The 10 Best Eco-Friendly Cat Litter

1. Kitty Poo Club Delivery Service – Best Overall

Our top pick for the best eco-friendly cat litter is Kitty Poo Club Subscription Service. It has several varieties of eco-friendly clumping and non-clumping litters, such as corn & wheat, organic soy, and diatomite. Each litter is hypoallergenic and is designed to provide maximum absorbency.

In addition to their environmentally conscious litter options, you’ll receive a recyclable litter box that you swap out each month, making each litter change one you can feel great about. A few more perks of this subscription service are the selection of add-ons and free shipping.

Overall, we think this is the best eco-friendly cat litter available.

2. Frisco Pine Pellet Unscented Non-Clumping Wood Cat Litter – Best Value

Frisco Pine Pellet Unscented Non-Clumping Wood Cat Litter is the best eco-friendly cat litter for the money. The 100% pure pine leaves a fresh aroma in your cat’s litter box and naturally eliminates odors with no fragrances or chemicals. The pellets absorb up to three times their weight in liquid to keep the litter box fresh and clean with daily scooping.

Because this litter uses pine pellets, it doesn’t create dust or tracking. It is powerful enough for single or multi-cat homes. Some customers mentioned that Frisco's pine litter works well for pets like rabbits. However, it's unsuitable for some litter box systems since the pellets may be too large.

3. Catalyst Pet Softwood Natural Clumping Cat Litter - Premium Choice

For cat owners seeking the gold standard in eco-friendly performance, Catalyst Pet Litter is our premium pick. Where many eco-conscious litterers ask you to compromise on clumping or odor control in exchange for green credentials, Catalyst refuses to make that trade-off. It’s built from 100% upcycled softwood - sawdust byproducts sourced from U.S. lumber mills that would otherwise be destined for landfills - and uses natural guar gum as a binding agent to achieve tight, scoopable clumps.

Owned by Lignetics, Inc. and manufactured in Louisville, Colorado, Catalyst has one of the most credible eco stories we’ve come across: the production process requires no additional land, water, or agricultural inputs, and the finished product is fully biodegradable. Unsoiled litter can even be home-composted, and soiled litter is accepted by many municipal composting programs.

4. World’s Best Lavender Scented Clumping Corn Cat Litter – Premium Choice

World’s Best Lavender Scented Clumping Corn Cat Litter is the premium choice for eco-friendly cat litter. It uses 100% all-natural scented lavender oil to eliminate the ammonia smell of cat urine, even in homes with multiple cats. The litter clumps for quick and easy cleanup.

With the compressed corn formula, the litter creates no irritating dust that may bother you or your cats. It's flushable and safe for both septic and sewer systems, so you can reduce the waste that ends up in landfills. The World's Best litter is also appropriate for some automatic self-cleaning litter boxes. However, several users mentioned that the litter has a strong, unpleasant odor and tracks easily.

5. Skoon All Natural Fine-Grain Unscented Non-Clumping Cat Litter – Best for Kittens or Puppies

Skoon All-Natural Fine-Grain Non-Clumping Cat Litter is formulated for odor control and uses highly absorbent diatom pebbles. The porous material absorbs odors to keep your litter box smelling fresh and inviting for training kittens through to adulthood. The litter is non-tracking and has minimal dust so that it won’t upset your kitten’s breathing.

One of the best features of the Skoon litter is that it feels like traditional litter in an eco-friendly formula, so your cat won’t notice the difference. It is also hypoallergenic and made with no chemicals or artificial scents. It’s four times lighter than regular litter, making it more convenient to carry and change. The only downside is that the fine particles track more easily.

6. sWheat Scoop Multi-Cat Unscented Clumping Wheat Cat Litter

sWheat Scoop Multi-Cat Unscented Clumping Wheat Cat Litter is a natural, ultra-absorbent litter that uses renewable and biodegradable wheat to trap and neutralize odors. Unlike other clay litters, it has no dyes, perfumes, dust, or other potentially harmful ingredients.

sWheat is ideal for multi-cat households and is an eco-friendly option for a clumping formula. It’s fully biodegradable and can be flushed, reducing your overall waste that ends up in a landfill. It can also be composted. However, some customers noticed that it tracks and leaves a yellowish coating on surfaces, while others seemed to have no issue with tracking.

7. Naturally Fresh Multi-Cat Unscented Clumping Walnut Cat Litter

Naturally Fresh Walnut-Based Multi-Cat Quick-Clumping Cat Litter is made from 100% natural walnut shells and eliminates urine and fecal odors with a counteractant. The absorbent formula neutralizes odors better than comparable products and is biodegradable.

Because it’s made of walnut, the litter doesn’t cause irritating dust and breathing issues nor stick to paws and track through the house. The litter is ideal for multi-cat households and contains no chemicals, clay, toxins, corn, or grains. Despite the dust-free formula, some users noted that the litter causes a lot of dust. Others commented on the odors and said it doesn’t clump very well.

8. Fresh News Recycled Paper, Original Pellet Cat Litter

Okocat Original Premium Wood Clumping Cat Litter is made of sustainably sourced natural wood fiber and is free from artificial fragrances, synthetic chemicals, toxic dyes, and GMOs. The wood fiber is biodegradable and rescued from waste, reducing the impact of manufacturing. It naturally bonds with liquid and waste to minimize ammonia odors and absorb liquid on contact. The litter also clumps well for quick and convenient cleaning.

Okocat is flushable and safe for sewer and septic systems. The wood is de-dusted before manufacturing, minimizing dust that can irritate your breathing. However, several cat owners said it tracked easily, left a perfume-like odor, and was difficult to clean.

10. Frisco All Natural Unscented Clumping Grass Cat Litter

Frisco All Natural Unscented Clumping Grass Cat Litter is an eco-friendly alternative to clay litter. It uses 100% all-natural soft and easy-to-sift grass that clumps easily for cleaning and provides natural odor control and ultra-absorbency.

The ingredients are biodegradable and free from chemicals, dyes, or fragrances that may be off-putting to your cat. Because it’s made from grass, it produces minimal dust compared to other types of litter and is less likely to track. While many users were pleased with the results, others mentioned that it doesn’t absorb or clump well and sticks to the litter box's sides, making cleaning difficult.

Buyer’s Guide: How to Choose an Eco-Friendly Cat Litter

Choosing an eco-friendly cat litter is a great decision for the environment and your cat. Several types are available, and here are some characteristics you should consider:

• Materials: Plant-based materials, recycled wood, and paper are excellent eco-friendly materials that absorb liquid waste and have a low environmental impact.
• Clumping: Clumping formulas are handy because they’re easy to clean, but not all eco-friendly litter forms clumps and some don't clump very well.
• Dust-free: Clay litter is notorious for creating a lot of dust that can irritate your cat’s nose or mouth. Most litters on this list are dust-free, but some customers noted that they still had dust issues.
• Odor control: Chemicals, fragrances, and other ingredients are often used to control odors. Eco-friendly litter removes these artificial ingredients in favor of natural odor control, such as pine or lavender.
• Special eco-friendly features: Some types of litter have added eco-friendly benefits, such as a flushable or biodegradable formula. Consider these formulas if you want to reduce your overall waste or try cat litter composting.
