Can guinea pigs eat zucchini?

This is something that must have been troubled you more than once, especially if you own a guinea pig as a pet and you’re a lover of zucchini.

Zucchini is a popular plant found in the summer during the season of cucumber and melons.

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

Anyway, a guinea pig’s diet is a complex matter.

Although the main source of fiber is timothy hay, guinea pigs also eat fresh fruits and vegetables, but not all are safe for guinea pigs to eat.

While cats and dogs eat nearly everything a human being would, many sensitive pets such as guinea pigs need general research on their diet.

So, if you’ve ever asked the question, “can guinea pigs eat zucchini?”, sit back as we’ll answer the question right away!

Can Guinea Pigs Eat Zucchini?

If you want to know whether guinea pigs can eat zucchini, yes, guinea pigs can eat zucchini.

You should know that zucchini is healthy for guinea pigs.

The fruit contains a reasonable amount of vitamin C; thus, you should include it in your guinea pigs’ daily diet.

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

Some guinea pigs enjoy eating peeled zucchini, while some love eating it with their skin.

Just as human beings, guinea pigs are quite fussy when it comes to vegetables and fruits.

Guinea pigs have a delicate digestive system and cannot munch on everything like human beings.

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’s diet.

What Are The Health Benefits of Eating Zucchini?

Zucchini is an exceptional source of vitamin C, so you can serve zucchini to your guinea pig knowing that it will get enough vitamin C.

Guinea pigs require vitamin C and their bodies cannot make it on their own.

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 overall proper digestion)
  • Have antioxidant properties (Antioxidants in zucchini (lutein, zeaxanthin, and beta-carotene) and in 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 pet, 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 has little in calories, which brings satiety and reduces the intake of other foods.

What Is the Nutritional Value of Zucchini?

Zucchini is a great plant that most guinea pigs like to eat.

It’s not a single-nutrient vegetable but contains several other essential nutrients.

Zucchini is 90% water; therefore, it’s good for the hydration of your pet.

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 guinea pigs.

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

Although this is not a considerable amount, it’s also a moderate one.

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.

Vitamin C in zucchini is very convenient since the portions you feed your guinea pig should be around 100 grams, meaning they are getting 18 mg from the zucchini.

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

Serving zucchini in excess may trigger some health complications.


Phosphorus is an essential element that plays a vital role in keeping your pet 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, especially when your pets grow older.

It also plays a substantial role in helping different body organs and 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, you should therefore not worry about your pet getting excess at once.


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

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 pet 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 accountable 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 with zucchini and watch their body reactions.

When you notice any white residue in their urine, this can indicate too much calcium.

Too much calcium can result in kidney stones, a condition peculiar to human beings.

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 through 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 manufacture this vitamin in their bodies; therefore, you must ensure you get enough 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.

How To Serve Zucchini to My Guinea Pig?

There are many risk factors to consider when feeding zucchini to your guinea pigs.

Guinea pigs like eating zucchinis, so the first thing you should do before serving it to your pet is to wash it thoroughly.

Vast volumes of zucchini can cause vomiting and diarrhea in guinea pigs.

At some point, it can cause the accumulation of excess gases in their stomachs.

Another problem associated with zucchini in pigs is toxicity.

Zucchinis naturally produce cucurbitacin toxin hence becoming bitter.

Cucurbitacin is very poisonous to 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.

Any bitter zucchini should not be given to the guinea pigs or eaten as well.

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

The bitter the zucchini, the higher the amount of cucurbitacin.

Crucial Facts About Zucchini

However, 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 pig’s health.

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