5 Best Grass Seed Cat Litters In 2021

When you’re working with regular clay-based cat litter, scooping and pouring becomes impossible. The litter smells horrid, doesn’t clump, and produces so much dust that you’re practically suffocating yourself. This is why people prefer plant-based and natural cat litters. The dust from this kind of cat litter can even make you sick.

Grass seed litter in particular is preferred for its high clumping and low dust formation. It’s natural and can be found GMO-free, which means there are no harmful additives in it. Grass seed can also be repurposed as compost for horticulture, and some can easily be flushed. 

However, grass seed litter, since it’s so small and lightweight, tends to fall everywhere, known as tracking. Plus, it’s quite pricey. Also, it should be avoided if you’re allergic to the ingredients.

But all things aside, which grass seed litter is the right one for your cat? Here are the top 5 reviewed.
