The Daily Requirement For Guinea Pigs

Guinea pigs need a lot of Vitamin C and roughage in their diet. This is why food items like Timothy Hay and Vitamin C supplements for added quantities are considered essential for these rodents. The roughage in food is going to help the digestion in these small creatures while intake of Vitamin C is essential because these animals do not make their Vitamin C.

Bananas are indeed rich in fiber, but that is different from roughage, which refers to the hardness of the food, making it more caloric to burn. Bananas are a soft fruit and although it has fiber, they can be a peril if given every day. This fruit also has Vitamin C, which is an integral part of the guinea pig’s diet, but is it enough?

Why Is A Banana Not A Daily Food Item For Guinea Pigs


Bananas cannot be fed daily to your guinea pig because of the high sugar levels. The amount of sugar in 100 grams of bananas is 12.2 grams, which is more than what a guinea pig can eat in a day. High sugars can give them an upset stomach and also promotes obesity and diabetes.

A very serious issue related to overdosing on your guinea pig with bananas is kidney function. Guinea pigs have weak kidneys when compared to mammals. While potassium is good for kidneys, feeding too much of it to guinea pigs and other rodents will put a burden on their kidneys and they can suffer immensely.

This is because these animals will not be able to process bananas and their kidney will burn out while trying to filter the excess potassium. Due to these two factors, bananas are not an ideal daily item for guinea pigs.

Can Guinea Pigs Eat Banana Peels

Banana peels might sound like a good idea to feed your guinea pig, especially since they need to get roughage. However, we cannot recommend that you feed banana peels to your guinea pig. These peels are bulky and may cause impaction in the intestines, which causes constipation.

Peels are a good alternative to sugary fruit, but they will not give any nutrition to the guinea pig so why not replace it with another food that offers more Vitamin C and roughage that guinea pigs can enjoy more and benefit from at the same time?

Feeding Size And Preparation

Start any new food item for your guinea pig in a small amount. The introductory dose should be a tiny portion so that the guinea pig’s reactions can be measured. If your guinea pig pet likes the taste of it, you can keep bananas on the list of occasional foods for them.

If your pet pig does not have any obesity issues or diabetes, a single slice of banana every two weeks can be a good snack. Since these little animals like to nibble on food all day, they can enjoy an occasional feed, but if they are overweight or have kidney issues, then do not feed this fruit to them at all.

The health of your guinea pig pet will determine how much of this fruit is acceptable. If they have developed a kidney disorder, which is common in these creatures, it is best to stay away from bananas. However, if they do not have any such issues, then a slice of banana twice a month is acceptable for them. Alternatively, see Can Guinea Pigs Eat Apples?
