Can guinea pigs eat blueberries? The simple answer is yes. Blueberries can be a great addition to a healthy guinea pig diet.
However, just like humans, guinea pigs need a well-rounded diet to truly thrive. Imagine surviving off of blueberries alone!
Guinea pigs should only be given blueberries—or any kind of fruit—in moderation.
Let’s take a closer look at the guinea pig diet to discover how often you should feed your piggy blueberries, and what these treats have to offer your furry friend.
What Is A Natural Guinea Pig Diet?
In the wild, guinea pigs are herbivores. They eat plants that naturally grow in their environment, such as grass, leaves, flowers, hay, and various fruits and vegetables.
They especially love foods that are rich in vitamin C, as their bodies cannot produce it on their own.
Both wild and domestic guinea pigs’ diets consist primarily of timothy hay. Domestic guinea pigs should also be fed guinea pig pellets to round out their diet and ensure they’re getting all the nutrients they need.
Guineas should also be fed a mixture of vegetables daily, but fruit (and some veggies) should only be given in moderation, one or two times per week.
Fruit has a lot of sugar, so we don’t recommend feeding it to your guinea pig daily.
What Are Blueberries?
I love sitting outside with a bowl of fresh blueberries and a book, soaking in the summer sun. Sometimes I even share with my dog!
The temptation to feed blueberries to our guinea pigs is totally understandable—they’re delicious! But are blueberries good for guinea pigs?
Well, blueberries are high in both vitamin C and sugar.
Vitamin C is vital for your guinea pig’s health. They don’t produce it on their own, and if they aren’t fed foods that are rich in vitamin C, they can develop scurvy. If the deficiency is bad enough, they can die.
However, too much sugar can be detrimental to your guinea pig’s health. They may get a stomach ache, gain too much weight, or even develop diabetes.
Alternatives To Blueberries
Luckily, there are a ton of healthier foods that are rich in vitamin C. Vegetables like spinach, broccoli, and kale are a better source of vitamin C than blueberries. They also have additional nutrients to keep guinea pigs healthy and happy.
But on the whole, blueberries aren’t bad for guinea pigs, though they must be fed in moderation. At most, one or two blueberries can be given once or twice a week.
Remember, guinea pigs are tiny animals! Their portion sizes are very different than ours.
Are Blueberries Good For Guinea Pigs?
The only advantage we can be completely sure of at this point is their vitamin C content.
Are Blueberries Bad For Guinea Pigs?
A guinea pig who eats too many blueberries is prone to stomach problems, diarrhea, and diabetes.
The main problem with blueberries is their high sugar content. Dried and frozen blueberries can contain additives that aren’t good for your guinea pig, so we recommend only feeding them fresh berries.
If you feed your guinea pig one or two fresh blueberries once or twice a week, you shouldn’t run into any problems.
Keep in mind that if you’re feeding your guinea pig other fruits, you may want to feed blueberries less often, so that they aren’t getting too much sugar.
If you do notice any changes in your guinea pig’s behavior after they’ve eaten blueberries, consult your veterinarian to be safe.
What Fruit Can Guinea Pigs Eat?
Guinea pigs love their fruit! Here are some fruits you can try feeding your guinea pig in moderation:
Which Fruit Is Toxic To Guinea Pigs?
The following fruits are toxic and should never be fed to guinea pigs:
- Stone fruit
Guinea pigs should not be fed frozen fruit or seeds.
In addition, fruits that aren’t on this list aren’t necessarily safe. Before feeding a new fruit to your guinea pig, do your research to ensure it’s okay for them to eat!
If your guinea pig eats a toxic food by mistake, contact your veterinarian for help.
Do Guinea Pigs Like Fruit?
Yes, guinea pigs love fruit! It’s like candy for them.
However, no one should eat candy all the time, or they’ll be unhealthy—and likely get a stomachache!
When it comes to whether or not a specific guinea pig will like blueberries, it depends on their tastes, and how picky they are.
For example, most of the guinea pigs in my life have loved snacking on fruit. But one especially fussy pig wouldn’t even touch a blueberry, even while his buddies were all busy munching on their treat!
The only way to truly know if your guinea pig likes blueberries is to offer them one.
Can Guinea Pigs Eat Blueberries?
Next time you’re munching on a fruit salad, feel free to give a delicious blueberry to your guinea pig! Chances are, they’ll love the treat.
As with most fruits, guinea pigs enjoy blueberries in moderation.
They can be given a blueberry or two occasionally, once or twice a week at most.
If guinea pigs are fed blueberries too often, the excess sugar can be detrimental to their health.
Fed in moderation, blueberries can be a yummy treat that’s rich in vitamin C.
