Can Cats eat Olives?

How many times do we want to feed our little furry family member what we are eating at the moment we are eating it?

It is their ability to look at us with its big penetrating and begging ‘’Cats in the Boots Eyes”, that let your heart melting. The inner resistance level to feed him/her what he/she is craving for in the moment is sometimes irresistible. But the question at the end remains. Can a cat eat the same food as we eat? Can a cat eat olives?

Before I answer this question to the fullest, I dig deeper in what olives are and why some cats seem crazy about them.


What would a pizza or real Italian salad be without olives?

The olive is a small fruit grown on olive trees called ‘olea europaea'.

The olives relatives are:

  • Mangoes
  • Cherries
  • Peaches
  • Almonds
  • Pistachios

This little power fruit boasts with a great shot of vitamins and other powerful antioxidants.

According to studies they are good for the heart and protect against osteoporosis and cancer.

Healthy fats in olives are extracted to produce olive oil which is a main support of the Mediterranean diet.


Olives contain 11-15% fat.

Eating olives you decrease the risk of inflammation and reduce the risk of heart disease and maybe help to fight cancer.

In a nutshell:

The olive is a nutritious powerhouse fruit. It is:

  • High in fat
  • An abundance of oleic acid giving several health benefits

Carbs and Fiber

The olive comes in a low carb content.

Another important point during fermentation is lactic acid protecting the olives from harmful bacteria.

  • Spanish green olives

Only 4-6% is carb. A staggering 52-86% is fiber completing the carb content.

You find a great variety of several vitamins and minerals in olives.

  • Vitamin E:
  • Iron: This you find mostly in black olives. Important for the transport of oxygen in red blood cells.
  •  Copper: This essential mineral decreases risk of heart diseases.
  • Calcium: Essential for bone, bone muscle and nerve function.
  • Sodium

 In a nutshell:

  • A power fruit to help decrease heart diseases and helping to transport oxygen in the red blood vessels.

These most common olives are:

  • Greek black olives
  • California olives
  • Olives in its nature are bitter. This is why they are processed before eaten. They are cured and fermented.

The process removes bitter compounds like oeuropein most abundant in unripe olives.

Black olives have the lowest levels of bitter compound. Olives processing time can vary from a few days to a few months depending on how bitter the fruit, which affects the taste, color, and texture of the fruit.

Current studies are finding out if fermented olives have probiotic effects in the body. This could result in improved digestive overall health.

 in a nutshell

Before an olive is eatable, it undergoes a fermentation process to reduce the bitter taste. This may help increase the digestive system.

The health benefits of an Olive

Olives are a main part of the Mediterranean Diet. The reason is that it has a lot of health benefits like:

  • Heart health
  • Cancer prevention
  • Antioxidant Properties

Olives are rich in antioxidants fighting inflammation and reducing the growths of unwanted microorganisms.

They may have the power to reduce oxidative damage caused bacteria.

Improved Heart Health

Olives and olive oil may help to regulate and reduce blood pressure.​s​​​​​​​​​​​​​​​​​​​​​​​​

Bone Health

Scientists assume that olives reduces the risk of bone cancer.

Cancer Prevention

Because olives are rich in antioxidants they may help reduce the risk of cancer.

Adverse Effects and Ind​​​​​​​ividual Concerns

As we all know olives contain a high level of salt because of the liquid they are in while packaged. They might have a small amount of heavy metals and acrymalide (find most likely in the black California olive).


Olives are an excellent side dish for humans because of their low carbs and high healthy fats .

Are olives as BENEFICIAL for cats as they are FOR HUMANS? 

After knowing the beneficial attributes for people, what about the cat?

It is obvious that cats wouldn’t eat olives if they would live in the wilderness, because they are carnivores. Their body produces their own Vitamin E and C.

Still, taking the medical benefits in consideration, the inflammatory and antioxidants helping free radiants and decrease illnesses. It might decrease cancer risk and those cats suffering arthritis can ease their pain.


Unprocessed olives are not bad for cats. The ones you can by in a supermarket come normally in packages containing a salty liquid. Salt contains sodium. Sodium can harm cats.

Common symptoms can occur as:

  • Vomiting
  •  Diarrhea
  • Extreme thirst
  • Excessive urination
  • A loss of appetite
  • Trenors
  • Seizures (if not treated might lead to kidney failure and death in the worst case scenario).

My recommendation is if you, after giving your furry friend an olive as a treat, recognize the one or other symptom, rush to the vet.

Please, do not forget to take out the olive seed to avoid your cat choking on it.

Cats seem to love the taste of the olive. It also has some medical benefits as of inflammatory and cancer decrease and reducing pain when they suffer arthritis.

So, my recommendation is to give cats olives on a more frequent basis.
