushable
  • Low in dust
  • Non toxic
  • Leaves no crumbs or trails throughout your house
  • Slightly more expensive than traditional litter (but you’re getting quality)

Biodegradable cat litters are plant-based, so they should decompose naturally. Biodegradable litter can be made from grasses, walnut shells, corn, wheat, pine and paper. Many of the biodegradable options available have low dust levels and control odors well. One thing to consider when looking into biodegradable litters is the source of the material used. Whether the product is the remnant by-products of another industry or produced specifically for cat litter is another factor to think about. Some cat owners prefer to buy cat litter that isn’t made from potential food sources for humans like corn and wheat. Price is another big factor when it comes to biodegradable litter, as most biodegradable litter is considerably more expensive than clay or silica litter.

What to Consider When Choosing a Biodegradable Cat Litter

Odor Control – Keeping the smell of cat box odors under control is at the top of any cat owner’s wish list. Artificially scented litters aren’t a good solution, as cats often reject litters with strong scents.

Low Dust – Clumping clay litter can produce a lot of dust, which is an irritant for both cats and their humans. Dust can create a mess around the house and on the paws. Natural litters usually produce little or no dust.

Granule Size – Cats tend to prefer a fine textured litter because it’s softer on their paws. A more coarse litter is less likely to get tracked around the house. Kittens under three months old are better off using coarse litter, so that they do not inhale or swallow it.

Good Clumping – Clumping litters usually control odor better than non-clumping ones. Clumping litters also require less work, since scooping a litter box daily is easier than dumping out and replacing the contents every week.

Reasonable Cost – Clumping clay litters are more popular because they are usually much cheaper than other types. A cheap litter that you have to change every week can end up costing you more in the long run than a pricier litter that keeps working for a longer period.

Is Clay Cat Litter Bad?

There is some concern about clay cat litter among cat owners. Although it hasn’t been fully documented, some people and a few veterinarians say that pets have died from ingesting or inhaling the clay or clay dust while using the clay cat litter. There have been some studies done on the subject but nothing conclusive has been found. The concern is that when clay dust is inhaled it may harden when by the lungs and cause multiple breathing problems such as allergies, bronchitis, pneumonia, to name a few. The same concern has been expressed about the humans who clean the cat litter.


Biodegradable cat litter is a much healthier and eco-friendly option over conventional clay litter. The biggest benefit is that they can be recycled or composted and will not end up in landfills for years.
