Is Coffee Toxic to Cats? Learn the Facts.

Coffee is a beloved beverage enjoyed by many humans worldwide, but can our furry friends, such as cats, also partake in this caffeinated drink?

As a responsible pet owner, it’s essential to understand the potential risks and benefits of feeding coffee to cats. In this article, we will explore the facts and dispel any myths circulating around the internet.

What’s in Coffee?

Coffee contains caffeine, a natural stimulant that affects the central nervous system. According to the National Institutes of Health, caffeine is a psychoactive drug that increases alertness and reduces drowsiness.

Coffee also contains other compounds like antioxidants, chlorogenic acid, and diterpenes, which have various health benefits for humans when consumed in moderation.

Can Cats Consume Coffee?

The short answer is no, cats should not consume coffee or any caffeinated products.

Caffeine can be toxic to cats and cause adverse health effects. The lethal dose of caffeine for cats ranges from 20-150 milligrams per kilogram of body weight, depending on the cat’s sensitivity and the caffeine source.

Caffeine Poisoning in Cats

When ingested, caffeine is rapidly absorbed into the bloodstream, and it can lead to caffeine poisoning in cats.

The symptoms of caffeine poisoning in cats may include:

  • Restlessness
  • Vomiting
  • Abnormal heart rate
  • Tremors
  • Seizures
  • In severe cases, coma or death

If you suspect your cat has consumed caffeine, it’s vital to seek veterinary attention immediately.

Why Is Coffee Toxic to Cats?

Caffeine affects cats differently than humans because they cannot metabolize the substance as efficiently. Caffeine can also accumulate in a cat’s system because they lack an essential enzyme called cytochrome P-450, which breaks down caffeine in the liver.

Other Hidden Sources of Caffeine

Coffee is not the only source of caffeine that can be dangerous to cats. Other products that contain caffeine or related compounds include:

  • Tea, including green tea and black tea
  • Energy drinks and soft drinks, including Coca-Cola and Pepsi
  • Chocolate and cocoa products
  • Caffeine pills
  • Various medications like cold and allergy relief drugs

If you have any of these products in your home, you should keep them out of your cat’s reach.

Caffeine Alternatives for Cats

If you want to give your cat a treat, there are plenty of alternative options that do not contain caffeine or other harmful chemicals.

Some healthy cat-friendly snacks include:

  • Fresh fruits and vegetables like carrots, cabbage, and broccoli
  • Cooked meat like chicken and fish
  • Catnip or other cat toys
  • Cat treats specially formulated for felines

It’s always best to consult with your veterinarian before introducing new foods to your cat’s diet.


Cats cannot drink coffee or consume any caffeinated products because caffeine can be toxic to them. It’s essential to be aware of the potential risks and symptoms of caffeine poisoning in cats and to seek veterinary attention if you suspect your cat has ingested caffeine.

As responsible pet owners, we must always research and understand the possible dangers associated with feeding our furry friends human food or beverages.
