Pros and cons

Now, let us take a look at the pros and cons of grass seed litter. If you want to skip to the top pick section, simply click here.


Benefits of using grass based litter:

  • Excellent clumping
  • Very low dust
  • Good odor control
  • Easy to scoop
  • Natural, organic and unscented material
  • Soft texture (and easy for your cat to dig in)
  • Lightweight
  • Eco friendly (grass seed is a sustainable and biodegradable material)

If you are looking for a natural litter, the #1 reason to choose grass seed cat litter is its clumping abilities. The litter quickly forms clumps when exposed to cat urine, and unlike some natural litter alternatives, these clumps are very firm and solid. Since the clumps will not easily break apart, this makes it easier to scoop the cat litter.

An easy scooping routine is more important to some cat owners than others. For example if you are a multi cats household, or live in an apartment, and need to scoop more often in order to control odor.

The texture of the grass seed litter should also appeal to your cat, and make the transition easier. It is both soft on paws, and great to dig in.


Unfortunately, there is no such thing as the perfect cat litter. Not yet anyways. Despite many benefits, there are also some cons that need to be included in this guide. If the #1 benefit of grass seed litter is its clumping, then price is the #1 con compared to some of the other litter types.

Luckily, if you want to try it because of its benefits, there are a few ways you can minimize some of the cons.

  • Price
  • Tracking
  • Allergy

The fix for price:
Start by buying the cheapest grass litter option (see top pick), and go for the largest bag. You will get more value from buying a larger bag of litter. Even though the up front cost is greater, you will receive more value and save money in the long run. This is also better for the environment, because it leads to less packaging and shipping.

Buy in bulk and take advantage of sales. If it turns out that grass seed litter really is the right fit for you and your cat, planning ahead and stocking up could save you more money. Especially when you can combine it with a sale.

The fix for tracking:
Minimize tracking by using a litter mat, that will catch the litter and prevent further spreading.

If you are not ready to give up the hunt for the perfect cat litter, there is another option you can try, that might bring you one step closer.

In this video, one cat owner suggests mixing walnut litter with the grass litter, because of how they complement each other. The walnut litter does not track much, but the clumps can break during scooping. Mixing the two produced a litter with less tracking, and more solid clumps.

If you or you cat is allergic to grass, you may react to this litter. If this is the case, there are several other natural clumping cat litters to choose from. You can read more about them here.

To help you decide if this litter type will work for you, here are some general step by step instructions to use as a guideline. However, you should still follow the directions stated on the product’s packaging.

How to transition to grass cat litter

How much litter should you add
About 3-4 inches in depth is recommended.

How to scoop
Even though grass litter is made from an organic material, it can be used very similarly to clay based litter. Simply scoop as you would with most clumping litter types.

How often to scoop
Remove clumps and feces two times daily, to keep the litter box clean and healthy for your cat. This also helps with odor control.

Add more litter as needed.

How to dispose of used litter
The most obvious, and conventional way to dispose of the used litter is to simply throw it in the trash, The same way you would with a clay based litter.

There is also a more eco friendly solution that might be an alternative. Grass based litter is biodegradable, so composting could be another way to dispose of it. Click here to find out if composting is an option for you.
