What is a Guinea Pig?

A guinea pig is a type of pocket pet that resides in the cavie family of animals.

They are small animals that grow to a maximum of approximately 10-11 inches long, and can weigh up to 2.5 pounds as an adult.

In captivity and with proper care it is fairly common to see these pets live to 8-10+ years of age.

One of their main anatomical (body) “quirks” is that they are constantly needing to chew in order to file down their teeth, as their teeth are constantly erupting (growing longer).

They are quite playful animals and love to socialize with the ones that they know and love.

They make great pets for responsible pet owners, and those living in small dwellings wanting a loveable pet that comes in a small package.

What Do Guinea Pigs Typically Eat?

Guinea Pigs eat an assortment of things to keep them healthy and happy.

  • High-quality guinea pig food and Timothy hay should be the main staples of their diet.
  • Up to about 10% of their diet can be made up of an assortment of vegetables and fruits, with fruits and vegetables over 12-24 hours old being discarded as soon as possible.
  • They require 30 – 50 mg of vitamin C daily from their diet, either in their guinea pig food, a vitamin supplement, or from fruits and vegetables that are high in vitamin C. I’ll get to this more here in a sec…
  • Guinea pigs do best with diets low in fats and sugars.
  • Clean, fresh, filtered, chlorine-free water. ‘Fresh water‘ means that is is changed daily. ‘Changed daily‘ means that new water is placed into a CLEAN water dispenser!

Let’s Talk Kiwifruit:

The kiwifruit is the berry part of a vine plant that is considered a perennial, which means that it can survive and come back year after year.

Called kiwi for short in the United States, the kiwifruit is a round or oval egg-shaped and sized fruit.

The fruit has a brown and distinctively fuzzy, thin but tough, outer skin that is edible.

Inside this fibrous skin is a soft green or yellow flesh with rings of very small black, edible seeds.

The kiwifruit is described as being anywhere from tart to sweet in flavor. The tender flesh is juicy because of it’s high moisture content.

Like many other fruits, kiwi can become bruised from rough handling quite easily.

Kiwi Health Benefits:

Kiwis are a very popular fruit because of their sweet flavor, interesting fuzzy exterior and tender green centers.

Kiwis have many nutritional benefits as well as delicious benefits. Here is one summary of a kiwi’s nutritional makeup:

“In a 100-gram (3.5 oz) amount, green kiwifruit provides 61 calories, is 83% water and 15% carbohydrates, with negligible protein and fat. It is particularly rich in vitamin C and vitamin K, has a moderate content of vitamin E, with no other micronutrients in significant content. Gold kiwifruit has similar nutritional value, but higher vitamin C content. Kiwifruit seed oil contains on average 62% alpha-linolenic acid, an omega-3 fatty acid. Kiwifruit pulp contains carotenoids, such as provitamin A beta-carotene, lutein and zeaxanthin.”

1. Vitamins and Minerals:

Kiwi contains many vitamins and minerals, including vitamin A, C, E, and K.

They also contain potassium, Folate, phosphorus, magnesium, iron, and calcium [source]. Potassium is an essential electrolyte that helps cells function. Potassium may help reduce the risk of high blood pressure, strokes, and even kidney stones [source].

2. Antioxidants:

Kiwi contains antioxidants [source], like carotenoids, that may help to prevent cell damage that harmful free radicals can cause. These antioxidants can help with things like preventing certain cancers and diseases.

3. Sugar Levels:

With how sweet their taste is, it shouldn’t come to you as a shock, that a kiwi contain a high amount of sugar, just like many other sweet fruits.

This means that kiwis need to be fed carefully to those pets that have metabolic conditions such as diabetes in which blood sugar levels can be an issue.

4. Water Content:

Juicy kiwis have a healthy concentration of water that can help keep small bodies more hydrated. Just make sure not to over-indulge your little critter, because too much water is not a good thing either!

5. Immune Booster:

Kiwis contain vitamin C, which has been linked to healthy immune systems and to boosting immune systems in need of a little extra help [source].

6. Fiber:

Kiwi also has quite a bit of fiber in them.

This is great news because fiber helps with satiety, keeping the pet feeling full after eating for longer as well as helps keep the gastrointestinal tract moving [source] and flowing smoothly as it should.

The Importance of Vitamin C For Guinea Pigs

Like humans and certain other animals like birds and bats, guinea pigs do not have the ability to make vitamin C.

Instead, guinea pigs must get this essential nutrient from the foods they eat in their diet.

Guinea pigs in the wild get their vitamin C from fresh grass sources.

Pet guinea pigs receive supplemental vitamin C from leafy greens, fruit and veggies, specialty fortified pellets or supplemental droplets placed in their water bottles.

Can Guinea Pigs Eat Kiwi?

After reading up on some of the health benefits and some of the risks that the consumption of kiwi brings with it, wouldn’t it be nice it you could just safely feed it to your pet guinea pig?

Well, you can feed your guinea pig kiwi…. but only in moderation. This means – in SMALL amounts!

Moderation = 1/2 – 1 teaspoon of kiwi is enough fruit for one guinea pig.

Because kiwis are high in sugar (and other vitamins and minerals that we need to be careful of), you must not feed it in excess to guinea pig or obesity and other health issues can arise.

Another reason to not feed too much kiwi to your guinea pig is the fact that kiwis contain acids.

Because kiwis have some natural acidity than some other fruits, you should not feed them in excess to guinea pigs because serious health issues (upset digestive system, etc.) can arise from too much acid in their diets.

Diet Tip:

In total, your guinea pig should have around 1/4 – 1/2 cup of fresh fruits and vegetables combined everyday, and no more than that.

And that 1/4 – 1/2 cup should not consists solely of kiwi!

Remember, kiwis are an acceptable treat to feed to guinea pigs as long as it is an occasional treat.

If your piggy does not eat the fruit, it will only sit in their cage and get old and eventually become unsafe to eat.

If your pet does not eat all of their 1/4 – 1/2 cup of fruits and vegetables within 12-24 hours, then you need to dispose of it for them.

The rest of their diet, the other 90% or so, should be made up of guinea pig food and hay.

You should feed this amount no more than 1-2 times per week and no two days in a row.

Is It Healthy For a Guinea Pig to Eat Kiwi?

A kiwi contains some essential nutrients including potassium, fiber, and Vitamin C, that can be helpful in keeping your cavy healthy.

Vitamins and minerals also has some other potential health benefits for your pet guinea pig:

  • Inflammation/Antioxidants: Multiple studies show that kiwis are a great source of anti-inflammatory compounds that help in fighting against inflammation.
  • Vitamins: A kiwi contains vitamin A, C, E, and K. Guinea pigs need vitamins to stay healthy and to allow their bodies to function properly. Vitamin C helps guinea pigs stay safe and adequately protected from diseases and strengthens their immune system.
  • Diabetes/Blood Sugar: Kiwis may help with glucose levels and glucose metabolism in the bloodstream.

May Reduce Inflammation

Multiple research studies have shown that kiwis are a source of anti-inflammatory compounds, which effectively can help fight different forms of inflammation found inside the body.

As mentioned above, kiwis are packed with these potential anti-inflammatory molecules called antioxidants, especially in the kiwi skin and flesh, which are rich in carotenoids – antioxidants with anticancer properties [source].

Antioxidants are thought to help reduce inflammation inside the body by binding (attaching) to and suppressing (decreasing) inflammation-promoting molecules known as free radicals. [source]

Source of Fiber:

Kiwis also contain a moderate amount of fiber, 3 grams in one medium, ripe fresh kiwi [source], which is an essential part of a guinea pigs diet as it helps in maintaining their digestive tract and gastrointestinal health.

How About Kiwi Stems and Kiwi Leaves?

Just like anything else that they can stick in their mouths, these items can be a choking hazard so I do not recommend offering your piggie these while snacking on this fruity treat.

There are other things you can give your guinea pig to chew on that would be better and safer for them.

Can They Eat Kiwi Seeds?

They definitely can eat the very small kiwi seeds!

The kiwi seed is quite small and slippery and should be of no choking issue to the guinea pig.

Can Guinea Pigs Eat Kiwi Skin?

I do not recommend feeding the skin of kiwis to your guinea pig.

Kiwi skin is tough and fibrous, yet the inside of the skin that contacts the juicy flesh is moist and slippery.

Given the fact that the skin is both tough and slippery, makes it a choking hazard in my book.

So I would recommend removing the skin before offering your furry friend any kiwi.

Can They Eat Dried Kiwis?

The higher sugar content of dried fruit such as dried kiwis makes me always say a resounding no.

Do not feed your guinea pig any dried kiwi pieces, stick with the fresh fruit.

Can They Eat Frozen Kiwis?

Frozen kiwis are quite hard and are a potential choking hazard, so I do not recommend offering your pet any frozen kiwi, even if they are already in smaller pieces.

Can They Eat Kiwi Jam or Preserves?

No, no, nope.

Do not ever feed your guinea pig jelly or jam as these are high in sugar.

High sugar content is not good for your little friend, so please stay away from the jellies and jams!

How To Feed Kiwi To Guinea Pigs:

Some Guinea Pigs will love the taste of kiwi and other piggies will find their favorite flavor elsewhere.

However, it is most often one of their favorite fruit to snack on.

  • fresh store-bought kiwi


  • kitchen knife
  • cutting board


    1. All fruits and vegetables will need to have a visual inspection done to make sure that you are giving your pet a ripe, healthy food to eat.
    2. Carefully remove the fuzzy skin from the fruit and dispose of it.
    3. Next, you will need to clean, cut, slice, chop, dice, or smash up the kiwi piece so that your guinea pig can safely eat it. They will need food in bite-sized pieces or small amounts of mashed kiwi.
    4. Watch for any adverse side effects of introducing this new food, before allowing them to have more of it at a later date.


Do not change or add new items to your pet's diet without talking with your veterinarian about it first. Contact your veterinarian immediately if adverse side effects arise after ingestion.

For starters, make sure to wash the kiwi thoroughly, removing any possible dirt, chemicals, or pesticides. Then remove the tough, slippery skin from the soft, tender flesh inside.

Then you can cut the kiwi into bite-sized pieces.

Make sure to use a clean knife and cutting board that are food-safe to do the cutting.

How Much Kiwi To Serve To Your Guinea Pig?

When introducing your guinea pig to anything new, you’ll always want to take it slowly and be very careful.

Start off by offering your pet just a single small kiwi piece the first time, and then watch for about 12-24 hours for any adverse reactions, such as digestive upset, diarrhea, decreased energy, not eating, etc.

If your guinea pig shows any signs of distress or discomfort, then you’ll want to stop feeding the kiwi pieces and contact your veterinarian about the current situation for further guidance.

That being said, most guinea pigs take to kiwis very well.

As long as your guinea pig shows no signs of an adverse reaction, you can gradually increase the amount of kiwi you are offering until they’re enjoying a full serving- which still isn’t a lot of the fruit!

It’s best to give kiwis once a week and to not exceed that.

You should serve no more than 1 – 2 small bite-sized kiwi pieces to your guinea pig a day and no more than once or twice a week.

Those few times a week also need to be spaced out – no two days in a row!

Is Kiwi Harmful To Guinea Pigs?

Yes, it can be harmful if not prepared, served, and monitored appropriately.

Too big of pieces could lead to the potential of being a choking hazard. Not good!

If the kiwi is not cleaned properly, then you leave your pet vulnerable to whatever was left on the herb, dirt, chemicals, pesticides, etc., which could potentially have harmful side effects.

Feeding too many kiwi pieces has its own set of issues to.

Guinea pigs can show digestive upset like diarrhea, decreased eating or anorexia, dehydration, lethargy, etc., that can lead to more dangerous health issues of not treated by your veterinarian.

Due to the sugar content and the small bodies of the guinea pig, guinea pigs are prone to becoming overweight (and also diabetes!) from eating too many fruits and snacks, such as kiwi.

Fruits contain acids which can give your guinea pig some uncomfortable side effects. Increased acidity can lead to mouth sores and medical issues.

If your guinea pig shows signs of any of these after introducing them to any new food in their diet, contact your local veterinarian immediately for more help.

Alternative Foods For Guinea Pigs:

There are many fruits, veggies, and herbs that are good for your guinea pig and for you!

Unfortunately, some foods are toxic to guinea pigs that are not harmful to us.

For this reason, it is very important to research every new food you plan to give your guinea pig and its corresponding serving size.
