Can Guinea Pigs Eat Pineapple?

Can Guinea Pigs Eat Pineapple

Is there anything better in the summer months than a nice bowl of fruit salad? Or even better, pineapple chunks! Everyone loves pineapple – sweet, refreshing, watery, and versatile. We eat it fresh and raw, or in desserts as addition, in ice creams or smoothies and much more. When warmer months approach, we all crave for some refreshing pineapple, right? But, can our lovely guinea pigs enjoy this delicious fruit? Let’s find out.

Can guinea pigs eat pineapple? Yes, guinea pigs can eat pineapple. However, this fruit is very sugary, so try to give this to the cavy as a treat and not as regular food. The stomach of the guinea pigs cannot digest high amounts of sugar or too often, and this will result in stomach pains or loose stool if sugar is given in excess. Also, it is not a good idea at all to feed the guinea pig canned pineapple. Usually, every canned fruit is full of added sugars and chemicals needed for the processing. Just imagine the tummy pains the cavy would have if it ingests loads of sugar and processed pineapple fruit from a can!

It is awesome news that guinea pigs can eat pineapple, even if just rarely as a treat or in small amounts. This fruit has many health benefits, but also it has some risks along the way – we will explain everything about pineapple in the sections below.

Health Benefits of Guinea Pigs Eating Pineapple

  • Healthy weight – don’t worry, your guinea pig won’t get fat or chubby, pineapple doesn’t contain many calories.


  • Healthy cardiovascular system – the heart and the cardiovascular system will work perfectly fine because this fruit is low in fat. Pineapple also contains magnesium, which will keep the heart muscle strong.


  • Scurvy prevention – guinea pigs cannot produce vitamin C naturally, so they must get it from food or from other supplements. Without vitamin C they won’t be safe from getting scurvy, a fatal disease that starts manifesting itself with a rough coat, loss of appetite, diarrhea, weight loss, internal bleeding, and weakness.


  • Healthy blood and blood cells – the pantothenic acid in the pineapple will help with creating blood cells, and the vitamin K will contribute to a fast blood clotting (in case of injuries when there is blood loss, this will be crucial).


  • Antioxidants – the manganese in the pineapple is a very strong antioxidant and will keep the immune system strong to fight off most diseases. Mainly, it will keep the health in good shape because it fights free radicals which cause illnesses, early aging, and many other problems.

Nutrition Facts of Pineapple

Here are the nutrition information for raw pineapple, 100 g (3 oz):

  • A moderate amount of calories – 50 calories. The pineapple is not too high in calories and this means it is not fattening too.


  • Carbs and proteins – pineapple is quite rich in carbs, 13.1 g and it has just a small amount of proteins, 0.5 g. But, these amounts of carbs and proteins are enough, considering this is a fruit.


  • Low in fat – 0.1 g. Another reason why the weight of the guinea pig will not be changed.


  • Vitamin C – 80 %. Pineapple is very rich in vitamin C, the only crucial vitamin a cavy must have to survive. Without this, they are prone to the disease called scurvy which is fatal for guinea pigs.


  • Vitamin K – 1 %. This vitamin helps with the creating of the prothrombin, the protein that clots the blood.


  • Sugar – 9.8 g. This is too much sugar and might cause painful digestion if you feed your guinea pig too much pineapple.


  • Thiamin – 5 %. Also known as B1 vitamin, this keeps the nerves healthy along with muscles and the heart.


  • Vitamin B6 – 6 %. This vitamin can prevent anemia. But most importantly, it boosts the serotonin, the hormone of happiness, and it reduces anxiety too. Also, it can help with better sleep.


  • Pantothenic acid – 2 %. This is known as vitamin B5 and it converts fats, proteins, and carbs into energy. Also, it helps with the creation of blood cells.


  • Calcium – 13 mg. This mineral forms strong bone tissues, but for grown and fully developed guinea pigs it is not very good.


  • Magnesium – 12 mg. This mineral removes pains from the muscles and keeps the muscle tissues strong, this means the heart muscle will be in good shape too. Also, this mineral prevents diabetes, migraines, and anxiety too.


  • Manganese – 46 %. The strongest antioxidant there is, the manganese fights the free radicals that cause serious damage and many diseases to the body.

Risks to Consider When Feeding Pineapple to Guinea Pigs

  • Urinary problems – The calcium in the pineapple can cause urinary problems for your guinea pig. This mineral is crucial for forming strong bones, but only in the early stages of growth and development (young guinea pig pups). If the cavy is fully grown, this mineral will damage its urinary tract and create bladder or kidney stones. Other risks are blood in the urine, pain during urination or infections in the urinary tract.


  • Digestion problems – This fruit is very sugary and this is definitely not good for the guinea pig. So, we confirmed they can eat pineapple, but as a treat and not too much or too often. This is because the sugar in the pineapple can cause pain during digestion and diarrhea too. The guinea pigs don’t digest sugars well, so keep this in mind when giving new foods to them.
