Can Guinea Pigs Eat Pineapple?

Understanding which foods your pet guinea pig should and should not eat is an essential part of being a responsible pet owner. 

When it comes to pineapple, many people are confused about whether they should feed it to their pet piggies.

As a general rule, pineapple is a safe fruit to feed to your guinea pig. This fruit is high in vitamin C, which is an essential nutrient for these animals. Although it has beneficial qualities, pineapple is also high in sugar and should be given in moderation.

There are both health benefits and risks associated with feeding your pet pineapple. 

Let’s take a closer look at what these benefits and risks are and common health conditions associated with fruit consumption.

Is Pineapple Safe For Guinea Pigs?

Feeding this fruit to your pet cavies will have them begging for more. 

This juicy treat is a fan favorite among cavies and is often part of an exciting diet.

If we know our pets love this fruit, why is it essential for the owner to limit their consumption? 

We’ll get to the risk factors associated with this topical treat, but first, let’s learn a little more about the nutrition facts and what benefits it provides.

The following table includes the nutrition facts of 100 g of fresh pineapple.

Benefits Of Pineapple For Guinea Pigs

If you have read the table above, you are able to see there are several beneficial nutrients present in the fruit, including adequate amounts of calcium, potassium, and vitamins A and C.

Simply knowing this food has these essential nutrients does not fully explain what beneficial factors it brings to your pet’s diet. 

We must explore how each of these nutrients works for our pets and what happens if they develop a nutrient deficiency.

Calcium & Phosphorus

Calcium is an essential mineral for almost every living creature, including your pet cavies. This mineral helps support strong bones and teeth.

If they do not get enough calcium in their diet, their bodies will supplement this deficiency by taking the mineral from their bones and teeth. 

This will lead to a weakened skeletal structure, making them more prone to broken bones. 

It may also cause other health issues like a dental disease.

Dental disease is a painful condition which will eventually lead to other concerns like the refusal of food, weight loss, diarrhea, or constipation. 

Cavies suffering from these issues often fall into a depressive state, which is detrimental to their health and may be fatal.

Guinea pig teeth grow at a continuous rate. 

This continuous growth needs to be managed in some way. 

These animals naturally file their teeth down by chewing on hard objects. 

They must have constant access to untreated wood or guinea pig chew toys.

If your pet has a calcium deficiency or dental disease, chewing on hard substances is painful and sometimes near impossible. 

Essentially, a calcium deficiency will lead your pet down a road of building health concerns.

While this mineral is vital for your cavies, you will also see “no calcium” diets on the market. 

This is because too much calcium is also bad for their health and will lead to bladder stones.

Bladder stones are a common health concern for these animals, and they often require surgery. 

In some cases, the stones may be detected at an early stage. 

If this occurs, your guinea pig may be able to pass them naturally with an increased water intake.

In most cases, the stones become too large to pass naturally, and surgery to remove these stones is the only way to save the animal’s life. 

In general, you will not need to worry about overdosing your pet with calcium.

We suggest naturally supplementing your pet’s diet with this mineral by feeding it foods with adequate amounts of calcium and monitoring its urinary patterns.

Providing foods like ripe pineapple will allow you to accomplish this appropriate calcium intake. 

This food has good calcium to phosphorus ratio (Ca:P), measuring at approximately 1.6:1. 

This is a crucial ratio to keep in mind because phosphorus will inhibit an animal’s body from absorbing calcium from its food.


Potassium is another essential nutrient present in this tropical fruit, with 109 mg present per 100 g. 

Of course, you will not be feeding your pets 100 g of this fruit in a single serving, so the levels they consume will be lower than this measurement. 

We use the nutrition facts of 100 g of food for the most straightforward understanding and conversions for pet owners.

Potassium helps support vital organ health by aiding in muscle contraction and keeping the heartbeat regular.

It aids in the absorption of other nutrients in the cells.

Potassium also helps to offset the harmful effects of sodium in the blood.

The main benefit of this nutrient is its ability to support water retention in the body.

Water retention will ward off bladder stones from forming.

Vitamin A

This nutrient supports internal organ function, a healthy immune system, and quality of vision.

A deficiency of this nutrient may become present in your pet, with warning signs appearing after several weeks.

Poor growth rate and weight loss are both signs of a deficiency.

Other conditions such as skin irritation and loss of vision may also develop.

A weakened immune system is the most significant risk for cavies, making them more susceptible to pneumonia, the leading cause of death in these animals.

This delicious fruit provides some amounts of vitamin A but will not be enough to sustain your pets regularly.

Ensure you are incorporating other foods rich in this nutrient in their diets.

Vitamin C

Vitamin C is arguably the most important essential nutrient for cavies. 

Their bodies do not produce this nutrient on their own, so you must supplement it in their diet daily.

Vitamin C supports a robust immune system and helps reduce the risk of developing dental diseases like scurvy. 

Pineapple provides plenty of this nutrient, measuring 47.8 mg per 100 g.

On average, a cavy requires between 10 mg and 30 mg of vitamin C per day. 

Even a few cubes of pineapple once per week will supply your pet with substantial levels of this nutrient. 

Many staple foods in this animal’s diet, like kale and parsley, are excellent vitamin C sources.

A lack of vitamin C will lead to a multitude of health issues, including scurvy. 

Scurvy is a dental disease which causes bleeding of the gums, open sores, and a weakened body.

Risk Factors Of Pineapples For Guinea Pigs

Along with health benefits, consumption of this fruit also comes with various risk factors. 

Like many fruits, pineapple has high sugar content.

With 9.85 g of sugar per 100 g of fruit, this food ranks high in sucrose levels. 

High amounts of sugar in a cavy’s diet will cause weight gain and lead to obesity and diabetes.

Excessive weight gain is dangerous and will make it difficult for your pet to keep up with its cage mates. 

A decrease in exercise and playtime will take a toll on your pet’s physical and mental health.

Too much fruit may also lead to digestive issues like diarrhea. 

Diarrhea is dangerous for these pets. 

If you notice your cavies having digestive issues after eating certain foods, be sure to stop adding them to their meals and look for suitable substitutes.

Pineapple is a very acidic fruit. High acidity levels in a cavy’s diet will lead to mouth sores and irritation of the stomach and digestive tract. 

Feeding your pets food with high levels of natural acid will leave them with an upset stomach. 

Bodily pains like stomach issues will cause stress in your cavies.

What Parts Of Pineapple Are Safe To Eat?

Parts of this fruit, such as the pineapple skin and core, are a choking hazard. 

When feeding this fruit to your guinea pigs, be sure to remove all parts of the skin and core. 

This includes the hard little brown circles often left on the flesh after removing the pineapple skin.

Many vegetable peelers have a rounded end at the tip. 

Use this tip as a little spoon to cut around the hard spots and scoop them out. 

If you do not have a peeler with this feature, cut the fruit down even further.

This may be obvious to some owners, but it should be noted the leaves of pineapple should never be part of the meal.

Pineapple Serving Size And Frequency For Guinea Pigs

Since we now know the benefits and health risks associated with this fruit, let’s discuss serving sizes and feeding frequency.

If you are the owner of baby guinea pigs, it is best to refrain from feeding them this fruit in general. 

Although it is an excellent source of vitamin C, it should only be fed to fully grown piggies.

To minimize potential risk factors, only feed a few pieces of pineapple to your pets as an occasional treat. 

We suggest only providing this fresh fruit once per week at most. 

Two to three small cubes should suffice.

Variety is the spice of life, so consider switching up the fruits you give your guinea pigs. 

For instance, if you feed them pineapple one day, opt for strawberry slices or watermelon for their next treat.

We have a dedicated post to feeding guinea pigs watermelon if you want to learn more about it.

If your pet is particularly fond of this food, use it as a training treat. 

Cut the cubes into smaller pieces and use them to motivate your piggies to complete fun activities such as mazes or obstacle courses.

Typical Guinea Pig Diet

A typical guinea pig diet consists of 90% pellets and hay and 10% fruits, vegetables, and leafy greens.

Cavies are natural grazers and will spend a large majority of their day eating hay. 

The most common choice among owners is second-cut timothy hay. 

This is the most nutritious cut of hay and is easily accessible. 

We suggest this Kaytee second cut timothy hay found on Amazon.

For a better understanding, an average guinea pig should only consume approximately one cup of produce per day. 

The majority of each cavie meal should consist of healthy greens and fresh veggies, leaving a small portion dedicated to fruit.

Your piggies will require a constant supply of fresh, clean water. 

This means you will need to wash their water bottle every day and fill it with fresh water. 

Some owners have busy schedules and do not always remember or have time to wash the water dispensers.

We suggest owners have a spare dispenser on hand. Having this extra dispenser will allow you to quickly change the water source at the beginning of every day. 

You will then clean the dispenser when you have time later in the day or the evening. 

Whether you have spare bottles or only one, it is essential to clean your piggies’ water source daily.

Healthy Treats For Guinea Pigs

Pineapple is often a favorite treat among cavies. 

However, there are plenty of other fruits they enjoy. 

If you are looking for a variety of safe fruits to feed your pets, review the recommended healthy treats list below.

Safe Fruits

  • Apples
  • Apricot
  • Banana
  • Blueberries
  • Strawberries
  • Raspberries
  • Cherries (no pit)
  • Seedless grapes
  • Kiwi
  • Papaya
  • Mango
  • Passionfruit
  • Peaches
  • Plums
  • Pear
  • Nectarine
  • Tomatoes (no stem/leaves)
  • Honeydew melon (remove seeds)
  • Cantaloupe (remove seeds)
  • Watermelon (remove seeds)

One of the most commonly incorporated fruits in a cavy’s diet is a tomato. 

Tomatoes are nutritious and rich in vitamin C. 

Be sure to remove the little stems and leaves at the top of the tomatoes, as they are poisonous to guinea pigs and should never be consumed.

No matter what fruits you choose to give your piggies, keep in mind, they should be thought of as treats and not dietary staples.
