Corn Cat Litter

Hi there all you crazy cats! Skye Blake coming to you with a corny idea! Corn cat litter!!

paw prints coming in from a distance

Corn litter is made using cobs, kernels, and fibers from the corn plant, a.k.a. maize.,

Grain-based litters, such as corn, wheat, soy or grass, work fine for some cool kitties, but many cats eat grains and will eat the litter, causing potentially serious digestive problems.

Aflatoxin & Corn Litter

corn kernels used in cat litter

Grain-based litters can get moldy and ferment if not changed regularly, especially in hotter weather.

They can also attract bugs and rodents if not properly stored.

The main concern with mold in corn cat litter is aflatoxin, a poison given off by mold as a defense.

It’s associated with various diseases in people, pets and livestock through eating or inhaling it.

Aflatoxin grows in moist, warm conditions and even though crops are tested at various stages of growth, storage and production, it’s impossible to completely prevent it.

Corn, peanuts and cottonseed are the most susceptible crops.1“AFLATOXINS : Occurrence and Health Risks”, Cornell University College of Agriculture and Life Sciences, Department of Animal Science – Plants Poisonous to Livestock, 2018, Updated February 28, 2019

Molds in general are more of a concern with food products but some people question using it as litter.

Even after processing, molds can grow in litter when stored in hot warehouses, trucks, etc.

Corn litter creates a perfect breeding ground for aflatoxin, especially a covered litter box (warm enclosed space) with cat pee accumulating in it (liquid).

So it’s important to store this litter in a cool, dry place and scoop/clean all litter boxes daily.

If you’re concerned about this issue, you’ll probably be better off using a different type of litter.

However, if you locate your boxes in temperature and humidity controlled areas and are diligent with scooping and cleaning, mold and aflatoxin are much less likely to be a problem.

In other words, keep your boxes where your cat lives, not in the garage or basement, and keep them clean!

See “The Cat Box… Location, Location, Location” for more about where to properly place your buddy’s boxes.

Corn Litter Brands & Reviews


Below are some corn litter brands with a few reviews. This list is by no means exhaustive. It’s for your convenience only… I make no money from it.

Arm & Hammer Naturals Scented Clumping Corn Cat Litter

cornfield under a blue sky

Both DOUBLE DUTY AND MULTI-CAT versions of this litter are made from baking soda, corn fibers and plant extracts.

They absorb well, control odor, are lightweight, good for allergies, affordable, and easy on paws and feet.

Reviewers disagree about whether or not it sticks to paws (especially medium and long haired), smell of the litter itself, ease of scooping, and the amount of dust.

Some say the clumps are soft and break apart while scooping.

Frisco Corn & Wheat Cat Litter

Frisco litter is made from a mix of corn and wheat, good for single or multi-cat households.

It has a patented odor-blocking technology that keeps odor-causing ammonia from forming.

Frisco clumps up to 3 times stronger than other litters, is easy to scoop and clean and has no chemicals, added fragrances or dyes. Claims to be low-dust and is not flushable.

The majority of reviewers were happy with this litter. No-to-low odor, clumps well, and easy to scoop (some said the clumps fall apart easily).

Tracking was about the same as clay but some found mats to be helpful. Since this litter is soft it’s easier to sweep and doesn’t hurt when stepped on.

There is some manageable dust and tracking but not more than others. They also liked that it lasts much longer than many other litters.

Those who didn’t like it felt it was a mushy mess and couldn’t get it through the scoop holes.

(There are different types of scoops with different size holes so they could have used the wrong kind for this litter.)

Here is a helpful YouTube video review. Frisco corn litter is mentioned part way through…

Garfield Clumping Cat Litter

corn plants

Bio Tiny, Non-Bio Tiny, Bio Small: This corn litter has mixed reviews. There’s a question about the use of cassava (yuca) mixed with the corn.

Cassava is a starchy edible tropical plant that’s grown worldwide. It works very well with corn starches to form solid clumps.

These clumps trap odor and can easily be scooped out without breaking or crumbling.

cat focused intently looking up

Cassava root contains the toxin cyanide. There’s a method of processing cassava root that manufacturers use to make it safe.

It’s cooked and eaten by people around the world. See “Yuca & Cane Cat Litter” for more info about cassava.

Some people have concerns about it being used in litter in case their cat eats or licks it off their paws and fur. This article explains more about it: “Cyanide Poisoning and Cassava”.

LitterMaid Premium Scented Clumping Corn Cat Litter

tabby cat cleaning after using litter

This LitterMaid corn litter absorbs twice as much as clay and clumps well.

Scoop and stir the remaining litter for best results. It neutralizes odors and is low-dust.

People who reviewed this litter either loved or hated it.

One person noted that this particular litter is not the same as what’s used in the LitterMaid Self-Cleaning Litter Box.

Nature’s Miracle Premium Scented Clumping Corn Cob Litter

dried feed corn

Nature’s Miracle is made from corn cobs, not corn kernels.

Claims are that it’s low-dust, bio-enzymatic, has great odor control, is very absorbent, and lighter than others.

The granules are smaller and softer so they don’t scratch wood floors.

It comes in an easy-pour bag with a slight pine odor at first (although some say it’s too strong), is flushable, and easy to vacuum.

There are conflicting reviews about odor control.

Some reviewers mention problems with this litter having mold and fermentation problems that are especially bad in hotter weather.

There’s also some minor problem with tracking.

NonScents Natural Corn Cob Clumping Litter

longhaired tabby

Nonscents litter uses the natural absorbency of corn to trap odors and doesn’t use perfumes or fragrances.

It’s lightweight and clumps well so you can scoop and clean easily…no sticking to the box.

This litter is low-dust with no silica and is biodegradable, flushable, and useful as mulch.

Soiled litter should only be used on flower beds, not vegetable or other food beds unless properly prepared.

Cat waste can transmit diseases, but if you process the litter into compost, removing possible pathogens, it can be used safely. If you’re not sure, just put it on flower beds.


Reviewers liked how well Nonscents clumped, so they didn’t have to change the whole box very often, making it last a long time.

Some people said they and their cats didn’t like the strong chlorine smell that hit them when the bag was opened, but said it dissipated once in the open air.

Others didn’t notice that.

There was some disagreement about tracking and odor control.


The majority of reviewers felt it controlled odor well but others didn’t.

Some mentioned it tracked a lot (fine and powdery) and is more visible than others (light color).

Some cats got it stuck in their paws.

It worked well for a cat with lung problems… not dusty, clumped well.

Rufus & Coco Wee Kitty Unscented Clumping Corn Cat Litter

Rufus & Coco Wee Kitty is the 2017 Hot Diggity Award Winner.

It claims to be flushable, even in septic systems (always test this with a small amount).

R&C is lightweight, absorbs 4 times its weight, clumps well, is easy to clean and low tracking.


Reviews show conflicting experiences with tracking, odor control, dustiness.

People liked the resealable bag and that the litter lasts a long time.

Some found it expensive and didn’t like the strong citrus smell or thick texture.

Some reviewers said it’s hard to find in the USA, although Amazon has it.

Sustainably Yours Natural Cat Litter – Multi-Cat Plus Extra Odor Control 

Indian corn

Sustainably Yours is made from corn and cassava, which are renewable and biodegradable.

It’s low-dust, low-tracking, with no added chemicals or fragrances. The corn is processed to neutralize odors instantly and keep working.

This litter claims to have superior clumping performance.

They use a special corn-cassava blend that goes through an extra processing step.

Cassava (yuca) root

Sustainably Yours is whiter than other plant-based brands. This makes it easier to notice changes in your cat’s urine. You can then get her to the vet more quickly.

This litter is the only one Jackson Galaxy endorses.

As mentioned with Garfield Clumping Cat Litter above, there are questions about the safety of cassava root.

Some people are concerned about having it in cat litter in case their cat eats or licks it off their paws and fur.

This article explains more about it: “Cyanide Poisoning and Cassava”. See “Yuca & Cane Cat Litter” for more info about cassava.

Vetbasis Herbal Lavender Scented Clumping Corn Cat Litter

lavender-good plant to repel fleas

Vetbasis is made from ground corn cobs. It’s highly absorbent, clumps, traps odors, and is for use in single or multi-cat households.

Reviewers said it’s not dusty, low tracking, light fragrance and lasts a long time with occasional top-offs.

It controls odor well, is easy to clean, but stuck to their cat’s paws. It’s not cost effective for multiple cat households.

World’s Best Cat Litter

Multiple Cats, Picky Cats, Zero Mess, Scented, and Unscented are made from whole kernel corn.

Reviewers vary widely in their satisfaction with these products. All varieties of this litter have people who love and hate them.

Most are positive reviews; many feel this brand has enough positive qualities to outweigh the negatives. It absorbs well and is affordable when buying in bulk.

World’s Best corn litter is not dust-free… some find it tolerable, others don’t. There’s also disagreement about it being flushable.

Some problems reviewers mentioned are that it has an odd dirt smell and is messy, tracking everywhere.

It doesn’t eliminate poop odor and the clumps fall apart when scooping.

Sources used on this website are either primary or secondary.

Primary are always preferable and have the most reliable information because primary sources are 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.

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