Can Guinea Pigs Eat Bananas? Banana Peels?

It’s easy to feed your guinea pig with the wrong food if you are not well informed. If you’ve never had a guinea pig before, you can see it as a challenge to plan their diet in a way to makes it well balanced and nutritionally rich.

Every pet owner wants to give their pet the best, so make sure you know which ingredients are the right ones and which ones are not. Are you a lucky owner of guinea pigs? Have you been wondering, can guinea pigs eat bananas? Or maybe, can guinea pigs eat banana peels? 

Luckily for you, you’ve come to the right place, because here you will learn all about guinea pigs and bananas. Read below and learn some new interesting things today. 

Can Guinea Pigs Eat Bananas?

The answer is yes!

Bananas are safe for guinea pigs to eat as long as you keep them in the form of raw bananas. Never feed them dried bananas or banana chips since they are always coated with additional sugar, and they are highly processed, which is never a good option. 

Bananas are an excellent sweet treat since they are high in sugar. But see how I stated they are a treat; that’s why bananas should be fed occasionally.

So remember only to feed your guinea pigs with fresh, ripe bananas.

Let’s Talk A Bit About Bananas

Bananas are a delicious sweet, and soft fruit enjoyed all around the world by both humans and pets. Is there a person who does not go bananas about bananas? Yeah, there are probably some cases, but bananas are crazy tasty, and none can say no to them.

They are usually eaten by themselves, but many people incorporate them into dessert dishes like an extra special treat like banana bread. Oh, don’t get any crazy ideas, and do not feed your guinea pig with banana bread!

Bananas are mainly grown in tropical regions, and the interesting fact is that every banana plant produces 10 to 20 bunches of bananas once in its lifetime. After the bananas are harvested, the tree will be cut down, and that’s all, folks!

But that is not sad; the sad thing is that banana trees clone themselves to reproduce, which makes them genetically vulnerable and susceptible to diseases, so they are technically always at the risk of being wiped out. 

There are a few varieties of bananas, the most common one is the Cavendish banana, the previous most common variety was Gros Michel, but that one died out, unfortunately.

Are Bananas Good For Guinea Pigs?

As already said, bananas are great for them in small amounts, as a treat, from time to time. The great thing about this super fruit is that they contain vitamin C, which is a crucial part of the guinea pig’s diet! Guinea pigs are herbivores, so they have a mainly plant-based diet.

Hay and alfalfa pellets make the most of their diet, so occasional treats in the form of some fruit are a great way to enhance their diet and overall health. Hay provides essential fibers and proteins that maintain their guts healthy and enhance motility. 

Guinea pigs also require fresh water and veggies to keep their diet balanced and to stay well hydrated. Leafy greens will provide hydration and a wide variety of vitamins, so do not forget to toss in some leaves each day and keep your piggy happy.

They adore leafy greens like kale, romaine lettuce, and spinach, and they are all nutritionally very rich. Also, once a week, add in some sweet potato, zucchini, and carrots

Different stages of development require different nutrients; infancy, pregnancy, and adulthood are never the same. Disease like scurvy is common in guinea pigs. This is a disease caused by vitamin C deficiency.

Skin and bone health significantly decreases in vitamin C deficiency, and also, they quickly lose a lot of weight. Guinea pigs, just like us humans, cannot produce their own vitamin C, so they need to be supplemented with it. There are a lot of specially formulated vitamin C supplements for them that you must use but add some bananas in their diet from time to time to enhance the vitamin C intake.

How Much Bananas Can Your Guinea Pig Eat?

A small amount means a small slice on occasion. Because of the high sugar content, they are not an optimal food for your pet, and increased amounts of sugar can cause serious health issues in guinea pigs, such as diarrhea and diabetes.

Diarrhea is usually a symptom of other health issues, but loose stools can also be caused by high sugar intake; this can happen to humans as well, be aware! Sugar also leads to diabetes, and piggies can get both type 1 and type 2 diabetes, just like us. 

Don’t get me wrong, piggies will likely develop this disease when they are overweight, but sugar is always a contributing factor. The great news is that guinea pigs can go into remission from diabetes. The only thing you must do is to correct their diet and maintain their healthy weight. 

Can Guinea Pigs Eat Banana Peels?

This might sound like a weird question, but yes, I will give you an answer to it.

Giving your guinea pig a tiny piece of a banana peel won’t harm them. Banana peels are fully packed with all sorts of goodies, so why not bring that into their diet! 

Banana peels are full of antioxidants, and their levels vary at different ripeness of peels. An unripe banana peel has the highest antioxidant content, which is great for fighting free radicals. Free radicals can cause conditions like cancer and heart diseases, so why not do everything you can to avoid these problems.

Banana peels also contain vitamins B6 and B12, magnesium and potassium, as well as fibers and proteins. Magnesium is crucial for metabolism, while potassium is vital for muscle movement.

But how much banana peel should I give to my furry friend? 

The best way is to start small. Grab a ripe or unripe banana, depending on which one you have at that moment. Remove the peel and wash the peel properly, then cut a very small piece. Let your guinea pig smell it first so they can decide whether they want to give it a shot or not.

They will most likely gobble it up, so you can occasionally serve it as a treat but never at the same time when feeding banana slices.

Can Guinea Pigs Eat Banana Chips?

I already said no, but you can never be too cautious. 

Bananas are already high in sugar, and banana chips always contain additional sugar content. So this means they should never be fed to your guinea pigs. Anything with added sugar is bad for your piglet, period.

Also, banana chips have added oils and some additional artificial flavorings; both are not good for your guinea pigs. So avoid banana chips and dried bananas always! Stick to the fresh fruit.

Are Bananas Harmful For Guinea Pigs?

No, they are not, but they can be if you are feeding your guinea pig with too many bananas. All fruits can damage their health. Let’s see how:

  • They can become overweight, so they will experience issues like cellulite and heart problems. If this happens, you’ll have to put them on a reduced-fat diet and include exercises to get them back into shape.
  • Guinea pigs have higher fat content in their body than other rodents, so their diet has to be controlled more carefully. They can easily overheat and pick up a lot more weight.
  • Guinea pigs will have diabetes when consuming too many sweet treats, but luckily with correct steps, they can be cured.


Guinea pigs have a very specific diet, and if this is your first time as a guinea pig owner, the chances are high that you still don’t know what that is yet. Do some research since there are plenty of diet plans available online. The best way is to visit a pet store and buy specialized guinea pig food.

When you want to treat your guinea pig, make some healthy treats at home or serve them a slice of banana or any other fruit. Just remember, the only thing that matters is the amount. The high amount of any food will for sure endanger your guinea pig.
