Can guinea pigs eat pumpkin, you might be wondering because these small animals are fickle eaters.

Pumpkin is one of the oldest and most nutritious fruits.

The vitamins, minerals, iron, carotene, calcium, carbohydrates, and other healthy diet nutrients of pumpkin are beneficial to your pet.

Can Guinea Pigs Eat Pumpkin?

To keep your pet healthy, you should know that guinea pigs can eat pumpkin but should not eat it more than twice a week in a moderate amount.

Most cavies like pumpkin and will gladly eat it.

Pumpkin treat is an excellent treat, but it can’t replace the daily guinea pig’s diet of fresh timothy hay.

That is because various properties of pumpkin can surpass or be insufficient for guinea pigs’ normal healthy diet.

For instance, the amount of vitamin C guinea pigs require is more than the total amount of vitamin C pumpkins have, and the amount of calcium guinea pigs need is far less than the amount of calcium in pumpkins.

Therefore, guinea pigs can eat pumpkin, but you should always offer it in a small amount because too much pumpkin is detrimental to them.

To know all the exact requirements of your guinea pig’s diet, we have to first learn more about pumpkins and what nutrients they contain.


Pumpkin, also known as winter squash, is a fruit of various cultivars (a hybrid of two species) of herbaceous plants (Cucurbita pepo, C.maxima, C.moschata, and C.mixtasynonym C.argyrosperma) of the gourd family that is typically round and orange but also might be another shape or color.

There are several varieties of pumpkins, including Jack-o’-lantern (mainly used for craving), giant pumpkin, miniature, white pumpkin, pie pumpkin, and others.

These fruits have rind or skin, seeds, leaves, stems, pulp, flesh, and flowers as main parts.

Pumpkins don’t have any harmful chemicals such as strong acids that can put us in danger if consumed.

Humans can eat all the above-mentioned parts of the pumpkin and get the maximum benefit out of its nutrients.

However, the question is whether a guinea pig can eat pumpkin parts without harmful effects on its health.

Let’s see what these nutrients are and whether they are safe for guinea pigs.

Pumpkin Nutrition Facts

Pumpkins are rich in nutrients and have many health benefits.

Vitamin A in pumpkins is a strong antioxidant that keeps the eyes, lungs, kidneys, and skin healthy.

They prevent disease and fight inflammation caused by free radicals damage, and give strong immunity and healthy life to a guinea pig.

Pumpkins have few amounts of protein and carbohydrates which allows guinea pigs to develop slow and quick energy release for their daily needs.

Pumpkins are rich in carotenoids, including alfa-carotene, beta-carotene, lutein, and zeaxanthin.

The beta-carotene in pumpkin prevents the deficiency of vitamin A (the strong antioxidant).

Carotenoids along with vitamin A and vitamin E can provide all the necessities of guinea pig’s eyes, as such; they can keep healthy eyesight.

Pumpkins have various kinds of nutrients that are needed to keep your guinea pig healthy.

Here’s what a 100 gram of pumpkin contains:


  • Vitamin A = 426µg
  • Vitamin B-6 = 0.061mg
  • Vitamin C = 9mg
  • Vitamin E = 1.06mg
  • Vitamin K = 1.1µg
  • Alfa carotene = 4016µg
  • Beta carotene = 3100µg
  • Folate = 16µg
  • Lutein + zeaxanthin = 1500µg
  • Niacin = 0.6mg
  • Pantothenic acid = 0.298mg
  • Riboflavin = 0.11mg
  • Thiamine = 0.05mg
  • Energy = 26kcal


  • Potassium = 340mg
  • Phosphorous = 44mg
  • Magnesium = 12mg
  • Calcium = 21mg
  • Manganese = 0.125mg
  • Sodium = 1mg
  • Iron = 0.8mg
  • Zinc = 0.32mg

Pumpkins contain water in high quantity (91.6g), and vitamin K is low in quantity (1.1µg).

All of the listed nutrients are 100% safe for guinea pigs.

However, the amount of sugar and calcium in pumpkin your pet eats should be minimal.

Besides, foods high in sugar will make your cavy eat too much and become obese.

This can also be balanced by following the right serving size and frequency or, occasionally, by mixing little pumpkin with other fruits and vegetables.

How Much Pumpkin Can Guinea Pigs Eat?

Guinea pig’s molars are suited for grinding plant matter and grow continuously throughout their life.

That’s why every guinea pig feeds on hay, herbs, fruits, and vegetables.

Naturally, young guinea pigs need vitamins and minerals to strengthen their bones and help them build energy.

So, the question is how much pumpkin guinea pigs can eat.

Here’s the answer: it’s healthy to give them up to 2-inch cubes of fresh pumpkin per week.

Adults shouldn’t eat more than 2 inches of pumpkin a week.

Excess sugar and calcium amounts in older guinea pig’s bodies can cause complex health problems and can be fatal for them.

Please note that other treats such as acorn squash, dumpling squash, buttercup squash, or any other squash can substitute pumpkins.

That said, it’s crucial to consider the amount of sugar and calcium your pet eats every time.

Is Pumpkin Dangerous to Guinea Pigs?

Although feeding pumpkins to guinea pigs is healthy, it’s risky if not done the right way.

Before feeding guinea pigs, you have to consider the pumpkin’s size, content, cleanliness, and other factors such as foods with similar nutrients.

Please note: the number of certain nutrients in your guinea pig’s food should be balanced as, otherwise,  your guinea pig might start coping with various illnesses.

Below are some health risks that can happen if you don’t pay enough attention.


Choking can occur if you give your guinea pig the parts of pumpkin that are inedible for your pet.

Although most guinea pigs eat pumpkin and love it, you should never give them the seeds.

Pumpkin seeds are sharp and inflexible, hard to chew, and get stuck in the mouth and throat of guinea pigs.

This can be a major choking hazard for them.

That’s why you should never allow your guinea pig to eat pumpkin seeds.

In case they have eaten pumpkin seeds by accident, it’s crucial to contact a vet as soon as possible.

Digestion Pain and Diarrhea

Because they have fragile stomachs, they cannot digest the high amount of sugar in pumpkins.

In addition to that, if your guinea pig successfully ingests pumpkin seeds (which rarely happens) the high amount of starch and fat causes stomach ache that leads to diarrhea.

It’s been found that excess sugar with a large serving size causes diarrhea, leading to death if not treated on time.

As a result, you should always limit your pets’ sugar intake.

Please note: if your guinea pig is suffering from diarrhea, obtain a fecal float and check for parasites. However, if you’re not sure about this procedure, take your guinea pig to a vet.

Urinary Problems

The urinary problem can be caused if the amount of calcium in guinea pigs is too high.

Remember, only young guinea pigs need a high amount of calcium in their diet for their growth and development.

If the amount of calcium in grown guinea pigs is high, they’re at risk of developing infections in their urinary tract, blood in urine, urinary stones, and pain during urination.

To avoid that, you should regularly measure the amount of calcium they are getting.

No one’s perfect and mistakes can happen, so it’s necessary to diagnose guinea pigs for urinary problems by:

  • examining the frequency of bedding urination
  • looking for blood in their urine
  • listening for squeaking while peeing
  • other abnormal behaviors

The earlier you realize that your pet has urinary problems, the earlier you can take it to the vet.


Scurvy (caused by lack of vitamin C) in guinea pigs is highly dangerous.

Scurvy, a fatal disease for these little pets, reduces their appetite, causes loose stool, damages their fur, and causes internal bleeding.

Guinea pigs cannot produce vitamin C naturally so they need to get it through their daily supplements.

They need to get vitamin C of 10 – 30mg per 1 kg of weight every day and 26 – 39mg of vitamin C for 1.3 kg daily to avoid the risks and stay healthy.

Hence, you have to make sure that your pet’s diet contains high amounts of vitamin C.

If you think that your guinea pigs may have scurvy, it’s important to take them to a veterinarian as soon as possible.

Which Part of the Pumpkin Can Guinea Pigs Eat?

Let’s learn more about which parts of the pumpkin your guinea pig can eat.

Pumpkins consist of rind or skin, seeds, leaves, stem, pulp, flesh, and flowers as edible parts.

Because of the various nature structures, contents, and properties, guinea pigs can only eat some parts of pumpkins.

Moreover, you should never offer your pets processed and cooked foods; instead, offer them raw pumpkin slices.

All parts of the pumpkin are rich in nutrients.

Let’s see the different parts of a pumpkin and find out which ones are safe for guinea pigs.

Can Guinea Pigs Eat Pumpkin Rind?

Pumpkin skin is the orange-yellow upper cover or the skin of the pumpkin.

So, can your guinea pig eat pumpkin rind?

There’s been a wide misunderstanding in this, many people share the idea that pumpkin skin is not nutritional and it’s supposed to be peeled but the opposite turned to be true.

Some studies have reported that pumpkin skin has more nutrients than flesh.

It is an excellent source of antioxidants, minerals, and vitamins compared to pulp and flesh.

Studies also found that pumpkin rind is good for your guinea pig’s teeth which keeps them strong and healthy.

Therefore, most guinea pigs eat pumpkin rind and it is beneficial for them.

The only requirement to get all these benefits out of pumpkin’s rind/skin is to properly clean them thoroughly and feed them along with the flesh.

Can Guinea Pigs Eat Pumpkin Seed?

Pumpkin seeds are the small white-yellow grains inside the pumpkin.

Are pumpkin seeds safe for guinea pigs?

We have already warned about the dangers of feeding pumpkin seeds to your pets.

The answer to this question is no.

Pumpkin seeds have a hard texture, sharpness, and inflexibility; guinea pigs can’t chew them easily and get their teeth damaged.

These seeds get stuck inside their mouth and throat and can be a major choking hazard for guinea pigs.

Can guinea pigs eat pumpkin seeds after grinding them?

Guinea pigs cannot digest processed and cooked foods.

So, by any means, you shouldn’t allow your guinea pig to eat pumpkin seeds.

Can Guinea Pigs Eat Pumpkin Flesh?

Pumpkin flesh is found between the pulpy inside and the rind or peel of the pumpkin.

As the name indicates, it’s the flesh part of the fruit which is mainly eaten.

Following that, there’s the pumpkin pulp which is attached to the inside of the flesh containing the seeds.

It’s been found that these parts of pumpkin have the ability to reduce cancer risks, protect against heart disease and asthma, decrease muscular degeneration.

Pumpkin pulp and flesh are nutritious and healthy, so your guinea pig can eat pumpkin pulp/flesh but in moderation because too much pumpkin can be harmful to your pet’s wellbeing.

Please, don’t forget to remove all the seeds before giving pumpkin slices to your guinea pig.

Can Guinea Pig Eat Pumpkin Leaves?

Like any other vegetables and fruits, guinea pigs love to eat pumpkin leaves.

Pumpkin leaves are highly nutritious and healthy.

They are low in calories and consist of a high amount of iron, vitamin A, vitamin B, vitamin C, and calcium, which are all beneficial for your guinea pig’s immune system.

Guinea pigs eat pumpkin leaves with pleasure but only after you remove the prickly spines and cleaning them with water.

Remember: you can’t feed them more than an inch at a time because of the high content of calcium in the leaves, which can cause kidney and bladder stones.

Can Guinea Pigs Eat Pumpkin Stems?

Pumpkin stems are the slightly brownish-green handles of the pumpkin.

These stems are fully green when the pumpkins are young and growing, and eventually, change their color when they grow.

Guinea pigs find pumpkin stems to be hard both for their molars and digestion.

An alternative for these stems could be the pumpkin leaf stem which is more nutritious and keeps guinea pig’s teeth healthy.

So, it’s advisable to feed on pumpkin leaf stems which contain high nutrients and are easy to chew, then the main stem or the handle which contains low nutrients and is hard to chew.

Again, you need to remove their spikes, clean them with water, and serve them in small amounts just like the leaves.

Can Guinea Pigs Eat Pumpkin Flowers?

Pumpkin flowers are the beautiful yellow flowers of pumpkin that grow on the pumpkin leaf stem.

An amazing fact about pumpkin flowers is that they contain more vitamin C than most fruits.

Pumpkin flowers have several health benefits: are rich in vitamin B9 that enhances immunity against certain viruses, improves vision, and encourages bone strength.

But as a result of their calcium content, it’s advised that we only give them slightly.

Can your guinea pig eat fresh pumpkin flowers?

Yes, definitely, but only in a small amount after you have carefully washed them in water.

What Types of Food Can Guinea Pigs Eat?

There’s a range of options for feeding your guinea pig at home; here is the list of foods you can give to your little pet:

  • Broccoli
  • Broccolini
  • Cucumber
  • Carrots
  • Carrot tops
  • Zucchini
  • Cauliflower
  • Sweet potatoes
  • Mint
  • Summer squash
  • Cabbage
  • Arugula
  • Asparagus
  • Green beans
  • Parsley
  • Butter lettuce
  • Bibb lettuce
  • Escarole
  • Swiss chard
  • Brussels sprouts
  • Beets
  • Beets tops
  • Bell peppers
  • Parsnips
  • Romaine
  • Artichokes
  • Cilantro
  • Apple
  • Orange
  • Mangoes
  • Grapes
  • Strawberries
  • Blueberries
  • Cantaloupe

and other fruits and vegetables.

All these fruits and vegetables have different nutritional values.
For that reason, you should learn more about the exact amount of these foods your guinea pig can consume without detrimental effects on its wellbeing.

Can Guinea Pigs Eat Processed Pumpkin Products?

Processed and cooked pumpkin products are not something guinea pigs can eat while staying healthy.

Let’s have a look at some of the most common pumpkin products and their values to guinea pigs.

Pumpkin puree

Pumpkin puree is processed and cooked pumpkin flesh.

It can be homemade or bought from the market as a canned pumpkin puree.

Canned pumpkin puree has a variety of unhealthy chemicals that could irritate guinea pigs.

Even though it’s preserved and says it is 100% pumpkin, canned pumpkin puree has preservatives, other chemicals, and few amounts of sugar.

Even the homemade pumpkin puree isn’t recommended for guinea pigs because it’s been cooked and processed.

Again, you should only give your pets raw pumpkins.

That makes both canned and homemade pumpkin puree unsafe for guinea pigs’ health.

Therefore, never feed your pets with processed food.

Guinea pigs cannot digest it.

Butternut pumpkin

Butternut pumpkin has rich nutrients and has numerous health benefits.

High oxalic acid, vitamin A, vitamin C, beta carotene, fiber, potassium, and magnesium are all present in butternut pumpkin, important for your pet’s immune system.

These nutrients along with others enable butternut pumpkins to reduce various chronic diseases.

Butternut pumpkin mostly has the same nutrients as other pumpkins but a little more sweetness and nutty flavor.

That said, your guinea pig shouldn’t eat butternut pumpkin more than twice per week to stay healthy.

Pumpkin pie filling

A pumpkin pie, the traditional dessert for thanksgiving, contains sugars and several sweeteners, so it’s not a good idea to let your guinea pig eat it.

Pumpkin pie filling contains eggs, cinnamon, sugar (both brown and white), salt, nutmeg, cream, and other products that are not healthy for guinea pigs.

Guinea pigs can’t eat pumpkin pie because they are processed.

Another reason why your guinea pig cannot eat pumpkin pie as it contains excessive amounts of sugar which the guinea pig’s digestive system cannot process.

So, it’s recommended that you don’t feed pumpkin pie to your guinea pig.

Canned pumpkin

Canned pumpkin is a cooked pumpkin and has fewer nutrients than fresh pumpkin.

Even if it has no additives, guinea pigs can’t eat them because they’re cooked and it’s been found that canned pumpkins are actually strains of squash.

The guinea pig’s digestive system cannot process cooked food.

Therefore, guinea pigs can eat pumpkin but only raw and in a small amount.

For this reason, it’s only recommended to feed guinea pigs with raw pumpkins.

Mini pumpkins

Mini pumpkins contain high nutrition values and are healthy for guinea pigs.

The beta carotene, vitamin A, vitamin C, other vitamins, and minerals contained in mini pumpkins make them highly beneficial for guinea pigs’ immune systems.

Considering the amount and size, it’s healthy to allow your guinea pig to have mini pumpkins but not more than two times a week.

How to Feed Pumpkin to Guinea Pigs?

Prepare only raw pumpkins for your guinea pig because they can’t digest cooked foods.

Wash all the pumpkins correctly to avoid all dirt and unwanted chemicals including bacteria and other fatal microorganisms.

Remove all seeds before feeding your guinea pigs.

Limit the amount of pumpkin by considering all the other food and treats you allow your guinea pig.

Clean their living areas frequently before and after feeding.

Take them to a veterinarian when you see any illness in your guinea pig.

Remember: pumpkin rind/skin is highly beneficial for guinea pigs and there is no harm in eating it, so peeling off its skin is waste of time and nutrition.

Final Thoughts

As you can see, guinea pigs can eat pumpkins, and most like pumpkins more than other fruits and vegetables because of their sweetness.

However, your pet’s diet should primarily consist of high-quality guinea pig food that contains more vitamin c, timothy hay, and clean water that you frequently change.

Feeding pumpkins to your guinea pig as a treat is very healthy.

Many people believe that feeding pumpkins to their pets up to three times per week are fine.

However, in reality (based on real-life experiences and experimentation) they can’t eat pumpkin more than twice a week and stay healthy.

They either suffer from diarrhea or develop urinary problems gradually.

Guinea pigs can eat pumpkin, its rind or skin, pulp, flesh, leaves, and flowers in moderate amounts to get all the benefits from them.

You should avoid feeding pumpkin seed and stem to your pets as they are highly detrimental to your guinea pig.

Guinea pigs can’t eat cooked food so only allow fresh and raw pumpkins.
