Are you an eco-conscious cat parent looking for a sustainable alternative to traditional litter?

If so, then you've come to the right place!

I'm cat obsessed and only want the best for my two American Shorthairs, Cleo and Pumpkin.

In this article, I'll channel my inner 'crazy cat lady' and deep dive (not literally! 🤢) and show you how I found the best eco-friendly cat litters available to cat owners in the US.

I'll also cover tips for making your litter choices greener (and even how you make your own), so read on if you want to ensure your kitty shares your eco-credentials.

Top 5 Eco-Friendly Cat Litters of 2024

Materials: Soybean Fiber, Corn Starch, Corn Flour, Guar Gum, Charcoal
Price: From $29 (9.50 lbs)
Ethics: Mindful ingredients, Cat education center
Shipping: Various locations worldwide

A reliable and efficient cat litter can make all the difference in keeping your home clean, hygienic, and smelling fresh.

Tuft & Paw Really Great Cat Litter is an absolute gem of a product that I (and Cleo and Pumpkin) love.

This natural clumping litter soaks moisture like a sponge, ensuring your kitty's bathroom stays dry and comfortable.

It also forms tight, easy-to-scoop clumps that make cleaning the litter box a breeze (and let's be honest, anything that makes scooping poop easier is a winner in my book).

But wait, there's more!

The charcoal-powered odor control in this environmentally friendly litter is nothing short of miraculous. No more worrying about your home smelling like a feline waste processing plant.

My darling Cleo and Pumpkin can be a tad fussy regarding litter. But they took to Tuft & Paw like ducks to water. I've also noticed their litter box habits have been more consistent since the switch.

Cleaning the litter box is also a breeze with this litter. Gone are the days of chiseling away at cement-like clumps or gagging on dust clouds. With Tuft & Paw, it's smooth sailing all the way.

I know subscription models are not for everyone, but I'm a big fan.

I love that I can set and forget and will get litter delivered for free on a regular schedule. I've gone for the three-month option to save 10%. The subscription management is simple, and you can easily pause and cancel as and when you need.

Finally, I feel I need to address the flushable claims of this (and other) cat litter brands. Some people think flushing cat litter is wrong, but it's perfectly acceptable when done correctly.

According to Tuft & Paw:

The safety of your kitty and the environment is always our top priority! According to the CDC, cats kept indoors that do not hunt prey, and are not fed raw meat are not likely to be infected with Toxoplasmosis. We'd recommend that you only flush feces of indoor cats, in municipalities which allow it.

So, my eco-friendly cat lovers, if you're on the hunt for litter products that are reliable, effective, and kind to Mother Earth, look no further than Tuft & Paw range of cat litters.

It's a game-changer in feline waste management, and I'm willing to bet your kitty (and your nose) will thank you for it.

Oh, and the Tuft & Paw Cat Education Center is an excellent resource for cat parenting advice and tips too!

Verified Customer Reviews

  • Best Litter Yet
    This is the litter that finally addresses all the issues we’ve had with previous litters. First and foremost, our cat loves it. It had incredible scent control, no dust, and the least tracking of any of the litters we’ve tried by far. We also appreciate its eco-friendliness. We’ll be customers for life.

  • Game Changer
    I have been searching for a litter type that does not stick to my cats feet. I have one cat on medicine that gives him really messy poops, and this litter has really helped litter not get stuck to his paws. I will be using this litter exclusively going forward. It is worth the extra cost. This stuff is the real deal.

  • No More Tracking!
    I was about to lose my mind with the dust and the messy litter tracking on my hardwood floors! I tried 5 different brands til I found Tuft & Paw. It. Really. Works. No more sweeping twice a day. No more bagging clumps. Just flush and go! Miss Fiona loves it too :)

    ★★★★★

Materials: 100% natural corn and plant fibers
Price: From $14.99 (8 lbs)
Ethics: Plant-based odor control, Donates litter to cats in need
Shipping: Multiple locations

With a name like World's Best Cat Litter, I simply had to test it and see if it was as good as the manufacturer thinks.

Well…it might not be the world's best (Tuft & Paw takes that accolade for me), but it's pretty darn good!

It's made from 100% natural corn and plant fibers, making it an excellent wheat-free option if you or your kitty has wheat allergies.

The clumping is first-rate compared to other cat litter I've tested. It's unscented, but absorbs odors quickly, leaving my home smelling fresh with no artificial scents.

Plus, it's lightweight and easy to handle. However, if you go for the 32 lb bag (best value), you might find it initially heavy to move around.

This is another flushable cat litter. Just remember to follow the manufacturer's guidelines and bear in mind the quote from Tuft & Paw in the previous review.

If you're moving to this cat litter from a previous brand, the manufacturer has a few tips to make the switch as successful as possible:

  • Transition Slowly: To introduce World's Best Cat Litter to your cat, mix one-third of it with your current clean litter. Gradually increase the amount of World's Best Cat Litter to two-thirds once your cat is accustomed to it. Eventually, switch entirely to using only World's Best Cat Litter.
  • Pick A Good Location: One litter box per cat is recommended. The litter box should be placed in a quiet location that is easily accessible and away from the cat's food and water.
  • Keep It Clean: It's recommended to scoop the clumps daily and keep the depth of litter between 2" and 3".

If an unscented multi-cat litter is unsuitable for your needs, you can check out the scented options by browsing the full range of World's Best Cat Litters here.

Materials: 100% reclaimed wood
Price: From $19.99 (13.20 lbs)
Ethics: No artificial fragrance, No synthetic chemicals, No toxic dyes
Shipping: Multiple locations

ökocat is easily the best wood litter I tested.

It's made from 100% reclaimed wood and offers exceptional natural odor control (something that all cat owners can appreciate!).

The box has an easy pour spout, and you don't have to worry about artificial fragrances, synthetic chemicals, or toxic dyes…there are none!

Plus, it's 99% dust free and speedy to clump, which means scooping out the litter box is easy, so no more dreaded cleanup dust clouds!

The one downside I found was that it does track a small amount with my two cats. Not a significant issue (and definitely nowhere near as bad as clay-based cat litter) but something to bear in mind.

I tested the Original option, but Less Mess and Super Soft options are also available. You can view the full range here.

ökocat is an excellent choice for eco-conscious cat owners looking for a dust-free and plant-based biodegradable cat litter. It does an excellent job and is reasonably priced.

Materials: 100% recycled paper
Price: From $9.98 (12 lbs)
Shipping: Multiple locations
Ethics: Biodegradable & Compostable, Uses post-consumer waste from non-profits, 

I love the idea behind this cat litter. It's made from 100% recycled paper, and the manufacturer estimates that using this product will (during your cat's lifetime) keep 3,000 lbs of waste out of landfills.

There is very little dust and nothing to aggravate any of the most common allergies (wheat, nut, etc.)

I find that the pellets are absorbent, but they do hold on to odors which can become stinky after a few days. Not an issue if you regularly scoop and top up (but something to bear in mind).

The slight increase in smell was also because I tested the original pellets (meant for use with one cat) with my two cats. If odor control is top of your list of priorities, go for the Multi-Cat Pellets instead.

The price point is also excellent for a product with many great benefits. The 25 lb bag is especially good value for money.

At first, my cats were a bit wary of this litter (they can be very fussy!). But they quickly got used to it and were soon happily using it multiple times daily.

Materials: 100% walnut shells
Price: From $15.99 (14lbs)
Shipping: Multiple locations
Ethics: Biodegradable & Compostable, 30% recycled packaging, Solar power

Before testing for this article, I'd never used walnut kitty litter before. Some I tried were rubbish, and some were just okay. But this offering from Naturally Fresh is very impressive!

The walnut shell material is incredibly absorbent and goes a long way. In fact, the manufacturer claims that one bag of this litter will last as long as three bags of clay litter. And I have to agree!

The odor control of Naturally Fresh is also superb! Not only does it trap odors, but it also neutralizes them with an organic odor neutralizer.

This super soft litter was an instant hit with Cleo and Pumpkin.

It's gentle on their paws and doesn't stick - meaning no tracking through the house! They even seem to be covering up her business more thoroughly, too (they must like the feeling on their paws).

This excellent quick-clumping litter is 100% natural and environmentally friendly as it degrades and composts easily. Plus, the packaging is also 30% recycled, which I appreciate because it means less landfill waste.

Natural Fresh is another cat litter company that offers a range of options depending on your specific needs. You can check out the full range here.

Why You Should Choose Environmentally Friendly Cat Litter

Traditional clay litters can harm the environment, as they're mostly non-biodegradable and often sourced from strip mining.

Also, clay cat litter often has added silica.

Silica dust can result in the following symptoms:

  • Cough
  • Fatigue
  • Shortness of breath
  • Chest pain

And according to CDC, long-term exposure may result in serious illnesses, such as:

  • Lung Cancer
  • Chronic Obstructive Pulmonary Disease (COPD)
  • Kidney Disease
  • Autoimmune Disease

The Best Eco Friendly Cat Litter Materials

Wood

Wood cat litter is a popular and eco-friendly alternative to traditional clay litter.

It's made from various types of wood, including pine, cedar, and even recycled sawdust.

The production process typically involves grinding the wood into small particles, heating it to high temperatures to remove moisture and kill bacteria, and then compressing it into pellets or granules.

Some manufacturers also add natural binders or fragrances to enhance the litter's effectiveness and appeal.

Many brands of wood litter are biodegradable and compostable, making them one of the best eco-friendly choices for pet owners.

Pros

  • Natural wood scent masks odors
  • High levels of absorbency
  • Sustainable when sourced responsibly (such as from FSC-certified sources)
  • Biodegradable
  • Minimal dust levels

Cons

  • Not always a great clumper

Corn

Corn-based cat litters are made from (you guessed it!) corn.

This sustainable, versatile crop is known for its many uses, but who knew it could also keep our feline friends' litter boxes fresh and clean?

It starts with grinding the corn cobs into small granules. These granules are then processed to remove any remaining moisture and kill off any pesky bacteria.

After that, some manufacturers add natural ingredients like baking soda or plant-based extracts to boost odor control and keep your kitty's bathroom smelling fresh as a summer breeze.

Pros

  • Made from renewable sources
  • Biodegradable
  • Clumps well
  • Natural cereal scent masks odor
  • Low dust levels
  • Lightweight

Cons

  • Some cats don't like the texture of corn litters and refuse to toilet on them
  • Might attract flies

Wheat

That's right, the same golden grain that gives us our daily bread is also keeping our feline friends' litter boxes fresh as a daisy.

Wheat cat litters start life like any other wheat, swaying in the breeze and soaking up some good ol' American sunshine.

To turn those beautiful stalks into a primo natural litter, they're first crushed and separated into their individual components (the bran, the germ, and the endosperm).

It's the outermost layer, the bran, that we're after here. This stuff is packed with natural starches and enzymes that give wheat cat litter its super-absorbent and odor-fighting powers.

After the bran has been collected, it's processed to remove moisture and kill off unwanted bacteria. And just like that, you've got a fresh batch of one of the best natural litter types, all ready for action.

Pros

  • Made from a renewable and biodegradable resource
  • Lighter than clay litter with a smaller carbon footprint
  • Soft on paws
  • The natural enzymes help break down odor-causing bacteria

Cons

  • Wheat litter can be slightly more expensive than other types of litter
  • Some cats may track wheat litter outside of the litter box, so you may need to sweep more
  • Wheat litter doesn't clump as well as some

Paper

Paper cat litter starts its life as your everyday, run-of-the-mill recycled paper (think newspapers, magazines, or even cardboard boxes).

To transform these paper products into a cozy bed for our feline friends' potty breaks, they're first shredded into small, confetti-like pieces. Then, they're treated with heat and pressure to zap away any lingering moisture and pesky bacteria.

Some manufacturers may even toss in a dash of natural ingredients (baking soda is popular) to help keep odors under wraps.

Pros

  • Made from recycled materials
  • Biodegradable and compostable
  • Cats with sensitive tootsies will appreciate the soft, cushy texture of paper cat litter
  • Low dust levels

Cons

  • While paper litter is averagely absorbent, it may not hold up as well as other types of litter when it comes to controlling moisture and odor
  • Paper litter doesn't form hard clumps, which can make scooping a bit trickier
  • Depending on the brand, paper cat litter can be a pricey

Coconut

Yes, coconut litter is a thing. And it's pretty cool!

To make this innovative type of natural litter, the humble coconut is husked and ground into granules.

These granules are then treated with heat to kill any bacteria and remove any water content.

The result? A lightweight, super-absorbent litter option that's dust-free and offers superb odor control.

Pros

  • Made from a renewable and biodegradable resource that would otherwise go to waste
  • Coconut litter is lighter than many other litters
  • Excellent absorbency

Cons

  • Coconut cat litter can be more expensive than other option
  • It may not clump as well as some others, but it's not too bad
  • Not readily available

Grass

Grass cat litter is made from the sustainable grasses we all know and love (wheatgrass, oat grass, barley grass, ryegrass, etc.).

To make it, the blades and seeds of these sweet-smelling greens are collected and then dried in a process similar to making hay.

Once dry, they're ground into fine particles and treated with heat to remove moisture and kill off bacteria.

This results in a soft, fluffy cat litter that's a hit with most cats.

Its earthy scent masks odors naturally, and its lightweight nature makes it easy to scoop and dump.

Pros

  • Made from a renewable resource
  • Lightweight (easy to carry and fewer carbon emissions during transportation)
  • Forms tight clumps that are easy to scoop
  • Biodegradable and compostable

Cons

  • Can be expensive
  • Some brands of grass cat litter can be a bit dusty
  • Crass cat litter might not be as widely available as other types

Walnut

Walnut litter is made from ground-up walnut shells.

These shells would typically be tossed aside as waste, but some genius figured out they're perfect for creating a sustainable, eco-friendly alternative to traditional clay litter.

Talk about turning trash into treasure!

To transform these plucky little shells into top-notch cat litter, they're first ground into small granules, just the right size for your kitty's delicate paws.

Next, they're heated to banish any lingering moisture and evict unwanted bacteria. Some manufacturers might even sprinkle in a pinch of natural deodorants.

Pros

  • Made from sustainable upcycled walnut shells
  • Biodegradable and compostable
  • Superb absorbency
  • Excellent odor control
  • Forms tight clumps

Cons

  • Can be expensive
  • Prone to dust and tracking issues
  • Avoid if a member of your house has tree nut allergies

Review Criteria: How I Chose the Best Natural Cat Litter

I considered the following factors when selecting the best eco-friendly, natural cat litter for my feline friends.

Materials

What the litter is made from was the most significant factor in my decision-making process.

I prioritized sustainable and biodegradable materials.

Company Ethics & Eco-Credentials

I examined the company's stance on sustainability, animal welfare, and working conditions.

I also wanted to ensure their production processes were eco-friendly and ethical.

Green Disposal

The best natural cat litter should biodegrade quickly and naturally or be flushable.

Clumpability

A good eco-friendly cat litter should form solid clumps so that you can easily scoop and dispose of waste without making a mess.

I also tested several non-clumping litter options too.

Pellet Size

I tried to include a range of pellet sizes in the list of recommendations.

For long-haired cats, litter with small pellets is not a good idea, as it can get stuck in their fur and become matted.

Check the label on the bag before buying, as some litters are not recommended for long-haired cats.

Odor Control

Good odor control is a must for any litter. I looked for natural ingredients that help to neutralize odors, such as baking soda, pine, or lemon.

If you own multiple cats like me, it's advisable to use litters marketed as 'multi-cat' because they contain more odor neutralizers that prevent odors on contact.

Alternatively, consider having one litter box per cat (and maybe even one spare for good measure).

Dust and Tracking

Your litter should not produce too much dust or generate allergens.

I focused on litters designed to reduce dust and tracking so I didn't end up with litter granules all over the house!

Price

I tested a range of price options.

Eco-friendly cat litters tend to be more expensive than traditional clay-based ones, so you may have to pay a bit more for your greener choice.

Responsible Cat Litter Disposal

  • Compost: One option is to add the litter to your compost pile or bin. Just remember that not all biodegradable litters are created equal, so double-check the packaging to ensure it's compostable. And please, no composting of solid waste…that's a no-go for human health and safety reasons.
  • Bury: If you've got a yard/garden, you can dig a small hole and bury the used litter. This method allows it to break down naturally over time. Just make sure to keep it away from any vegetable gardens or water sources and follow local regulations regarding waste disposal.
  • Trash: If composting or burying isn't an option, you can still dispose of biodegradable litter in the garbage. While it won't break down as quickly in a landfill, it's still a better choice than non-biodegradable alternatives. To minimize your environmental impact, consider using eco-friendly trash bags.

Whichever disposal method you choose, give yourself a pat on the back for making an eco-conscious decision in the first place.

DIY Cat Litter

Making your own cat litter is a great way to save money and reduce waste while still being eco-friendly.

This YouTube video from Howcast gives some great tips on making cat litter from old newspapers and baking soda.

A Quick Word About Indoor Air Quality

Moving from clay to natural litter will help reduce the dust and pollutants in your home.

However, if you want to take your indoor air quality to the next level (or your cat has especially stinky potty habits), consider buying a few extra houseplants or investing in an eco-friendly air purifier.

 

Frequently Asked Questions

How many times a day should healthy cats use their litter box?

A healthy cat should use their litter box about 2-3 times a day, depending on factors such as age and diet.

Is eco-friendly litter better for the environment than clay litter?

Yes! The best eco-friendly litter is made with natural, sustainable ingredients that reduce pollutants in your home and have a lower impact on the environment overall.

What's the most eco-friendly cat litter?

The best natural litter for you will depend on your cat's preferences and lifestyle, as well as your budget and environmental goals. All the litters listed in this article are good options, and I'm sure you'll find one perfect for you and your kitty.

What size litter box does my cat need?

Your cat should have a litter box roughly one and a half times its body size. This gives them enough room to move and dig.

Why does my cat toilet outside its litter box?

There are various reasons why cats might start to toilet outside their litter box, such as health problems or fear. If this becomes an issue, it's best to consult with your vet so you can find out the cause and take steps to resolve it.

Why has my cat stopped urinating?

If your cat has suddenly stopped urinating, it's crucial to seek veterinary advice immediately, as this could be a sign of a feline urinary tract disease (FLUTD).

Common FLUTDs include bladder inflammation or urinary stones/crystals, affecting male cats more often.

If you're even in doubt, it's best to get professional help to address the issue quickly and keep your kitty safe and healthy.

Is clay cat litter biodegradable?

Clumping clay litter is typically made of natural minerals such as calcium montmorillonite or sodium bentonite. These minerals do not break down in a landfill or compost pile, so they are not considered biodegradable, despite being naturally occurring.

What is crystal cat litter?

Crystal cat litter is another name for litter made from silica gel.

The Final Word

Switching to eco-friendly cat litter is an intelligent choice that benefits the environment and our beloved pets.

My favorite benefits of natural cat litter include the following:

  • Non-toxic (so safe if your pet eats some)
  • Less dust than clay litters (leading to better indoor air quality)
  • Safer for cats (and humans) with allergies or sensitive skin
  • Nice natural fragrances

By considering factors like materials, biodegradability, performance, ease of use, and cost, you can select the purr-fect eco-friendly cat litter for your furry companion.

So, let's show Mother Earth some love, one scoop at a time!
