A healthy guinea pigs diet consists of unlimited amounts of timothy hay and fresh fruits and vegetables. Yet, guinea pigs cannot eat all the food that human beings can as not all are safe for guinea pigs to eat. Let’s find out whether guinea pigs can eat zucchini, how much they can eat, and what are the benefits of feeding your guinea pigs zucchini.

Guinea pigs can eat zucchini frequently because they are low in calories, fat, and sugar but are also a great source of folates, a variety of vitamins (vitamin C, vitamin A, vitamin B6), and minerals (iron, copper, magnesium, etc.), and other beneficial plant compounds.

Although botanically categorized as a fruit, many people believe that zucchini is a vegetable.

Zucchini is a type of summer squash and is a part of the Cucurbitaceae family, a group of plants that includes cucumbers, pumpkins, melons, and watermelons.

A guinea pig’s diet is a complex matter.  Guinea pigs need a moderate and balanced diet that consists of timothy hay and fresh fruits and vegetables.

Can Guinea Pigs Eat Zucchini?

many unprepared, unpeeled zucchinisGuinea pigs can eat zucchini. It is healthy enough for guinea pigs so they can consume it every day.

The fruit contains a reasonable amount of vitamin C and vitamin A.

When feeding your guinea pigs zucchini, ensure it’s in moderation to avoid health complications that may eventually arise.

Just as human beings, guinea pigs are quite fussy when it comes to vegetables and fruits. Some guinea pigs enjoy eating peeled zucchini, while some love eating it with their skin.

Guinea pigs have a delicate digestive system and cannot munch on everything. Some vegetables can be suitable for them, whereas others may not.

Nevertheless, yes, guinea pigs love to eat zucchinis and fresh zucchini is the best option for your pet guinea pig.

Are Zucchinis Fruits or Vegetables?

Zucchinis are botanically classified as fruits, just like cucumbers or tomatoes but are used as vegetables. They can be cooked, fried, and baked.

Zucchinis grow from the zucchini flower, and this explains why they are categorized as berries.

According to scientific definition, a vegetable is any edible part of a plant, either root or leaves. Since zucchinis come after the flowering stage, they are fruits.

The Smaller the Fruit, the Better

Also, the darker the zucchini skin, the higher the nutrients in the fruit.

The Leaves

Zucchini leaves are just like any other leafy greens that guinea pigs can eat.

But don’t overfeed your guinea pigs zucchini leaves. These small animals require variety, so don’t continuously give them the same food.

What Are The Health Benefits of Eating Zucchini?

Zucchini is a good source of vitamin C, which is an essential vitamin for these small animals.

Guinea pigs require vitamin C and their bodies cannot make it on their own. Vitamin C deficiency leads to scurvy, which is a life-threatening illness in guinea pigs.

The nutrients in zucchini:

  • Prevent scurvy (Scurvy is a hazardous condition and potentially fatal that is visible in a guinea pig’s lack of energy, loss of appetite, weight loss, inability to heal fast, and digestive issues)
  • Aid digestion (Fibers are perfect for a healthy digestive system of your guinea pig)
  • Have antioxidant properties (Antioxidants in zucchini (lutein, zeaxanthin, and beta-carotene), and its skin counter the free radicals in the body of a guinea pig)
  • Add health to the bones (Magnesium and vitamin K are both found in zucchini and they play significant roles to ensure healthy bones)
  • Improve sight and vision ( Antioxidants, vitamin C, beta-carotene, lutein, and zeaxanthin, assist in developing the sight and vision of your guinea pig, fill the retina and improve eyesight.)
  • Help in losing weight

Always have in mind that zucchini skin contains many antioxidants so you shouldn’t peel off the skin.

Despite this, only some guinea pigs like eating the outer skin of zucchini.

Courgette has lots of water and is low in calories, which brings satiety and reduces the intake of other foods.

What Is the Nutritional Value of Zucchini?

Zucchini is a great fruit, a type of summer squash that most guinea pigs like to eat.

Although zucchini contains about 90% water, it contains many nutrients beneficial for the health of your guinea pig.

The high water content is always accompanied by low calories and a low level of fats.

For guinea pigs, which are prone to obesity, zucchini is a great way to acquire lots of nutrients without serving your pet foods that contain too much sugar and many calories.

So, yes, guinea pigs should eat zucchini although in moderation.

Vitamin C

As mentioned above, vitamin C is essential for the proper functioning of a guinea pig’s body and immune system.

The amount of vitamin C in 100g of zucchini is high (about 18 mg).

Guinea pigs require about 30 to 50 mg of vitamin C, while pregnant sows will need more.

They are allowed to eat nearly all fruits and vegetables that contain vitamin C.

Although they can eat zucchini daily, it is recommended that a daily portion should not exceed 100 grams.

Serving zucchini in excess may trigger health complications.


Phosphorus is an essential element that plays a vital role in keeping your guinea pig in good health.

The primary role of phosphorus is the formation of strong, healthy bones and teeth.

However, phosphorus also affects how the body utilizes fats and carbohydrates and is also a necessity in producing proteins, which are responsible for the growth and restoration of different cells of the body.

In conjunction with the B vitamins, phosphorus helps in keeping the kidney healthy and functional.

Zucchini is a rich source of nearly all other elements except sodium.

Serving zucchini to your guinea pig is a great idea because of the different nutrients in one serving.

Vitamin A

Vitamin A is essential for your guinea pig’s eyes and skin, which is important as your guinea pig grows older.

It also plays a substantial role in the healthy response of the immune system.

However, vitamin A should be taken moderately, and when taken in excess, it can pose health risks.

But since zucchini contains just a little amount, enough to maintain the health of your guinea pig.


Just like phosphorus, magnesium, and calcium, potassium is one of the essential minerals for guinea pigs.

Zucchini contains more potassium than a banana, which is the known fruit with the highest potassium level.

These minerals balance themselves out when it comes to guinea pigs.

There are recommended ratio intakes.

If the ratios are not entirely represented, extra minerals will be removed through the urine.

Potassium mineral helps in lowering blood pressure and the risk of contracting heart complications.

Low Calories, Sugar-Free

Although zucchini contains many essential nutrients, it is low in sugar and fat.

Guinea pigs are prone to obesity; therefore, excess sugar is not suitable for their health.

Zucchini is the perfect way to provide your guinea pig with much essential nutrition without added sugar and calories.


Calcium is an essential mineral for the general health of a guinea pig.

Calcium is responsible for healthy teeth and bones.

It also helps in keeping the balance between magnesium and phosphorus. Calcium is also responsible for vitamin absorption.

Guinea pigs belong to the group of animals that cannot control their calcium intake. No matter how much calcium they have absorbed, their digestive systems will continue to absorb as much calcium as possible.

So, always be on the lookout when feeding your pets zucchini.

Too much calcium can result in kidney stones, which can be fatal for guinea pigs, especially male piggies.

Anytime you feel that your guinea pig requires medical attention, don’t hesitate to visit a vet.

Dietary Fiber

Dietary fiber is on the skin of zucchini.

It has excellent benefits as it aids digestion and prevents heart-related diseases.

The fibers are also necessary for a healthy heart by regulating the amounts of excess cholesterol in guinea pigs.

Vitamin B6

Vitamin B6 is significant for the health of your guinea pig regardless of their age or size.

Guinea pigs do not produce this vitamin in their bodies but have to get it through food.

For the production of red blood cells and hemoglobin, vitamin B6, and other crucial elements such as fats, proteins, and carbohydrates are essential for body functions.

Zucchini is a good source of Vitamin B6 and thus should be included in your pet’s diet.

Is Zucchini Bad for Guinea Pigs?

If you feed your guinea pig excess zucchini, it may result in the development of kidney and bladder stones due to the accumulation of calcium.

Although calcium is necessary for guinea pigs, feeding your guinea pig food that’s high in calcium can create health problems.

Feeding guinea pigs zucchini can also result in stomach problems such as bloating, vomiting, and diarrhea.

Zucchinis naturally produce cucurbitacin, which is a substance found in pumpkins, gourds, and cucumbers (which all belong to the family Cucurbitaceae).

Cucurbitacin is very poisonous, especially for small animals such as guinea pigs, and can result in nausea, diarrhea, or death.

Feed your guinea pig only fresh zucchini, and the one you have tried and tested before to ascertain it works pretty well for your little friend.

You should never feed your guinea pigs bitter zucchini.

Cucurbitacin toxin is also harmful to human beings and can even result in death.

How Often Should My Guinea Pig Eat Zucchini?

At this point, you already know that it is safe for your guinea pig to eat zucchini, even with all the dangers.

Feeding guinea pigs this type of summer squash is not hard.

You simply have to wash the zucchini, but you don’t have to peel it. Cut it into small bite-size cubes and serve it to your pet.

Guinea pigs can eat zucchini daily, but it is recommended that you feed them about 100g of zucchini 3 to 4 times per week.

Despite the many health benefits that your guinea pig can get from zucchini (vitamin C and antioxidants above all), you should be careful.

Zucchini is not very high in calcium but adding this summer squash to your pet’s diet daily can disrupt its sensitive digestive system.

What is the Serving Size of Zucchini for Guinea Pigs?

Knowing the amount of zucchini to feed your guinea pig is very important.

The standard serving size should be a handful or around 1 cup.

This amount is enough for them since they are small animals; hence don’t overfeed them.

You also have in mind that vast amounts of zucchini can lead to excess gases, vomiting, or diarrhea.

Can My Guinea Pigs Eat Raw Zucchini?

You can feed your guinea pigs raw zucchini, and the only way to serve zucchini is to do it raw.

Guinea pigs eat zucchini only raw as they cannot digest processed food.

Never feed your pets with cooked zucchini since they cannot eat any cooked food as their digestive systems only digest raw and fresh food.

Providing your guinea pig with only fresh and raw zucchini is very important.

It would be best if you feed your guinea pig with zucchinis without pesticides and any other chemicals.

Is Green Zucchini Good for Guinea Pigs?

Green zucchini is very good for your guinea pig.

Green zucchini is the widely known type of zucchini, and many people who rear guinea pigs have confirmed that their guinea pigs eat green zucchinis more than they do yellow ones.

many unprepared, unpeeled yellow zucchinisHowever, yellow zucchinis are sweeter than green ones, and guinea pigs can eat them as well.

Even though guinea pigs feed more on green zucchinis than their yellow counterparts, the yellow zucchinis also are rich in nutrients that are beneficial to guinea pigs’ health.

Because yellow zucchinis are sweeter, you shouldn’t let your guinea pigs eat zucchini often.

The best option is to feed them with a mixture of both in small amounts a few times per week.

Can Guinea Pigs Eat Zucchini Flowers?

There is no harm to guinea pigs feeding on zucchini flowers since the flowers have lots of nutrients like beta carotene antioxidants and vitamin C, suitable for their health.

Yes, guinea pigs will enjoy feasting on zucchini leaves because of their soft texture.

Just ensure you wash the leaves before serving your guinea pigs to get rid of any possible dust, insects, or pesticides which can harm your guinea pig.

Please serve them the zucchini flower’s petals and eliminate the inner parts since guinea pigs are sensitive to pollen grains.

Only give them fresh zucchini flowers, and if you are serving them flowers for the first time, keenly monitor their behaviors and reactions to know if they respond well to zucchini.

Can Guinea Pigs Eat Zucchini Leaves?

Zucchini leaves are edible even by human beings; therefore, guinea pigs safely eat zucchini leaves if you feed in control.

It is advisable to feed guinea pigs with zucchini leaves utmost twice a week.

They should also be served in small amounts since massive amounts may cause stomach complications and diarrhea in guinea pigs.

While feeding your guinea pigs on zucchini leaves, always consider young leaves and avoid older leaves since they are still bitter and have high amounts of cucurbitacin, which is very poisonous for guinea pigs.

Can Guinea Pigs Eat Zucchini Skin?

It is entirely safe to feed your guinea pigs on zucchini peels.

The peels are rich in many nutrients that are good for guinea pigs’ health, just like most of the antioxidants are on the zucchini skin.

However, some guinea pigs may avoid eating the peels since they don’t like it, which is normal, so never force your pet to take something they don’t like.

The skin is essential to your guinea pig since they contain a reasonable amount of fiber suitable for a guinea pig’s digestive system.

Before serving peels, wash them thoroughly to eliminate any possible pesticide contents.

Are Zucchini Seeds Safe for Guinea Pigs?

Zucchini seeds are safe for your guinea pigs’ consumption.

Although they are small and soft, don’t give your guinea pigs seeds as they present a choking hazard.

When preparing zucchini for your guinea pigs, slice it into smaller pieces, and remove the more giant seeds to ensure that the seeds will not choke your guinea pig.

Is Zucchini Bread Safe for Guinea Pigs?

Guinea pigs should not be given zucchini bread since their digestive system are not modified to digest processed or cooked food.

Never feed your guinea pig with any form of bread or human food.

Guinea pigs have susceptible digestive systems, and zucchini bread can be harmful to them.

Since guinea pigs are herbivores, they enjoy eating fresh vegetables and raw fruits.

Giving them cooked or preserved food may interfere with their digestive systems, so they should never be a part of your guinea pig’s diet.

How To Serve Zucchini To a Guinea Pig?

There are many risk factors to consider when feeding zucchini to your furry friends.

Guinea pigs like eating zucchini.

You don’t have to peel the zucchini but the first thing you should do before serving it to your pet is to wash it thoroughly.

Another reason you should wash your food before serving is to eliminate soil particles and organisms that may have stuck on the skin.

After having washed the zucchini thoroughly, chop off the thick stem and cut it into small pieces to avoid the possibility of your guinea pig choking on food.

Final Thoughts

Your guinea pig’s diet rests on fiber from hay but other nutrients come from fresh and raw fruits and vegetables.

Frequently giving zucchini to guinea pigs to eat is a good idea because zucchini is low in calories, fat, and sugar but high in beneficial nutrients such as vitamin C, vitamin A, vitamin B6, and iron, copper, magnesium, etc.

The recommended serving size of zucchini is 100g 3 to 4 times per week.
