What is Biodegradable Litter?


For cat owners, litter is an essential part of their daily routine, but few people think about the long-term impact of traditional clay or silica litters. Biodegradable litter presents an eco-friendly alternative made from natural materials such as corn, wheat, pine, paper, or walnut shells. These materials break down more easily in the environment compared to conventional litters.

Benefits of Using Biodegradable Litter

Biodegradable litter offers many advantages that go beyond environmental sustainability. Here are some notable benefits:

  • Eco-Friendly: Biodegradable litter decomposes more quickly than traditional litter, reducing landfill waste.
  • Safer for Pets: Natural materials are often less toxic and may lead to improved health for your pet.
  • Lower Dust Levels: Many biodegradable options produce less dust, which is beneficial for both humans and pets, especially those with respiratory issues.
  • Odor Control: Some biodegradable litters offer excellent odor control due to natural absorbing properties.
  • Lightweight: Often lighter than conventional litter, making it easier to handle and transport.
  • Sustainable Sourcing: Many biodegradable litters are made from renewable resources, contributing to a lower carbon footprint.

Types of Biodegradable Litter

Let’s explore the various types of biodegradable litter available:

Corn-Based Litter

Corn-based litter uses processed corn kernels or corn cobs. This type is advantageous due to its strong clumping capability and excellent odor control. It’s also safe if ingested by pets, which is great for curious kittens.

Wheat-Based Litter

Made from ground wheat or wheat by-products, wheat-based litter can form tight clumps and control odors effectively. It’s often flushable, adding convenience to its list of benefits.

Pine Litter

Pine litter is made from pine wood shavings or pellets. It offers natural odor control and has a pleasant woody scent. Pine litter is very absorbent and significantly reduces dust, making it ideal for sensitive pets.

Paper-Based Litter

Recycled paper is the main ingredient in paper-based litter. This type is usually in pellet form and is soft on your pet’s paws. It absorbs moisture well, though it might not clump as effectively as other types.

Walnut Shell Litter

The fibrous shells of walnuts can be turned into highly absorbent and odor-neutralizing litter. Walnut shell litter is usually dark in color, which can help hide waste better.

Comparing Biodegradable and Traditional Litters

When considering whether biodegradable litter is worth it, it’s handy to compare it directly with traditional options:

Environmental Impact

Traditional litters are low-biodegradability and can take years to decompose. Biodegradable options break down more naturally and quicker, reducing landfill waste.


Biodegradable litters may be more expensive upfront compared to traditional clay litters. Nevertheless, the long-term environmental and health benefits might justify the cost.


Biodegradable litters generally offer good odor and moisture control, but this can vary depending on the type. Traditional clay and silica litters have a proven track record, although they often come with dust and health concerns.

Health Factors

Biodegradable litters are made from natural materials, reducing the risk of chemical exposure. Traditional litters can contain silica dust, which can be harmful to both pets and humans.

How to Make the Switch

Switching to biodegradable litter can be smooth for both you and your pet. Here is a simple guide:

Gradual Transition

To avoid stressing your cat, mix your current litter with the new biodegradable one, gradually increasing the amount of the new litter until it fully replaces the old.

Observe Your Pet

Watch how your cat reacts to the new litter. Some cats can be picky, so it’s essential to monitor their usage and make adjustments if necessary.

Adjust Cleaning Routine

Biodegradable litters may require more frequent changing or scooping. Adjust your cleaning schedule to maintain hygiene and prevent odor build-up.

Know Your Disposal Options

Check if the biodegradable litter you’re using is flushable or compostable. Follow the manufacturer’s guidelines for disposal to maximize environmental benefits.

Addressing Common Concerns

Some pet owners have reservations about switching to biodegradable litter; it’s natural to want to address these concerns:

Odor Control

People often worry whether biodegradable litter can manage odors effectively. Many biodegradable options use natural odor-absorbing properties to combat unpleasant smells.

Clumping Ability

While some biodegradable litters might not clump as well as clay options, there’s a variety that excels at clumping. Testing different brands will help you find the best one for your needs.

Availability and Cost

Biodegradable litters may not be as widely available as conventional ones, and they can be more expensive. Looking for sales or buying in bulk can help mitigate the cost.

Case Studies and Reviews

Understanding the real-world performance of a product can help solidify the decision to switch. Many users share their experiences online, offering valuable insights:

Corn-Based Litter Review

Reviews often highlight the strong clumping and excellent odor control of corn-based litters. Users frequently mention the safety of the product if ingested by pets.

Wheat-Based Litter Review

Wheat-based litters get high marks for being flushable and forming tight clumps. Users appreciate the additional convenience this offers.

Pine Litter Review

Pine litter users compliment its natural scent and excellent absorbency. However, they note that it may require frequent changes to maintain freshness.

Paper-Based Litter Review

People who choose paper-based litter often do so for its softness and low dust. Reviews indicate it’s most suitable for pets with sensitive paws or respiratory issues.

Walnut Shell Litter Review

Walnut shell litter reviews praise its superior odor control and high absorbency. Some users, however, find the darker color makes it challenging to see waste spots.

Frequently Asked Questions

Is Biodegradable Litter Safe for Cats?

Yes, biodegradable litter is generally safe. They are made from natural, non-toxic materials, reducing the risk of chemical exposure. Always read product labels and consult your vet for any concerns.

How Often Should I Change Biodegradable Litter?

This depends on the type of litter and frequency of use. Pine or paper-based litters may need changing more often than clumping varieties like those made from corn or wheat. A regular scooping routine helps extend the life of the litter.

Can I Compost Used Biodegradable Litter?

Some biodegradable litters are compostable, but make sure the product label confirms this. Avoid using compost from pet waste on edible gardens to prevent the risk of spreading pathogens.

Finishing Thoughts

Biodegradable litter offers a compelling alternative to traditional clay and silica-based products. With their reduced environmental impact, increased safety, and multiple types to choose from, they present numerous benefits for conscious pet owners. Although there might be some adjustments required, such as cost and availability, the long-term benefits make biodegradable litter a worthy consideration for your cat’s needs. Always transition gradually and observe your pet’s behavior to ensure a smooth switch. Happy pet parenting!
