Can Guinea Pigs Eat Bananas? – Things You Should Know

Bananas are rich in nutrients, and they’re significantly beneficial for us humans. Everyone, well, most of us love to eat bananas or make banana smoothies.

“It is perfectly safe for you to feed your guinea pig a delicious banana. It is filled with all the necessary nutrients that a guinea pig needs. But make sure not to overfeed your guinea pig. A few bites will be enough for him to enjoy and benefit from its nutrients.”

Guinea pigs can safely eat bananas just like they can eat grapes, blueberries, and celery but in small proportions.

Before we get into further details, you should first understand the different states or stages of bananas.

The Different States OF Bananas – Which State Is Ideal For Your Pet Piggy?

These aren’t different varieties of bananas. These are essentially the various stages of ripening of a banana. These include

  • Firm and often green ones.
  • Yellow bananas
  • Slightly black bananas or the ones with patches.

Fresh from the tree and close to harvest, you can find them being green and firm. In general, they are not suitable to eat in this state even for us.

They will give you stomach pain that’s for sure. Because in this state they are hard and they have a strange sort of taste. This also applies to your guinea pig and is definitely not recommended for your guinea pig.

Over the course of a few days to a few weeks, they gradually turn soft until they finally turn yellow and then slightly black.

The state that people and guinea pigs in general want is from yellow to slightly black.

Slightly black bananas can be generally soft and brown with a sweet taste.

This does not indicate that they have gotten worse, but that they are going there. Once they turn completely black, you should avoid feeding such bananas to your furry little friends.

This is why you should only feed your guinea pig with bananas that are either yellow or slightly black.

Can Guinea Pigs Eat Bananas? – 9 Basics You Must Know

Bananas are rich in potassium and vitamin C, which are very good for the health of guinea pigs.

However, bananas are also rich in sugars. They have a high concentration of sugar. This is the primary reason behind feeding a banana to your guinea pig in small amounts.

Foods with a high concentration of sugar are bad, even for humans. Try to keep sugar intake as minimum as possible for the guinea pig.

A higher amount can harm the guinea pig’s stomach, which can lead to constipation.

Bananas are the most loved fruits both by humans and animals. It won’t be wrong to assume that they are one of the most famous fruits in the world having numerous healthy nutrients.

Here’s everything you need to know when introducing bananas to your cute little guinea pig.

1) How Many Bananas Can A Guinea Pig Eat?

Only serve one small banana per guinea pig.

Because it is high in natural sugars, eating too much will lead to adverse health effects.

Too much sugar is never a good idea and is terrible for your guinea pig’s health.

2) What Is The Right Amount?

The right amount of feeding a banana to your guinea pig is no more than 10 to 15 grams a week.

Feed small piece of banana to guinea pigs

Cut a small piece of banana and ensure it doesn’t exceed the recommended dose of 10-15 grams once a week.

We should try to feed him according to this serving size. The guinea pig diet contains only 5-10% of the total fruit, and it is important to maintain that balance.

If you increase this ratio, you can distort the balance.

3) What Happens If Guinea Pigs Eat Too Many Bananas?

If you fear that your guinea pig will eat too many bananas, there is nothing for you to worry about.

They will experience bloating, flatulence, constipation, and muscle cramps.

Your pet friend will stay in one place, and they will emit some sharp sounds to let you know that they are feeling awkward.

To help their digestion, you can try to give them plenty of water to help them wash away the sugar they ate.

But, if constipation and pain continue for more than a day, you should check them to make sure nothing serious has happened. A visit to the veterinarian will be a good idea at this stage.

4) Can Guinea Pigs Eat Bananas Peels?

A lot of people claim that banana skins or peels do not cause any harmful effects to the health of these little furry creatures.

“Yes, guinea pigs can eat bananas with their peels. While you can feed them bananas with peels, guinea pigs won’t necessarily eat them. Guinea pigs like more of what’s on the inside.”

However, you should always properly wash and clean them if you ever decide to feed a banana to your guinea pig.

guinea pig should never be fed dry or old banana skins

Another important thing is that your guinea pig should never be fed dry or old banana skins because they have no nutritional benefit for your little friend.

5) Can Guinea Pigs Eat A Whole Banana?

Guinea pigs can only eat a small bit of banana and can never eat a whole banana.

Keep in mind that they are very small compared to us. We cannot give them a whole or one and a half bananas, which is not logical.

On the other hand, in the case of banana skins, if even the guinea pig wants them, still you can’t feed the whole peel to him.

One or two small pieces are enough for him to enjoy.

6) Can Baby Guinea Pigs Eat Bananas?

Are bananas good when guinea pigs are babies?

To be honest, you should not give bananas to baby guinea pigs, especially in the first few weeks after they are born.

They only need their mother’s milk at that time and maybe hay.

You can introduce a baby guinea pig to vegetables and fruits after sometime around a few weeks. But only in small quantities and not that often.

At that time, bananas are good for them due to potassium, which is good for the development of the baby guinea pig.

7) Is It A Good Idea To Feed Guinea Pigs Banana Peppers?

“No, you cannot feed banana peppers to your guinea pigs.”

This is because these peppers are considered hot since they are members of the chilli pepper family.

They taste milder than jalapenos peppers. Guinea pigs should not be given chilli due to their sensitive digestive system.

Feeding banana peppers to your guinea pigs can cause severe stomach issues which you don’t want.

But what about feeding them sweet bananas? Your guinea pig can have some sweet banana peppers.

This pepper is similar to bell pepper having a banana-like shape. Guinea pigs love eating sweets and will definitely enjoy eating sweet peppers.

8) Are Green Bananas Good For Guinea Pigs?

Another thing that people ask a lot is can guinea pigs eat green bananas? Well, Yes, they can!

But, some guinea pigs do not enjoy green bananas that much.

This is because they taste a bit strange.

Yellow and green bananas differ in texture and taste

Yellow and green bananas differ in texture and taste, but both are full of healthy nutrients.

The main difference between them is that of taste. Green bananas have a slightly bitter taste because of less concentration of sugar.

Also, green bananas are hard as compared to yellow bananas. Therefore, guinea pigs can be fed with green bananas and in less quantity.

9) Can Guinea Pig Eat Banana Leaves?

Many people use banana leaves for the purpose of cooking, serving, or wrapping. This is due to its large size and hard waterproof texture.

But can guinea pigs eat banana leaves?

The answer is simple, YES! Guinea pigs can eat banana leaves occasionally.

Banana leaves don’t really have any problems, but they are very hard structured.

So, they can cause some digestive issues for guinea pigs.

A number of owners have even claimed that their pet pig loves to eat banana leaves and are their favorites.

But like any kind of fruit and vegetable, banana leaves should only be given once or twice a week.

Hay should be the main food in the guinea pig diet.
