This Review has been updated 4 times since it was first published in January of 2019. If you go to your local pet store, you’ll find the most prevalent choices for cat litters are clay-based. But as pet parents become more concerned about exposing their furry friends to chemicals and toxins, many are seeking out alternative options. Biodegradable cat litters are becoming more popular because clay needs to be strip-mined and is not a renewable resource. When users buy our independently chosen editorial picks, we may earn commissions to help fund the Review. Skip to the best biodegradable cat litter on Amazon.
10. Cat Spot Organic
Cat Spot Organic is simply coconut shell shavings that some pet parents love because they can empty the litter box into flower beds to add nutrients to the soil. This formula isn’t designed to clump, but absorbs urine, while only the solid waste is scooped out.
- Dispose of it every 1 to 2 weeks
- Not ideal for multi-cat households
- Lightweight shavings stick to fur
9. Eco Care Bamboo.
The environmentally conscious will feel good about Eco Care Bamboo. It consists of just shredded, organically and sustainably grown bamboo. The fiber in this material stops the formation of ammonia odors, and also has natural antibacterial properties.
- Large granules are easy to sweep up
- Recommended for short-haired cats
- Expensive for a small bag
8. Our Pets Switchgrass
Our Pets Switchgrass is made with an easily renewable plant source mixed with biochar, an activated charcoal that quickly absorbs wetness and odors while still being biodegradable. Switchgrass is a great choice as it does not require fertilization or pesticides to grow.
- Smells like a freshly mowed lawn
- Carbon is non-marking
- Dustier than clay litter
7. Garfield Bio Ultra-Clump
Garfield Bio Ultra-Clump consists of soft, tiny grains that are ideal for sensitive paws. Plus its white sandy color is helpful if you need to monitor your cats’ health by checking their urine for color changes, like with the presence of blood.
- Hard clumps won’t break
- Comes in easy to carry 5-pound bags
- Tracks all over the house like sand
6. Naturally Fresh Multi-Cat
Naturally Fresh Multi-Cat is so absorbent that one bag is equal to three bags of typical clay-based products. It produces little dust, but some users report that the dark, walnut-colored stuff it does give off temporarily stains lighter-colored cats’ paws.
- Made from a renewable resource
- Excellent odor control
- Not safe if you have a nut allergy
5. sWheat Scoop
While wheat may seem like a plant that is not substantial enough to act as kitty litter, sWheat Scoop works because the starches that are exposed when the product is ground help with clumping, and the enzymes neutralize odors.
- No dyes or fragrances
- Nontoxic for pets who try to eat it
- Emits bad smell if not scooped daily
4. Purina Yesterday’s News
Paw-friendly Purina Yesterday’s News is recommended by veterinarians post surgery, plus its gentle paper pellets leave no tiny particles to track around the house. This non-clumping solution traps odors by absorbing 3 times more by weight than clay.
- Budget-friendly price per pound
- Recycled paper and cardboard
- Needs to be replaced often
3. Okocat Healthy Pet
Okocat Healthy Pet takes eco-friendly to the next level because it uses reclaimed wood that would otherwise go to waste, but if you’re switching litter types, you may need to buy a different scoop, as the particles are larger than most litters.
- Light pleasant wood scent
- Half the weight of clay
- Packaging is fully recyclable
2. Smart Cat All Natural
Smart Cat All Natural is made from chemical-free grasses grown in the USA. This material clumps on contact, can be scooped within minutes of elimination, and the sand-like texture makes it easy to transition your cats from clay.
- Completely renewable ingredients
- Extremely lightweight
- No dusty residue
1. World’s Best Multiple
World’s Best Multiple is the same as the original formula and consists of 100% whole kernel corn, with added wood fiber to increase the odor control performance. The surrounding litter stays clean after you scoop it, so you don’t have to clean the pan as often.
- One bag can last over 2 months
- Clumps do not stick to the box
- Saves money over time
