Healthy Weight

Considering that pineapple is lower in fat and calories than other sweet fruits, you won’t need to worry about the guinea pig’s weight.

Pineapple contains magnesium, which will keep the heart muscle strong. Also, thiamin, known as the B1 vitamin, keeps the nerves healthy along with other muscles and the heart.

Guinea pigs cannot produce vitamin C naturally, so they must get it from food or other supplements. The good thing is that pineapple is very rich in vitamin C. Without vitamin C guinea pigs can get scurvy, a fatal disease that starts manifesting itself with a rough coat, loss of appetite, diarrhea, weight loss, internal bleeding, and weakness.

There are many vitamins and minerals in pineapple that will help with creating blood cells. One of them is vitamin K that will contribute to fast blood clotting. In case of injuries, when there is blood loss, this will be crucial. Vitamin B6 and iron can prevent anemia. Vitamin B6 boosts serotonin, the hormone of happiness, reduces anxiety, and helps with better sleep.


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 are able to cause different illnesses, early aging, and many other problems.

Risks to Consider When Feeding Pineapple to Guinea Pigs

Risks to Consider When Feeding Pineapple to Guinea Pigs

As beneficial as pineapple is to guinea pigs, it also poses certain health risks to them. Some of these risks are as follows:

Urinary Problems

The calcium in the pineapple can cause urinary problems for your guinea pigs. This mineral is crucial for forming strong bones, but only in the early stages of growth and development (baby guinea pigs).

If the guinea pig 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 guinea pigs. This is because the sugar in the pineapple can cause pain during digestion and cause diarrhea. The guinea pigs don’t digest sugars well, so keep this in mind when giving new foods to them.


There is an enzyme called bromelain in pineapples. This enzyme is most present in the stem and leaves of pineapples. Bromelain has many health benefits, but in large amounts, it has some side effects.

Some guinea pigs can be allergic to pineapples, and that usually happens due to bromelain. Some of the pineapple’s allergy symptoms are upset stomach, diarrhea, an increased heart rate, difficulties in breathing, vomiting, and so on.

Pineapple or any other fruit needs to be given to guinea pigs only occasionally as a treat. You can feed pineapple to them one or two times per week.

How Much Pineapple Can Guinea Pigs Eat?

Guinea pigs shouldn’t eat pineapple in large serving sizes. Guinea pigs are tiny animals with a sensitive digestive system, and giving them pineapples in large amounts can lead to serious stomach problems.

You can feed them only two to three small pieces of pineapple at once. Everything above that limit can cause serious problems. So, you need to be careful and combine pineapples with hay, water, and other fruits and vegetables.

Usually, pineapple is a very delicious and a loved treat for guinea pigs. In general, guinea pigs enjoy eating fruits, such as apples, nectarines, melons, mango, kiwi, blueberries, watermelon, strawberries, and many others.

Can Baby Guinea Pigs Eat Pineapple?

Baby guinea pigs shouldn’t eat pineapple because, during that period, they need a special diet. That special diet contains only the mother’s milk, alfalfa hay, and water. Alfalfa hay is important due to its calcium content, which is beneficial for guinea pigs’ growth. You can later slowly introduce them to some fruit and vegetables after a few weeks. Be sure to give them at first only a tiny piece of pineapple.
