Can Guinea Pigs Eat Blueberries_

Guinea pigs are one of the most adorable plant-eating pets on the planet. These rodents absolutely love almost all types of veggies and fruits. They find small berry-like fruits especially tasty. Guinea pigs have lots of benefits from eating fruits as well, for example, they can get all the essential vitamins and minerals for their optimal health through fruits. In this article, we are going to talk about blueberries and guinea pigs. Now let’s take a closer look and see if guinea pigs can have blueberries in their diet.

Can guinea pigs eat blueberries? Guinea pigs can eat blueberries but only in moderation. Blueberries are healthy for the guinea pigs because they are rich in vitamin C and antioxidants but due to the sugar level and acidity, they need to be regulated. For guinea pigs, blueberries should be given in small serving sizes and only twice a week.

Guinea pigs need vitamin C in their daily diet. Since they can’t synthesize or store this vitamin by themselves, they need to receive it through the blueberries and other vitamin C rich foods. The one big disadvantage of blueberries is the amount of sugar in them because guinea pigs have trouble processing sugary foods. Sugar in general causes them digestion problems.

In the following sections, you will find out if blueberries are safe for guinea pigs and everything related to blueberries and guinea pigs including the risks, nutrition facts, serving size, and more. Let’s begin!

Are Blueberries Good for Guinea Pigs? | Health Benefits

Are Blueberries Good for Guinea Pigs Health Benefits

There are numerous benefits that blueberries can give to guinea pigs. The following are just some of them:


Vitamin C and the Scurvy Prevention

Guinea pigs need blueberries mainly for vitamin C, this is the primary benefit that they get from blueberries. With vitamin C, guinea pigs can have healthy mouth and teeth, good digestion, and more importantly, vitamin C prevents a disease called scurvy. This disease comes from vitamin C deficiency and can cause massive problems to guinea pigs. The problem is that guinea pigs don’t make or synthesize this vitamin themselves, nor can they store it properly and this is why they need an external vitamin C source. So, if your cavy lacks vitamin C, treat it with blueberries but naturally in moderation.


Antioxidants and Improved Immune System

Blueberries are packed with important antioxidants that greatly improve the well being of guinea pigs. Antioxidants protect guinea pigs from free radicals which cause aging and different diseases. The main antioxidants in blueberries are called anthocyanins, this antioxidant is responsible for main health benefits in blueberries.


Low in Calories

Even though blueberries contain sugar they are very low in calories. One positive thing is that guinea pigs will not consume caloric food which can cause them digestive problems. Their whole diet mainly consists of light and watery foods and it should stay like that for the most part. On the side note, blueberries also have a lot of fiber which can be a double-edged sword as it can also improve digestion, and at the same time, too much of it causes constipation.


Blood Pressure Regulation

There is significant evidence that blueberries can regulate the blood pressure in humans, the same can be applied to guinea pigs as well. Blueberries in general are amazing fruit for heart-related conditions.

Risks to Consider When Feeding Blueberries to Guinea Pigs

You need to remember that even though blueberries are healthy for you, they might be too much for the guinea pig. Yes, they have vitamin C, antioxidants, and many other benefits but in large serving sizes the amount of sugar in this fruit comes with some risks for guinea pigs. You can avoid most health issues from blueberries if you serve it sparingly and only two times a week. Now let’s dive deeper into the potential risks for guinea pigs.


Diarrhea and Digestive Problems

The side-effects of too many blueberries can be diarrhea and digestive issues. Guinea pigs are very adorable and they can convince you to give them almost a handful of blueberries! You have to learn to say no to your pet. Just imagine how bad their tummy would be after too many blueberries before you give them any more of them. Due to a lot of fiber in them, serious problems can arise in their intestines. Not just intestines, but the overall digestion will be more sensitive, the guinea pig will have gasses and bloating, or even belly pains and discomfort.


Sugar Content in Blueberries

If the guinea pig consumes too many blueberries or too often, they will ingest too much sugar as well. The risk of excess sugar for guinea pigs is that they can easily become obese, develop different digestion complications, and there is a risk of getting diabetes.


Acidic Taste | Mouth Problems

Blueberries can also irritate the delicate tissues in the mouth of a guinea pig. The oral health of guinea pigs is already fragile as it is, so why provoke it often with acid fruits? Their mouth might get sore from too many blueberries and this is why that type of food needs to be used sparingly.


Serving Size and Frequency of Blueberries for Guinea Pigs

Serving Size and Frequency of Blueberries for Guinea Pigs

Considering the risks above it is important to know are guinea pigs allowed to eat blueberries every day or in what amounts can you feed blueberries to guinea pigs. We will answer all of these questions and more in the following sections below.


Can Guinea Pigs Have Blueberries Every Day?

Guinea pigs can’t eat blueberries every day because of the sugar content in them which can be harmful to guinea pig’s health. You probably have thought since guinea pigs are herbivores, they can eat most fruits almost every day. This is certainly not true as fruits cannot be consumed by guinea pigs every day even though they are healthy and nutritious for humans. For guinea pigs, any fruit with a high amount of sugar is not recommended to be in their diet very often.

So, how often can guinea pigs eat blueberries? Twice per week should be even more than enough. After all, there are other fruits and vegetables with vitamins and minerals for guinea pigs as well. Having a variety in their diet will positively impact their overall well being.

How Many Blueberries Can a Guinea Pig Eat a Day

When you feed to guinea pigs blueberries it’s important to know how many of them is enough. The trick with blueberries is that they have a lot of vitamin C that cavies need, but on the other hand they also have a lot of sugar and this makes things a little bit complicated.

So, blueberries may be healthy and tasty, but the guinea pig is not supposed to have more than 2 to 3 whole blueberries in one day. First of all, the acidity in blueberries may cause soreness in the mouth of a guinea pig, so 2 to 3 small blueberries are more than enough.


Do Guinea Pigs Like Blueberries?

So, do guinea pig eat blueberries gladly? Guinea pigs absolutely like blueberries and they enjoy eating them.

So, during that period baby guinea pigs shouldn’t eat blueberries. After that period you can introduce blueberries and other fruits and vegetables to them. It’s important to remember that if you are planning to give your guinea pig blueberries for the first time, do it slowly and gradually.
