What Is Coffee?

Let’s take a look at coffee… most of us know it as something we drink, regular or decaffeinated, basic or gourmet, espresso or cappuccino, I could go on…

“Coffee” is the name of beans from the berries of the flowering “coffea” shrubs native to tropical areas of southern Africa and Asia.

Coffea arabica and C. canephora are the two most common beverage types.

Once coffee is brewed the grounds are left that are either discarded or have uses such as adding to garden beds to acidify soil.

And now, it’s got another use… cat litter!

How Is Coffee Used in Cat Litter?

Used coffee grounds are the main ingredient in coffee cat litter.

It also contains other natural ingredients like seaweed and cornstarch to provide good clumping power.

Coffee helps eliminate odors (although it has its own distinct fragrance).

Like other specialty cat litters, coffee litter is more expensive than clay, another thing to consider when deciding if it’s worth a try.

Concerns about Cats & Caffeine

Coffee must be decaffeinated before using due to the danger of caffeine, which is toxic to cats.

Caffeine is a methylxanthine that’s in coffee, chocolate and other foods.

People enjoy it for its “pick-me-up” effect, especially in the morning. It’s fine in moderation for humans but is toxic for dogs and cats.

Even tiny amounts can cause serious problems for your cat.

Caffeine poisoning is more common in dogs than cats because they’ll eat anything… and in large quantities too!

(Dogs… hmmf! Disgusting creatures!)

Some say cats don’t like the smell of coffee and will avoid it, so they use it in their garden beds to keep cats away.

Most of us fabulous felines are particular about what we eat, but there are some who’ll eat things they shouldn’t, so if your buddy is like that, don’t use any cat litter that smells like food, including coffee.

This is especially true for young kittens who just love to put anything in their mouths!

Any clumping litter is dangerous for young kittens because it can swell in their tiny tummies and cause a life-threatening blockage.

Emergency surgery, anyone?

If your cat doesn’t care about anything in litter besides whether it’s comfortable for peeing, etc., you might find that coffee litter works well for you both.

Symptoms of Caffeine Toxicity

If your cat has eaten some chocolate or licked caffeinated coffee, tea, energy drink, or soda, watch for the symptoms listed below. (Some medications also have caffeine.)

A couple of licks might not be a problem, but you should watch closely.

If any symptoms happen, usually within 1-2 hours, get her to the vet immediately.

  • vomiting
  • diarrhea
  • panting

  • abnormal heart rhythm
  • tremors

The American College of Veterinary Pharmacists has a handy chart showing the amounts of products that cause toxicity in cats.

Brands of Coffee Cat Litter

Brands and products given on this page are for your information and convenience only… I make no money from them.

They are available at each company website and/or Amazon.

Eticat Cat Litter

Eticat litter is made from decaffeinated coffee grounds, giving it odor control and eliminating the toxicity concern.

It contains seaweed extract and cornstarch for good clumping and easy scooping, has very little dust and no added fragrance.

You should still be careful, though, if you have a cat who might eat it.

Alfred Cassava Black

Alfred Cassava Black cat litter is a mixture of cassava (yuca), decaffeinated coffee grounds, seaweed extract and cornstarch.

As with Eticat litter (both from the same company), being decaffeinated eliminates the concern about using coffee grounds as cat litter.

You should still be careful, though, if you have a cat who might eat it.

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.
