Grass Cat Litter

Greetings litter connoisseurs! Did you know there’s now cat litter made from grass? What will they think of next?!

Grass… what could be more environmentally perfect?

It’s green, natural, healthy, fun for us fabulous felines to roll and hunt in.

But how does it work as cat litter?

Grass Cat Litter – the Positives

Grass is made from leaves and seeds into pellets that absorb urine just like other litters.

These pellets are lightweight, soft on paws, low-dust, clump well, and control odors.

They’re also easy to scoop and people like that they’re biodegradable.

In fact, some grass cat litters are organic and non-GMO, a plus for environmentally concerned people.

Grass Cat Litter – the Drawbacks

grass - cat litter

While grass cat litter is appealing to people, especially for its environmental benefits, there are some drawbacks you must consider…

Expense

dollars bills with gold $

Grass litter, like other specialty litters, is more expensive than clay. You’ll need to look at how long the litter lasts as well as the cost per bag.

If you get 60 days of use out of one bag, the cost is more reasonable than 15 or 30 days and might be worth it for you.

Allergies

If you, a member of your household or your cat are allergic to grass, you won’t be able to use this litter… think “permanent hay fever”.

It’s Edible

Some of my fellow felines love to chew on grass. In fact, many people grow wheat grass in the house for their kitties to eat.

While you might think that makes it safe for cats to use as litter, it actually can be a problem.

We cats are instinctively hardwired to keep food and pee areas completely separate, so providing grass as both food and litter creates a conflict.

At the very least, you’ll confuse your kitty, and he might eat the litter, ending up in emergency surgery with blocked intestines!

This is especially true of kittens, who love to eat everything (non-clumping litter is best for young kittens).

If he doesn’t eat it, he might still see it as food and find somewhere else in your home to do his business… oops!

If you think your cat might be confused, use litter that’s not appealing as food.

Almo Nature

Almo Nature cat litter is produced using only vegetable fibers with nothing toxic added. It isn’t technically a grass cat litter but is basically the same.

It absorbs instantly and liquid stays trapped in a thin clump on top, keeping the box and remaining litter clean.

Reviewers say it’s lightweight, flushable, easy to scoop/top up, and stays clean quite awhile.

They say it clumps well and doesn’t stick to box, is soft, easy on paws, and has good odor control.

It tends to be dusty and track everywhere since it’s fine grained. Mats help with this problem.

Sources

Sources used on this website are either primary or secondary.

Primary sources are always preferable and have the most reliable information because they’re original and directly referenced.

Scientific abstracts and data are good examples of primary sources.

Secondary sources are weaker because they usually consist of opinions or articles that give no sources of their own.

However, sometimes they refer to primary sources.

When I use secondary sources, most are those with some authority, such as veterinarian or cat behaviorist books and articles.
