Can Cats Drink Coffee? What Happens If A Cat Drinks Coffee?

If you have a curious cat, you’ve probably seen them peering into a glass or mug left on the counter to check if the contents are worth inspecting.

Should you be concerned if that cup contains coffee? Is it even possible for cats to drink coffee, and if they do, is it safe for them?

No, is the quick response. Coffee is extremely toxic for cats to consume. Even if a few drips won’t hurt them, you should make sure your cat doesn’t get any coffee dregs.

Coffee grounds, both used and unused, as well as coffee beans, are all potentially harmful to your cat.

Is coffee safe for cats to drink?

Can Cats Drink Coffee? What Happens If A Cat Drinks Coffee?

No! Coffee should not be consumed by cats due to the caffeine content and nutritional value. Depending on the type of coffee, it may also contain a lot of milk and sugar, which aren’t good for our dogs. If your cat comes across a freshly made hot drink, such as black coffee brewed with recently boiling water, he or she may be accidentally scalded.

What does caffeine do to cats?

Caffeine is a methylxanthine, which is a type of chemical. It’s used as a mild stimulant, usually in the form of beverages or tablets, to make us more alert and give us a boost of energy. However, at really high dosages, it can cause a slew of negative side effects.

Caffeine has a considerably greater effect on cats than it does on people, therefore if they consume or drink caffeine-containing goods, it can be troublesome. Low doses may merely give them a lot of jittery energy or a slight stomach ache, however excessive doses can produce more significant side effects like heart problems and seizures.

The American Society for the Prevention of Cruelty to Animals (ASPCA) warns against offering your pet coffee. It’s next to chocolate, which is another dangerous substance for pets that contains methylxanthines, which can be hazardous to them.

Why is Coffee Bad for my Cat?

Coffee can cause hyperactivity, an increase in heart rate, and even death.

Because of their small bodies, even a small amount of coffee is harmful to cats. Their physical size prevents them from consuming big amounts of caffeine. Caffeine in coffee can be fatal to them, depending on their body size.

In addition, depending on how much coffee your cat drank, the adverse effects and symptoms will appear swiftly.

Additionally, theobromine is a molecule found in coffee and caffeine.

Theobromine is a stimulant that works similarly to coffee in that it makes you hyperactive. That is, the more caffeine you consume, the more stimulated you will feel, and the more adverse effects and symptoms you will experience.

Although a cup of coffee gives us the extra boost we need to get through the day, our bodies can only tolerate so much theobromine.

What Symptoms Should I Look For If My Cat Drinks Coffee?

In as little as 30 minutes, a cat who has taken coffee will exhibit symptoms.

Because coffee contains caffeine, which provides you an energy boost, the most typical symptom to check for in your cat is restlessness (if they appear to be hyperactive).

Feel your cat’s heartbeat to check how fast it is beating.

Your cat may exhibit the following symptoms in addition to being hyperactive:






It’s crucial to keep track of the symptoms your cat exhibits and when they first appear. This information can assist your veterinarian better understand your symptoms and assess the severity of the poisoning.

My cat drank coffee – what do I do?

1. Remove your cat from the area

Remove your cat from the area so you can prevent them from drinking any more and clean up any spills or messes. Try to figure out how much they’ve consumed. Was it caffeinated or decaffeinated coffee?

2. Check whether your cat is ok

Do they appear to be acting normally? Or are they nervous and jittery? Do you have any nausea or diarrhea?

3. Call your veterinarian for advice

If you are concerned, contact your veterinarian. Monitoring is likely to be necessary if your cat has consumed a little amount of decaffeinated coffee. Cats, on the other hand, can react to any substance, including coffee, in diverse ways. Your veterinarian will be able to provide you with tailored recommendations based on the size of your cat, the sort of coffee he or she has consumed, and any health issues your cat may have.

4. Follow your veterinarian’s advice

If your veterinarian requests that you bring your cat in right away, make sure you do so. They may advise you to treat your pet or ask you to keep an eye on them at home.

5. Prevent future accidents from happening

Caffeinated goods should be kept out of reach of your cat. Never leave discarded coffee cups lying about, tip away any leftovers, and never leave your pet alone with hot beverages.

What happens if a cat drinks coffee?

If your cat has consumed a significant amount of coffee, you may see some caffeine-related negative effects within an hour or two of intake. Caffeine poisoning symptoms include the following:

Excessive excitability (becoming more active and alert)

Diarrhea and/or vomiting

Tachycardia is a fast heart rate (increased heart rate)

Arrhythmias of the heart (an abnormal heart rhythm, they may have skipping or missing heartbeats)





The severity of the symptoms will vary depending on the amount of caffeine in the coffee and how much your cat consumed. Other items may include large amounts of caffeine, which can be harmful to cats. Whole coffee beans, discarded coffee grounds, loose tea or tea bags, energy drinks, caffeinated soda, and some diet pills fall into this category.

If your cat drinks a particularly milky cappuccino or latte, the dairy ingredient may cause intestinal problems. Lactose intolerance is a condition in which cats are unable to digest the natural sugars found in milk.

What will my vet do if my cat has drank coffee?

If your cat has only had a drink or two of coffee, your veterinarian may simply ask you to keep an eye on him or her at home, especially if there are no signs of caffeine toxicity.

They may want to visit your cat at the clinic if he or she has consumed a dangerous amount of coffee or any of the other caffeinated products mentioned previously. They’ll start by evaluating them and looking for any symptoms of twitching or tremoring, as well as any heart abnormalities. They may admit your pet to the hospital if they have worries about them.

They may try to make your cat puke in order to get them to bring up the coffee. This may need an injection or, in certain situations, anesthetic-assisted stomach flushing. This will help your cat avoid absorbing any further caffeine and reduce the danger of poisoning.

If your cat is already displaying signs of poisoning, they may need fluids, which are normally administered intravenously via a drip. This can help ‘flush things out’ and speed up the caffeine metabolism while also keeping your cat hydrated. Because caffeine can be reabsorbed via the bladder wall, providing them fluids will stimulate them to urinate frequently, allowing them to eliminate the caffeine more quickly. A urinary catheter is another option.

Blood tests may be recommended to establish your pet’s health state and screen for any underlying issues. If your cat is suffering from cardiac problems or seizures, medication may be prescribed to help. A ill animal may need to be admitted to the hospital for a few days.

It’s worth mentioning that this is a relatively uncommon occurrence in cats. The majority of cases of caffeine poisoning seen by vets are in dogs, because they are more inclined to ingest huge amounts of stuff they shouldn’t!

Will my cat be okay if they drank coffee?

Most cats are unaffected by coffee consumption, especially if it was just a modest amount. A single taste is unlikely to create any difficulties, but if they consumed the entire cup, you might observe some negative consequences. However, due to the harsh taste of coffee, most cats are unlikely to consume that much.

According to the pet poison helpline, one or two sips of coffee are unlikely to cause too much harm. Caffeine poisoning is thought to be caused by more concentrated forms of caffeine, such as coffee grounds, caffeine tablets, and tea bags. Also keep in mind that different types of coffee have different caffeine levels; for example, espresso may be more hazardous than a weak latte. The total risk of poisoning will also be determined by how much your cat has consumed.

If you are unsure how much coffee your cat has taken, you should get guidance from your veterinarian, especially if your cat is displaying any signs of illness.

Can coffee kill cats?

Yes, coffee has the potential to kill a cat in theory, but this is extremely improbable.

Caffeine ingestion can produce certain symptoms as early as 9 mg/pound of body weight, 20 mg/pound can cause significant illness, and 75-100 mg/pound of bodyweight can cause convulsions and death.

Caffeine content in a typical cup of coffee is estimated to be around 95 mg, but this varies depending on the brand and type of coffee bean used. This means that a 10 pound cat would have to consume 10 cups of coffee to die! However, after drinking one cup, people may experience some of the milder negative effects.

If it’s decaffeinated coffee, it’s even less likely to cause problems in cats, however anything that isn’t part of their regular diet can cause moderate stomach disturbances.

Keep in mind, though, that if your cat ate a few diet tablets, the caffeine content might make your cat very sick. Always keep items like these out of your pet’s reach, preferably in a closet out of sight.

How Can I Prevent my Cat from Coffee Poisoning?

Keep your coffee safe and out of reach of your cats as the first step in preventing coffee poisoning in your cat.

Though it may seem apparent, leaving your cup of coffee unattended and ready for your curious cat to dive into is an easy method to prevent this.

It’s also crucial to learn which other human meals and liquids are harmful to your cat.

Any poisonous foods, like coffee, should be kept hidden and out of reach of your cat.

It’s also a good idea to teach your relatives and friends what kinds of food and drinks they shouldn’t offer your cat.

It’s also a bad idea to make it a habit and train your cat to eat human food. Your cat could be given any acceptable human food for animals to eat as a treat rather than a meal.


In general, coffee poses a modest risk to cats because a toxic dose would require a large amount of consumption. Most cats will just drink a few swallows at the most. If your cat drinks a lot of coffee or eats other caffeinated goods that are more concentrated, you should call your veterinarian right once, especially if your cat is sick. Keep all caffeinated things well out of reach of your pet in the future, and don’t leave drinks unattended to avoid problems in the first place! Coffee is a beverage that we, not our pets, should partake in.
