Is Cat Litter Compostable?

Imagine the mountain of cat litter your pet might produce in a year – have you ever wondered if there’s an eco-friendly alternative to simply tossing it out? It may surprise you to learn that certain types of cat litter can, indeed, be composted.

This blog will guide you through understanding which types are suitable for composting and how this process works. So get ready, we are about to dig deep into the world of compostable cat litter!

Types of Cat Litter

There are several types of cat litter available, including clay litter, sand-based litter, crystal litter, and biodegradable and compostable litter.

Clay Litter

Clay litter, commonly used because of its affordability and convenience, is made from strip-mined clay. This type presents several environmental concerns as strip mining is damaging to the ecosystem, contributing heavily to erosion and habitat destruction.

Also inherent in clay litter are synthetic toxins, which can be harmful if ingested by pets or released into the environment upon disposal. Unlike some other types of cat litters such as those made from biodegradable materials like crushed walnut shells or wood pellets, clay litter should never find its way into your compost bin.

The reasons for this are two-fold: firstly, it doesn’t decompose over time; secondly, harmful bacteria present in cat waste might end up contaminating your compost pile when using non-compostable litters like clay-based ones.

While many pet owners appreciate the clumping properties and odor control offered by a traditional clay litter, these benefits do not outweigh the environmental costs associated with using this type of product.

Sand-based litter

Sand-based litter is a common type of cat litter that is made from sand or silica gel crystals. It provides good odor control and absorbs moisture well. However, sand-based litter may not be compostable due to its inorganic nature.

Unlike biodegradable plant-based litters, sand-based litter does not break down naturally and can have negative environmental impacts if disposed of incorrectly. Therefore, it’s important to choose an alternative compostable option if you are looking to reduce waste and have a more eco-friendly approach to managing your cat’s litter box.

Crystal litter

Crystal litter, also known as silica gel litter, is a type of cat litter made from synthetic crystals. These crystals are designed to absorb and contain moisture and odor effectively.

While crystal litter is not compostable, it can still be an eco-friendly option because it lasts longer than other types of litters, reducing waste in the long run. Additionally, crystal litter requires less frequent changing and produces less dust compared to clay or sand-based litters.

However, it’s important to note that some cats may have preferences for different textures or scents when using their litter box.

Biodegradable and compostable litter

Biodegradable and compostable cat litter is an eco-friendly option for pet owners who want to minimize their environmental impact. This type of litter is made from plant-based materials like grains, paper, or wood pellets, which can break down naturally over time.

Unlike clay-based or chemically clumping litters, biodegradable and compostable litter can be safely added to a compost pile or green bin designated for organic waste. It’s important to note that not all biodegradable litters are suitable for composting, so check the packaging or contact the manufacturer for specific instructions.

By choosing biodegradable and compostable litter, you can reduce your carbon footprint and contribute to a more sustainable approach to pet care.

So, to answer your question of Can Cat Litter be Composted?

Yes, certain types of cat litter can be composted, but it requires careful consideration and proper composting methods. To learn more about what types of cat litter are suitable for composting and how to properly compost it, continue reading.

Composting considerations

To compost cat litter, there are a few important factors to consider. First, it’s crucial to use the right type of cat litter. Biodegradable and plant-based litters made from grains, paper, or wood pellets are generally safe for composting.

However, clay-based litters, sand-based litters, scented litters, and those that contain synthetic toxins should not be composted due to their potential negative effects on the soil.

Another consideration is the proper method of composting. It’s recommended to separate the cat waste from the litter before adding it to your compost bin or pile. This can be done by using a scoop or sifting through the litter material.

Additionally, make sure you’re following proper composting practices such as maintaining correct moisture levels and turning the pile regularly.

Suitable types of cat litter for composting

Plant-based cat litters made from grains, paper, or wood pellets are suitable for composting. These types of cat litter are biodegradable and break down naturally over time, making them safe to add to your compost pile.

However, it is important to note that clay-based litters, sand-based litters, scented litters, and chemically clumping litters should not be used for composting as they can contain synthetic toxins that can harm your soil and plants.

Stick to eco-friendly options like crushed walnut shells or biodegradable cat litter brands that specifically state they are safe for composting. Remember to only use the cat litter in your composter for composting purposes and not for other uses.

Proper composting methods

To properly compost cat litter, it is essential to follow a few key steps. First, make sure you have a designated composting area separate from your regular garden compost. Next, choose a biodegradable cat litter made from plant-based materials like grains, paper, or wood pellets.

Avoid clay-based or chemically clumping litters as they are not suitable for composting. Scoop the used litter into a separate container and mix it with other organic matter like grass clippings or leaves in your designated compost area.

Turn the pile regularly to ensure proper decomposition and break down any potential bacteria or toxins. Remember to only use this compost for non-edible plants due to the risk of pathogens that may be present in cat waste.

Benefits and Risks of Composting Cat Litter

Composting cat litter offers several benefits, such as reducing waste sent to landfills and creating nutrient-rich soil for gardening. However, there are risks to consider, including the potential spread of pathogens and parasites if not composted properly.

Benefits of composting cat litter

Composting cat litter offers several benefits for both the environment and your garden. First, it helps reduce waste by recycling your cat’s litter instead of sending it to landfills.

By composting, you are minimizing the amount of waste that ends up in already overflowing landfills. Additionally, composting cat litter can help improve soil quality as a natural fertilizer.

The nutrients released from the decomposed litter can enrich the soil and promote healthy plant growth in your garden. Furthermore, composting is an eco-friendly way to dispose of pet waste while reducing the use of plastic bags and other non-biodegradable materials.

Risks and precautions to consider

Composting cat litter can come with risks and precautions to consider. One important factor is the type of litter being used. Clay-based, sand, scented, or chemically clumping cat litters should not be composted as they may contain synthetic toxins that are harmful to the environment.

Additionally, it’s crucial to recognize that any cat litter thrown in the compost bin should be used for composting purposes only and not mixed with food waste. Clumping cat litter may also pose challenges in fully breaking down during the composting process.

Considering these factors will help ensure safe and effective composting of cat litter while minimizing potential risks.


Yes, cat litter can be compostable, but it depends on the type of litter used. Plant-based cat litter made from grains, paper, or wood pellets is typically compostable. However, clay-based or chemically clumping litters should not be composted as they may contain synthetic toxins.

Proper composting methods should also be followed to ensure safe decomposition of the litter. Ultimately, choosing a biodegradable and compostable cat litter option can help reduce environmental impact and promote sustainability in pet care practices.
