A guinea pig is eating small piece of grape.

There are several reasons why the guinea pig (cavy) belongs to one of the most popular pets in the world. Why? Because the guinea pig is hardy, easy to care for, lives longer, and is unique.

As a seasoned owner of multiple guinea pigs, I would say that guinea pigs love to eat grapes the same way you and I would love to eat grapes. Grapes are sweet, juicy, and are pretty attractive to guinea pigs. And when guinea pigs gobble up grapes, the grape juices usually get splattered all over their beards and whiskers, making them look even cuter. But is it healthy to feed your guinea pigs with grapes? You will learn the answers to this question as you read on. 

Should Grapes Be Included in the Daily Diet of Guinea Pigs?

Grapes are addictive. If you bloat your guinea pig pets with lots of grapes, they may end up with too much sugar in their systems, leading to obesity. Grapes come with higher sugar content. So, you better refrain from turning your guinea pig into grape addicts. Just let them eat grapes as an occasional treat. 

Moreover, it will be best to feed them with seedless grapes, for they may accidentally ingest the seeds. Likewise, it will be best to keep your cavies from luxuriating in the sugary grapes for their own sake to keep them healthy.

Besides, before feeding your cavies with grapes, it will be best to ensure that you rinse the grapes with water to do away with the bacteria and chemicals that come with the grapes. Furthermore, you should remove the stalks when you feed your guinea pigs with grapes. 

As a rule, you should only feed the cavies with any fruit like grapes on an occasional basis. Besides, grapes should not always be a part of their daily diet, nor should they be the day’s main dish.

Are Grapes Healthy for Guinea Pigs?

Grapes are healthy for most animals. But you would be surprised that not all pets benefit from grapes. The reason for this is because grapes can be toxic to some animals. Grapes, for example, can be harmful to dogs. Nevertheless, grapes are safe for cavies, and you can feed them occasionally with grapes. Yet, you may be asking if grapes are healthy for your cute guinea pigs. Yes, grapes can be beneficial to your guinea pigs, for grapes come with many micronutrients. 

A thorough evaluation of the nutrients of grapes shows that for 150 grams of grapes, your pet will get 1.09 grams of protein, 0.54 milligrams of potassium, and 15 milligrams of useful calcium. Other micronutrients your guinea pigs will get from a 150-gram dish of grapes include the following:

It will be best to remember that you should not give 150 grams of grapes to your guinea pig, for you will surely bloat your guinea pig. However, if you are bent on feeding your guinea pig with grapes, it will help to know the best ways to provide your guinea pig with grapes.

Vitamins and Trace Elements that Your Guinea Pig will Need

Grapes are rich in micronutrients, and you will find trace elements like magnesium, phosphorous, iron in grapes. These trace elements can be beneficial to your guinea pig. Yet, it can also be fatal to your guinea pig when given in large doses. Your pet only needs a trace of these elements, and for this reason, they are called “trace elements.” 

Iron, for example, is necessary to enable oxygen to move onto the different parts of the guinea pig’s body, including the brain. Lack of iron may lead to iron deficiency. There are other trace elements and vitamins present in grapes, and it will be best to know these vitamins and trace elements:

Vitamin C

Vitamin C is beneficial to the human body as well as to the body of your guinea pig. It is a powerful antioxidant. Vitamin C, of course, strengthens your guinea pig’s immune system, protecting it from viruses and bacteria, and if your guinea pig lives outside your house, it may be susceptible to these viruses. 

Vitamin C also occasions the intense production of serotonin, a hormone responsible for happiness. With enough Serotonin, your pet will be lively and in a good mood more often. 

Vitamin C also increases the production of nitric oxide and testosterone. Testosterone enables your guinea pig to be energetic, while nitric oxide is valuable for its vasodilation capability. It relaxes the blood vessels’ muscles, causing them to expand and increase blood circulation.


Magnesium comes in handy for building strong bones. With strong bones, your guinea pig will not get easily injured. Moreover, magnesium is known to enhance mood. It also encourages learning and improves sleep. Plus, magnesium relaxes the muscles and enables you to reduce anxiety. Lastly, magnesium also raises the level of testosterone. 


Another element that is helpful to your guinea pig’s overall health is calcium. Calcium helps your guinea pig build strong bones and complements the work of magnesium. It also helps in building stronger muscles. So, if you continuously supply your guinea pig with calcium, you can ensure that its muscles and bones will not atrophy quickly.


Iron is known for its presence in the blood cells. Oxygen needs iron to move around the body. With less oxygen in the different body cells of your pet, its body cells would not be healthy. So, your pet will need iron to help your guinea pig oxygenates its cells.


Another antioxidant molecule present in grapes is resveratrol. Resveratrol has been often discussed recently because of its link to the popular Mediterranean Diet that seems to be very healthy and responsible for longevity. You will find resveratrol in red grapes. It is responsible for the increase of mitochondrial efficiency. 

If you recall your biology class, you will remember that the mitochondria are considered the cellular energy factories, converting sugar to ATP. With the resveratrol in the cell, your guinea pig will have more energy and a longer lifespan.

Why Should You Monitor Your Guinea Pig’s Diet?

As a responsible pet owner, you should check your pet’s diet. This is essential because your pet is part of your family. Hence, you should ensure that you monitor your guinea pig’s diet. Your guinea pig will indeed become active, happy, and healthy if you regularly monitor their diet. 

Guinea pigs, of course, are widely studied animals. Moreover, a lot of scientific experiments were conducted on guinea pigs for the benefit of human beings. So, if you search online, you will discover tons of information about how to take care of guinea pigs. 

Their diets, however, necessitate certain ingredients to ensure that they function well. It is not enough to provide your guinea pig with the same diet that you eat, for we usually eat processed food. So, this food will never be healthy for your guinea pig pet. 

If you feed your guinea pig with the same diet that you eat, chances are your pet will become obese because most of the beneficial nutrients are already gone from the processed food. Hence, if you are a responsible pet owner, you should ensure that you feed your guinea pig with a nutritious meal.
