Did you know that, according to claims, there are between 100 and 700 species of squash, mostly categorized into winter and summer type squashes? Can guinea pigs eat squash? Which types of squash a guinea pig can eat? Is squash beneficial to these small animals? Let’s answer these questions.

Guinea pigs can eat squash but only in moderation. This vegetable contains beneficial antioxidants but also contains less sugar compared to sweet potatoes. Also, squash contains magnesium, calcium, iron, vitamin A, vitamin B6, and vitamin C.

Squash is probably one of the easiest crops you can grow in your garden and one of the tastiest meals you can cook.

Other varieties of summer squash, like zucchini, are safe for your guinea pig to eat if cut into small pieces and served raw.

Can Guinea Pigs Eat Squash?

squash cut in halfAs you already know, the main source of fiber in a guinea pig’s diet is timothy hay. Guinea pigs need fresh and raw fruits and vegetables to obtain other important nutrients, vitamins, and minerals.

One of the most important nutrients in a guinea pig’s diet is vitamin C because these small animals cannot synthesize it on their own.

Vitamin C deficiency leads to scurvy, which is a potentially fatal disease in guinea pigs. Although squash contains vitamin C, guinea pigs can have squash but only in moderation.

What is Squash?

The word squash is from the local American word “askutasquash” which means “eaten crude” or “uncooked.”

Just like tomatoes (you can learn more about that here), squash is a fruit that has over 100 varieties (such as acorn squash, banana squash, buttercup squash, butternut squash, spaghetti squash, etc.).

Yes, we cook it, bake it, etc. as if it were a vegetable.

However, never feed your guinea pig cooked or baked squash.

A guinea pig can digest only fresh and raw fruits and vegetables.

All types of squash are tasty and sweet for piggies.

Moreover, they are high in nutrients but the amount of vitamin C in squash doesn’t meet a guinea pig’s daily requirements.

Piggies need between 30 and 50 mg of vitamin C every day.

Winter squash matures late. Some popular winter squash types include butternut, acorn, spaghetti, buttercup, and Hubbard squash. Winter squashes have a hard, thick rind, and thick orange or yellow flesh. They are less symmetrical and even completely irregularly shaped. Their thick skin allows us to keep them for months in a dry, cool place.

Summer squash sorts are smaller compared to winter squashes. They also grow faster. We consume them when the fruit is still immature before the seeds and rinds harden. Yellow squash, zucchini, and pattypan, also known as scallop squash, are among the most common varieties of summer squash.

Both summer and winter squashes have edible skins, seeds, and blossoms.

Why Should Guinea Pigs Eat Squash?

The key to a healthy guinea pig diet is moderation and balance.

For instance, a grownup guinea pig shouldn’t consume foods rich in calcium because it accumulates in their bodies and could lead to urinary problems, and kidney and bladder stones.

Squash is high in vitamin C, vitamin A, and other minerals and vitamins that boost your guinea pig’s health and growth.

However, the balance of all these nutrients in squash is not ideal for guinea pigs.

So yes, your guinea pig can have squash but only occasionally and in limited quantities.

What Are the Benefits of Feeding Guinea Pigs with Squash?

Prevents Scurvy

Squash contains vitamin C, which prevents scurvy, a lethal illness that presents itself with a rough coat, fatigue, loss of appetite, bleedings, peculiar releases, and diarrhea.

However, the amount of vitamin C in squash is not high enough for your piggy’s daily needs.

Maintains Health

Squash contains vitamin K, iron, and copper which guarantee healthy blood. It helps build immunity and thereby helps reduces the risk of anemia.

Many guinea pigs love squash!

Healthy Digestion

The fiber in squash is essential for your guinea pig’s healthy digestion. This is another reason why feeding your guinea pig with squash is a great idea.


The many minerals and nutrients in butternut squash work as cell reinforcements, curb free radical damage, and boost immunity.

These antioxidants will keep your guinea pig healthier for longer so your pet pig is less likely to fall sick or suffer from serious infections.

Weight Management

Squash contains protein, carbs, and fiber. Furthermore, it’s low in fat and has a sweet taste that guinea pigs like.

Thus, it’s a great idea to feed your guinea pig with squash. Besides, the proteins and sugars give your guinea pig the energy to stay active.

To understand squash and its varieties better, let’s look at one of each type in detail.

Can Guinea Pigs Eat Butternut Squash?

Yes, guinea pigs can eat butternut squash.

It is a yellow squash or orange-fleshed winter squash, celebrated for its adaptability and sweet, nutty flavor that guinea pigs like.

It feels like pumpkin in texture and taste, and guinea pigs love it.

It grows on a plant close to the ground with a bulbous base half and an elongated top.

Although some people think that guinea pigs can eat the skin, the inner fruit, and the seeds of butternut squash, we recommend removing the seeds by scooping them out.

Seeds of all kinds represent a choking hazard for guinea pigs.

Advantages of Butternut Squash

  • Contains vitamin C, which is the most important for a guinea pig as it helps a guinea pig use protein and battle diseases
  • It contains common proteins and starches, giving your guinea pig a quick and moderate wellspring of energy during the day
  • Butternut squash additionally has fiber that is fundamental for healthy digestion
  • The risk of heart conditions and hypertension is diminished as it doesn’t contain any cholesterol
  • It additionally has vitamin E and K for great immunity, healthy skin and bones
  • Magnesium and iron for muscles, a solid heart, and healthy blood.
  • Vitamin A likewise adds to a solid healthy immune system

How Much Squash Should I Give My Guinea Pigs to Eat?

It’s very important to take note of the serving size when feeding your guinea pig with butternut squash.

Wash it well to eliminate any compost, pesticide, or synthetic compounds that may have been on it.

Depending on your guinea pig’s preference, you can choose to leave the skin on or strip it off.

Cut them into small cube sizes and only give your guinea pig the meaty part.

Never feed your guinea pig with the seeds, stem, or stalk.

A guinea pig shouldn’t eat butternut squash more than 2-4 times per week.


Although butternut squash has plenty of supplements, minerals, and nutrients that your guinea pig pet needs, there are a few reasons why squash isn’t beneficial for these small animals.

If they are fed with too much squash, it can cause two big health problems in guinea pigs:

  • Urinary issues
  • Stomach discomfort

Urinary Issues

Butternut squash has both calcium and phosphorus for healthy bones. However, excessive calcium gets stuck in the urinary tract creating stones in the kidneys or the bladder.

This makes for excruciating peeing and if not treated, could prompt renal failure and possible death.

Stomach Discomfort

Butternut squash contains oxalic acid, which can damage a guinea pig’s sensitive stomach.

The seeds are a stifling danger, so ensure you scoop them full scale first.

Can Guinea Pigs Eat Zucchini Squash?

many unprepared, unpeeled zucchinisZucchini, otherwise called courgette, is another summer squash in the Cucurbitaceae plant family, alongside melons, spaghetti squash, and cucumbers.

It can grow to over 3.2 feet (1 meter) long. However, it’s generally reaped when still immature, less than 8 inches (20 cm).

Although zucchini is regularly viewed as a vegetable, botanically it is also a fruit.

The color of this type of squash varies from intense yellow to dull green.

All color varieties of zucchini are summer squash meals that are very healthy both for humans and for guinea piggies.

Advantages of Zucchini

  • Zucchini contains a large amount of vitamin A which assists with supporting the vision and strengthening the immune system
  • It has antioxidants, otherwise known as cell reinforcements, that help to shield the body from the impacts of free radicals which cause degenerative illnesses
  • Squash zucchini has a good measure of fiber that helps with digestion and in some cases balances out the glucose levels
  • It gives about a similar measure of vitamin C as winter types of squash, which makes it perfect for combating scurvy

Serving Size

When serving zucchini, start by cleaning them well to eliminate microscopic organisms, pesticides, and different synthetic substances that might be hurtful.

Next, cut off and dispose of the thick stem. There is no reason to strip off zucchini. You can leave the skin since it’s tender and your guinea pig can eat it.

Cut the zucchini into little scaled-down-solid shapes. You might need to eliminate the seeds.

Feed your guinea pig with about 2 small bite-sized pieces per offering.

Zucchini is safe for your guinea pig and most piggies like it.

Eliminate leftovers promptly after serving to forestall microbes shaping on them.

Dangers of Feeding Zucchini to Guinea Pigs

  • A high calcium diet can prompt urinary problems such as bladder stones
  • An excessive amount of zucchini can prompt stomach-related illnesses
  • There is a poison, cucurbitacin, that zucchinis produce normally, which is unpleasant in taste
  • Cucurbitacin can be toxic to guinea pigs and cause runs, heaving, or passing


  • Zucchini is a vegetable that contains a ton of nutrients and minerals fundamental for piggies
  • A guinea pig can eat zucchinis regularly as long as we serve them in the right quantity
  • Only two to three bite-size cubes of zucchini, when combined with other healthy guinea pig food in the form of fruits and vegetables, is sufficient for your guinea pig’s daily needs
  • A guinea pig can eat zucchini with its skin and seed; yet you should ensure it’s free from poisonous synthetics
  • If you feed your guinea pig with an excessive amount of zucchini, it can be fatal
  • Small-sized zucchinis generally have a higher supplement incentive than a normal-sized one, which is a good choice for piggies
  • Make sure you introduce zucchini into your guinea pig’s diet very slowly. Any drastic change in their diet could lead to a -disbalance in their sensitive digestive system, which can be fatal in some cases.

Can Guinea Pigs Eat Yellow Squash?

Yellow squash is another type of summer squash that your guinea pig can eat. Rich in vitamin C, yellow squash is a super-tasty veggie used in many recipes.

This vegetable is beneficial because it contains lots of vitamin C and vitamin A.

Regardless of how sweet or good yellow squash is you should give it to your guinea pig in moderation.

This will ensure a balanced diet for your pet.

Health Benefits of Yellow Squash

many unprepared, unpeeled yellow squashesThe summer yellow squash taste is delicious, mildly sweet, and even a bit nutty. But what are the exact benefits of feeding guinea pigs yellow squash?


Yellow squash is low in calories, carbs, proteins, and fat, which prevents rapid weight gain of piggies.

Healthy guinea pig food is low in these elements, as well as in calcium that’s responsible for the development of bladder stones.


Yellow squash contains vitamin A which is an amazing antioxidant as it helps fight the free radicals and the damage they cause.

The result is that your guinea pig receives a boosted immune system and becomes healthier. Nonetheless, despite all the health benefits, give squash to your guinea pig in moderation.

Scurvy Prevention

Yellow squash contains vitamin C so it prevents vitamin C deficiency (scurvy).

Serving Size

Two to three bite-size cubes two to three times per week is enough for piggies.

Hazards of Feeding Guinea Pigs Yellow Squash

Urinary Problems

Calcium in yellow squash is a health risk for guinea pigs.

When this mineral is consumed in large amounts, it can cause damage to the urinary tract.

Digestion Problems

If eaten in large amounts, squash can cause some minor digestion problems.

This veggie contains sugars and fibers. Guinea pigs like sweet foods but if they consume food high in sugar, symptoms such as painful digestion, gasses, cramps, and loose stool could appear.

Yellow Squash Facts

  • The yellow squash has a thin skin that can also be consumed
  • It’s related to melons and watermelons
  • The yellow squash is harvested immature and not ripe while the rind is still edible and tender

Final Thoughts

Both summer squash and winter squash have varieties and all are safe for your pet guinea pig.

Although this fruit is quite nutritious, the balance of nutrients is not safe for guinea pigs to eat daily.

Apart from timothy hay, your pets need one cup of vitamins and minerals obtained from raw and fresh fruits and vegetables.

Feed your guinea pig squash a few times per week and in small, bite-sized pieces.

This amount of squash is perfectly beneficial and safe for your guinea pig pet.

Make sure the vegetables are fresh, thoroughly cleaned, carefully prepared, and never cooked or processed in any way. Also, to be on the safe side, eliminate all the seeds that present a choking hazard to your guinea pig.
