Because, peanuts butter is high in calories, carbohydrates, fat, and salt and the digestive systems of guinea pigs can’t handle them.

Certain researchers say that guinea pigs cannot eat nuts of all types and varieties, peanut butter and other nuts are essentially an extension of this.

Nutrition Constitution of Peanuts Butter

Peanut butter is a food paste or spread made from dry roasted ground peanuts.

It often contains additional ingredients that modify the taste or texture, such as salt, sweeteners etc.

Though peanut butter is suitable for humans, but not for guinea pigs even as a treat.

Peanut butter consists of ground peanuts, so it’s rich in vitamins and nutrition.

It contains :


There are approximately 294 calories in 50 grams of peanut butter.

This may seem like large serving.

If you regularly feed peanut butter to your dear pet you would be dramatically increasing the number of calories they consume, as a result of which, they will gain a lot of weight.

Extra weight is very problematic for your guinea pigs for many reasons.

Carbohydrates and sugar

In 50 gram peanut butter there is 9.78g carbohydrates, 4.5g of which comes from sugar.

While this can provide humans with energy but it’s too much for a guinea pig to consume and handle.

This extremely high amount of sugar content can upset their stomach.


Protein is also high in peanut butter, it’s around 12.5 gram in 50 gram of peanut butter.

Again, it’s not good for guinea pig.


There is 25.2 gram of fat in 50 gram of peanut butter.

So it is predominantly made up of fat.

Many peanut butter brands also add extra fat for taste, flavor and texture.

Guinea pigs cannot handle so much fat in their diet and it’s not good for their digestive system because this can lead to dehydration and diarrhea.


Peanut butter has salt and we know that too much salt in the diet of guinea pig is not good and it can lead to negative health outcomes including bladder and kidney stones.

So you would do best to avoid feeding salt to your guinea pig.

Even though guinea pigs might be able to swallow peanuts butter, but their digestive system/tracts isn’t designed to accommodate all the fats peanuts butter has.

It often contains added sugar and other ingredients that aren’t good for your pet.

The sticky texture of peanut butter can cause trouble for your guinea pig as well.

The nutritional content of peanuts butter doesn’t provide any health related benefits for your pet except the sheer taste of it or some vitamin.

Perhaps, guinea pigs like the taste of peanut butter.

But it is not beneficial for your pet health.

There are so many risks of feeding peanut butter to guinea pigs.

Before feeding peanuts butter keep these risks in your mind.


There is risk of allergy if you feed peanuts butter to your guinea pig.

That is why you need to observe your pet after you give him something new to eat.

Not suited for them

Peanut butter is made from peanuts and peanuts are just not suited for them because of the high amounts of fat present, these fats can make guinea pig develop certain diseases.

The high amount of salt and sugar is also not suited for them.

Obesity or Risk of gaining weight

Peanut butter is very caloric.

It is a spread, so it is even easier to consume.

For guinea pigs, this increases their chances of gaining weight – both in the short realm of time and also in the long period.

The high fat content will also likely deposit around organs, block blood vessels, and generally make your guinea pig more lethargic and fatigued.

Obesity is bad for their life, because they can’t handle too much fat.

Digestive Issues

Guinea pigs have delicate digestive system.

Peanut butter can cause a lot of digestive problems and this is all due to the three components it contains – fibers, fats and sugars.

While fiber should always high in a guinea pigs’ diet, it should come through hay and other vegetables.

This is because guinea pigs require both digestible and indigestible fiber yet peanut butter only provides one of these.

This imbalance can lead to loose stools, gas, and stomach pain which is fatal.

Secondly, fat in peanut butter is of significant amount.

This is a lot for your guinea pig to process, especially because they are not used to it and their digestive system was not designed to process it to begin with.

Finally, sugar is known to disrupt a guinea pig’s digestive system and peanut butter contains a lot more than you would think.

Urinary Issues

Peanut butter contains calcium.

Calcium intake should always be carefully managed and regulated as it can lead to a lot of serious health implications in elder guinea pigs.

While it’s put to use while your guinea pig is a pup, in their elder years it builds up within their urinary tract.

This can lead to painful and problematic bladder and kidney stones, urinary infections, pain during urination and sometimes blood in the urine.

This requires treatment and if left diagnosed can result in renal failure.
