How to Feed Oranges To Guinea Pigs (Serving Size and Frequency)

These are the nutrients per approximately 6 oz of orange (one large orange):

  • A good amount of calories – 86.5 calories. For fruit, this amount is great and will provide more energy throughout the day (see carbs and proteins point below). Also, this caloric amount is not extremely high considering we are talking about fruit. So, the guinea pig will not get fat from oranges!


  • Carbs and proteins – there are 21.6 g of carbs and 1.7 g of protein in one big orange. These two are the main sources of energy for any organism to survive and fulfill any daily activities, even if it’s just resting without movements.


  • Low in fat – 0.2 g. With a low amount of fat, the bodyweight will not be affected and most importantly, the blood vessels will not be clogged so the guinea pig heart will work better too.


  • Fibers – 4.4 g. The fibers are always beneficial for good digestion. Without them, there is a chance of constipation and unhealthy bowel movements (irregular emptying).


  • Vitamin C – 163 %. With such a high amount of vitamin C, your guinea pig is surely safe from the dangerous scurvy disease. This disease starts when the cavies are lacking this vitamin because they don’t produce it naturally or store it in their bodies.


  • Thiamine – 11 %. This is the B1 vitamin and it turns the carbs into energy very fast.


  • Potassium – 10 %. The potassium helps in maintaining healthy blood pressure and balance of electrolytes and water in the body too. Without potassium, there is a risk of fatigue, constipation, and dehydration.


  • Vitamin A – 8 %. This is a strong antioxidant which will keep immunity in amazing health and it will protect it against free radicals that damage the lungs, liver, heart, skin – every organ.


  • Calcium – 73.6 g. This amount of calcium is too high for the guinea pig. When this mineral deposits in excessive amounts, there are serious urinary problems for the guinea pig.


  • Sugar – there is 17 g of sugar in one large orange. Of course, this means you can only serve oranges in only in moderate amounts because this is too much sugar for the cavy to digest!


  • Magnesium – 18.4 g. This mineral is keeping the muscles strong and healthy.

Risks to Consider When Feeding Oranges to Guinea Pigs

  • Urinary problems – The orange contains quite a lot of calcium. Fully grown guinea pigs will not benefit from calcium. Those mineral deposits create bladder and kidney stones, pain during urination and bloody urine too.


  • Bad digestion – Also, orange has sugars too. It contains beneficial nutrients like vitamin C, but precaution is needed because of the sugar. Sugar can cause painful digestion or bowel problems like a loose stool.

How Often and How Much Orange Is Good for My Guinea Pig?

Because of the sugar content and calcium as well, limit oranges to 2 times per week. Of course, do not give them a whole orange! A slice or two, or one thick big wedge is enough for the guinea pig to be delighted! Otherwise, there is a risk of urinary issues and bladder/kidney stones, as well as bad digestion and belly pains from the sugars in the orange.

Which Oranges Are Best for the Guinea Pig?

The tastiest and best types of oranges for your guinea pig are the Lychees, mandarin orange, as well as Clementine oranges. Of course, you can give the guinea pig a taste of any common orange you buy and consume yourself, as long as you pay attention to the serving sizes.

Can Guinea Pigs Eat the Orange Peel Too?

Yes, if your guinea pig munches on the orange peel it is completely safe and edible. Of course, the orange peel also contains vitamin C so there are benefits from it too for the guinea pig. However, avoid giving the cavy too much of the orange peel and focus more on the flesh fruit part. This is because the orange peel is rougher than the flesh and may irritate their mouth tissue while chewing it.
