I’m a sucker for Oreos. I love dunking them in milk or gorging on them while watching Netflix. Sometimes a bite will drop on the floor, and before I can pick it up, my cat has demolished it.

But, I’m sure the same situation has brought you here. You know that chocolate is bad for cats, but you’ve probably wondered, can cats eat Oreos?

Let’s find out why it’s not a good idea to feed your cat Oreos and make you into one smart cookie.

Can Cats Eat Oreos?

No, cats should not eat Oreos. They’re packed with cocoa and chocolate, which are lethal for your cat due to the caffeine and theobromine. These toxic substances can cause your cat diarrhea, restlessness, abnormal heart rate, and lethargy.

Plus, Oreos are rich in sugar and fat, which can cause a whole host of health problems for your cat. So it’s best to keep Oreos away from cats at all costs.

Are Oreos Bad for Cats?

If your cat manages to get hold of an Oreo cookie, they’ll be fine. That being said, if they love Oreos and eat them frequently, it could result in tooth decay, weight gain, and other severe conditions.

Oreos have several ingredients that can be harmful to cats. Let’s look at some of the common problems cats could face that are associated with Oreos.


Chocolate is bad news for cats. It contains theobromine which is highly toxic for our feline friends. The highest theobromine can be found in baking chocolate or cocoa powder.

Luckily, Oreos only contain trace amounts of theobromine. They aren’t as toxic as other foods like baking chocolate. But, it’s still best to avoid giving your cat Oreos because of the rich amounts of fat and sugar.

Oreos may also have other toxic ingredients because of the amount of chocolate in them. Chocolate is often paired with ingredients like alcohol, caffeine, sugar, fat, and xylitol. All of which can be harmful to cats.

It’s unlikely your cat will suffer serious harm if they eat a single Oreo cookie. But, if they consume a lot, you should take them to a vet immediately as they may have eaten too much chocolate. You can try this chocolate toxicity calculator for free if you’re ever not sure.


An Oreo cookie has about 2g of fat, which can be dangerous for cats. The recommended fat intake for an average adult cat is 4.6g. So a single Oreo cookie makes up half their daily fat allowance!

Cats that are overweight or obese are more likely to develop heart disease and other severe conditions. In fact, even if your cat is an ideal weight, eating too much fat can quickly cause other problems.

Fat is extremely high in calories and often leads to obesity, which opens the door for other illnesses to develop.


Oreos contain a lot of flour. But while flour isn’t toxic for cats, it can cause severe digestive issues if consumed in large amounts.

It’s also worth noting that flour doesn’t contribute anything significant to a cat’s diet. In fact, they get most of the nutrients they need from real animal meats.

Cats that consume large quantities of flour may suffer from constipation, diarrhea, and vomiting. Flour also contains a lot of calories that can cause your cat to pile on extra pounds.

Cats that suffer from gluten allergies should avoid flour at all costs.

Palm Oil

Most processed foods contain vegetable oils like palm oil. In large doses, vegetable oil can be harmful to cats because of its high amounts of saturated fats.

Palm oil is also full of laxatives. So cats can experience cramping, diarrhea, and nausea if they eat too much. Plus, palm oil is packed with empty calories that contribute to weight gain.


One Oreo cookie has an astonishing 4.8g of sugar. That’s a lot!

Sugar affects cats the same as it does for humans. So consuming foods packed with sugar quickly leads to tooth decay, diabetes, lethargy, heart disease, obesity, and weight gain in cats.

Different Types of Oreos

Oreos come in a few varieties; not all are safe for cats to eat. In general, it’s best to avoid giving them any Oreo or Oreo ice cream.

Let’s “dunk” into some of the different types of Oreos and find out if they’re safe or not.

Can Cats Eat Golden Oreos?

No. Cats should avoid eating Golden Oreos.

While Golden Oreos have less chocolate, they still contain high sugar, corn syrup, and palm oil.

Sugar is harmful to cats because it can lead to serious health problems like heart disease, diabetes, and obesity.

Can Cats Eat Lemon Oreos?

Lemon Oreos aren’t safe for cats to eat.

They are full of annatto extract and citric acid, which are extremely dangerous for cats. Annatto extract is an artificial food coloring that can induce seizures. While citric acid is known to cause CNS depression and irritation in cats.

Can Cats Eat Strawberry Oreos?

Strawberry Oreos are not recommended for cats.

Strawberry Oreos is a limited-edition, and they’re not safe for cats. As suggested in the name, they’re not made with chocolate. But Strawberry Oreos still are rich in oils and sugar, which are still harmful to cats. Sugar causes heart disease, diabetes, and heart disease in cats. While oils are a leading cause of pancreatitis.

Can Cats Eat Oreo Ice Cream?

No. Oreo ice cream should be avoided at all costs.

Most cats are lactose intolerant; their digestive system cannot process the sugars contained in dairy products. Oreo ice cream is made with both sugar and milk. Milk can cause your cat to experience bloating and digestive problems. While sugar can cause diabetes, heart disease, and obesity in cats.

My Cat Ate An Oreo, What Should I Do?

If your cat has eaten an Oreo, you should find out how much they’ve eaten, when, and what ingredients they contain. But, if your cat has eaten one regular Oreo, they should be okay.

If they’ve eaten a large quantity, you should immediately take them to a vet. Large amounts of Oreos could cause chocolate toxicity in cats.

The same applies to any other kind of Oreo; you should take them immediately to the vet. Some Oreos will contain artificial ingredients that can be highly toxic to cats.

The main concern with Oreo cookies is how much chocolate they contain. Large quantities of chocolate can cause chocolate toxicity, which is sometimes fatal.

Symptoms of Cat Chocolate Toxicity

Did you know that chocolate toxicity can happen to humans as well as animals? It’s just our digestive systems can handle larger doses.

Chocolate toxicity is highly lethal for cats, especially if they ingest excessive amounts of chocolate. In the early stages, your cat may experience symptoms like:

  • Diarrhea
  • Restlessness
  • Elevated heart rate
  • Abnormal thirst or urination
  • Vomiting

That being said, chocolate toxicity causes various symptoms that occur later on. It can cause heart failure, seizures, tremors, and coma in the worst cases.

Steps To Take

If you suspect your cat has eaten Oreos, there are several steps you should take. These are:

  • Collect a sample of what they’ve eaten or the packaging.
  • Under no circumstances should you induce vomiting unless instructed by a vet.
  • Try and find out the time of ingestion.
  • Ensure there’s access to fresh water.
  • If you suspect they’ve consumed too many Oreos, take them immediately to a vet clinic.

Keep an eye for any of the symptoms above. Lethargy is also a severe symptom they could experience. However, this could be an indication of another underlying health problem.

Treating Chocolate Toxicity

If your cat ate a single Oreo, you should keep an eye for any side effects. Take them to a vet if they experience any symptoms of chocolate toxicity or if there are loads of Oreos missing from the packages.

In some cases, a vet may recommend inducing vomiting if your cat has consumed them within 2 hours. 

Do not induce vomiting unless instructed by a vet.

If your cat has consumed loads, they may need to be hospitalized. Unfortunately, there is no antidote for chocolate toxicity. Your cat will be given fluids and continuously monitored for improvement. If they’re not eating, they may need IV fluids too.

Once the chocolate has passed through in your cat’s feces or vomited, they’ll likely be discharged after 48 hours.

You’ll receive instructions from them on what food to offer them and the quantities. It’s essential to keep monitoring them afterward. If any symptoms reappear or worsen, take them immediately back to the vet.

Regular exercise can also help.

Alternative Foods Safe for Cats

Cats mainly thrive on a meat-based diet with high-quality ingredients. But some cat owners prefer to introduce new, exciting flavors into their diet.

Here are some low-fat, low-calorie alternative foods you can give your cat:

  • Fruits: Blueberries, Blackberries, Cucumber, Pineapple, or Watermelon.
  • Vegetables: Carrots, Celery, Lettuce, or Green Beans.
  • Meats: Chicken, Beef, Fish, Salmon, or Turkey.

These treats are all nutritious for your cat. Plus, they’re pretty common to find around the house. Just remember, moderation is key. Too much of a good thing will likely cause your cat to experience health problems.

No Oreo, Just No.

Oreos might be one of my favorite snacks, but they’re harmful and often toxic to cats. The large amounts of chocolate in Oreos are likely to cause chocolate toxicity, which can be fatal.

Of course, we all want to introduce a bit of excitement into our cat’s diet. But at what cost? As cat owners, we have to keep our furry friends safe. This includes keeping them away from toxic foods like chocolate, raisins, and grapes.

So, the next you’re considering giving your cat an Oreo, think about their health. Is it honestly worth the risk?


Is Chocolate Poisonous for Cats?

Yes, chocolate can be extremely lethal for cats. Chocolate contains a substance known as theobromine. It’s found in all kinds of chocolate, from baking chocolate to white chocolate. It only takes a small 0.2 oz of chocolate for cats to experience toxicity.

Can Oreos Kill Cats?

In large doses, yes, Oreos are considered lethal for cats. They’re made up of cocoa and chocolate, containing caffeine and theobromine. These toxic substances can cause diarrhea, abnormal heart rate, lethargy, and restlessness.
