10 Best Eco-Friendly Cat Litters Review

First, let’s take a quick look at why it is worth considering a more natural litter.

Clay-based litter is still one of the most popular cat litter types among pet owners. But since this type of litter isn’t biodegradable, it’s harmful to the environment. And mining the clay is very destructive.

Moreover, many clay litter brands contain crystalline silica dust, a known cancerogenic. Breathing these fine particles can lead to permanent lung damage. (1)

Fortunately, you’ve got plenty of natural options that won’t put your kitty at risk and will go perfectly with an eco-friendly cat litter box.

But what’s the most eco-friendly cat litter? Let’s see my top 10 best environmental cat litter picks.

What To Look At When Buying Eco-Friendly Cat Litter?

Let’s talk about what features you should consider when buying the best environmentally friendly cat litter. 

1. Material

Eco-friendly brands are made from renewable or biodegradable materials, such as paper, wood, corn, wheat, walnut, etc. And they’re not all equal in how they absorb liquid and control odors.

Corn and wood-based litters are generally better because of their high-absorbency rate, low dust production, and natural odor reduction.  

2. Texture

3. Number for Cats

Some cat litter types work great for a single cat but produce an awful smell when more than one cat uses the box. Check that the formula is strong enough to suppress odors from multiple cats. 

FAQs

Conclusion

An eco-friendly cat litter is not only a great way to reduce your cat’s carbon footprint but also a healthier option for your kitty. 

It may take a while to figure out which eco-friendly litter is the right one for your kitty. You can place several toilet boxes with different textures to see which will appeal the most.
