Nutrition Facts of Oranges

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 proteinsthere 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.




  • 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.


  • 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

Are oranges bad for guinea pigs? No, oranges are not bad for guinea pigs but in larger serving sizes they cause some problems. These are the most common risks that oranges cause 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 to Feed Guinea Pigs Oranges (Serving Size and Frequency)


Do guinea pigs like oranges? This is the first thing you need to know. Yes, guinea pigs like oranges because they are refreshing to them. Also, they like the texture and the fruity smell of an orange. That is why you need to be careful with the serving sizes when feeding guinea pigs with oranges.


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.


How to Prepare Orange for Your Guinea Pig?


  • Step 1 – Choose an orange that is ripe and not green or rotten. If the orange is not ripe it will be too acidic for your guinea pig. Any type of rotten food is out of the question.

  • Step 2 – As always, any fruit or a vegetable that you are planning to give your guinea pig needs to be washed. The same needs to be applied to oranges.

  • Step 3 – You can give guinea pigs orange peels but we don’t advise it because of pesticides that are commonly used in the world. Pesticides can sometimes be found in the peels (orange skin) and that is why it is better to remove all of it.

  • Step 4 – If your orange contains any seeds, please remove them as they can be a choking hazard for your cute 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.
