The bulk of their diet should always consist of fresh hay and grazed grass supplemented with high-quality pellet food, along with moderated amounts of leafy greens and other fresh vegetables. Healthy guinea pigs can also enjoy small amounts of safe fruits as a special treat. So, is banana on the safe list? Read on to find out!

What Do Guinea Pigs Eat
Guinea pigs are herbivores and only eat plant material, with fresh hay the most important part of their domestic diet.

Can Guinea Pigs Eat Bananas?

Yes, banana is a safe fruit for most guinea pigs, but as with any fruit, only offer a small amount as an occasional treat.

What Are the Health Benefits of Bananas?

Bananas are high in potassium, fiber, antioxidants, and vitamin C, which are great for your piggies!

What Are the Potential Problems with Consuming Bananas?

As with most other fruits, it’s also high in sugar, which can lead to obesity and diabetes if overfed. It also can potentially cause digestive problems such as gas and bloating. Guinea pigs already suffering from obesity, diabetes, kidney disease, or digestive problems should avoid eating bananas.

What Is An Appropriate Amount of Banana to Offer?

If you want to give banana as your guinea pig’s special fruit treat, limit it to about one thin “coin” slice per week.


Bananas should be limited about to 10-15 grams a week. A good rule of thumb is to give no more than one thinly sliced “coin” over a week. So, for example, you could offer half a coin twice a week. Furthermore, if this is their first time trying it, offer an even smaller amount to make sure it doesn’t give them any tummy trouble!

Can They Eat the Banana Peel Too?

Yes, guinea pigs can eat a banana peel, or skin, although they might not be as interested in it. If you leave the peel on the banana slices, make sure it’s washed first.

What Fruit is Best for Guinea Pigs?

Guinea pigs can eat a variety of fruits without seeds. However, when feeding your guinea pig banana or other fruit, do so in moderation and only as a treat. You can feed them slices of fresh fruit, such as oranges, blueberries, mangos, pineapples, and kiwi. Your guinea pig should never eat avocado, which is poisonous thanks to the fruit’s persin, a fungal toxin.
