Choose biodegradable kitty litter

Choose biodegradable kitty litter because it decomposes faster than clay-based litters whether you compost it or send it the way of the landfill. It also won't tax the environment with harmful strip mining production processes.

Find it! Biodegradable kitty litter

Before you buy

Some of the litters specify that their products are made from post-consumer waste or reclaimed products. For others, it's unclear whether they are manufactured with byproducts. The main differences between kitty litter alternatives have to do with clumping ability and odor absorption. Some cats can exhibit feline fussiness when it comes to litter, but many companies include tips on how to "acclimate" your cat to the change. You might have to engage in some trial and error before you reach a happy medium for both you and Fluffy.

Choosing biodegradable kitty litter helps you go green because...

  • It will not accumulate in landfills taking decades to decompose, like clay-based litters do.
  • It is not unsustainably strip mined, which takes a heavy toll on the environment.

In the United States alone, there are approximately 88.3 million cats kept as pets in households across the country.[1] As a result, more than 2 million tons of kitty litter is dumped in landfills each year, the weight of five Empire State Buildings.[2]

Clay-based litter is usually made of bentonite or attapulgite/montmorillonite which is mined in unsustainable ways. This litter is also known to contain silica dust. Although it has not been shown to directly cause problems in cats, studies have found that cats with respiratory illnesses have six times the amount of silica in their lungs than do healthy cats.[3] Alternative kitty litters that are more eco-friendly and contain biodegradable ingredients, such as corn cobs or wheat, eliminate this health risk, as well as lighten the burden clay-based litters have on landfills. People with wheat allergies should avoid wheat-based litters due to the possibility of an allergic reaction.


  • silica: Found in common minerals like quartz, sand, and agate, this substance is naturally occurring, ubiquitous, and chemically unreactive in the environment.
