Everyone loves pineapple, this sweet, refreshing, watery, and versatile fruit is loved by many. When summer approaches, we all crave some refreshing like pineapple. But, can our lovely guinea pigs enjoy this delicious fruit, and is pineapple safe for guinea pigs? We all already know that there are some foods that guinea pigs can’t eat, so let’s find out what is the case with pineapple.

Can guinea pigs eat pineapple? Guinea pigs can eat pineapple, but only occasionally. This fruit contains a lot of sugar, so try to feed them pineapple only as a treat and not as regular food due to possible stomach problems. However, there is also a huge amount of vitamin C in pineapple, which is very beneficial for guinea pigs.

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 some risks along the way. We will explain everything about pineapple and guinea pigs in the following sections below. Let’s begin!

Is Pineapple Good for Guinea Pigs? | Health Benefits

Is Pineapple Good for Guinea Pigs Health Benefits

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. This means that pineapple is not a fattening fruit. Still, feed guinea pigs pineapple only in small amounts, and they won’t get fat or chubby.


Healthy Cardiovascular System

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.


Scurvy Prevention

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.


Healthy Blood and Blood Cells

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.


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


Healthy Muscles

Magnesium removes cramps and keeps the muscle tissues strong. Also, this mineral prevents diabetes, migraines, and anxiety too.

Risks to Consider When Feeding Pineapple to Guinea Pigs

Risks to Consider When Feeding Pineapple to Guinea Pigs

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 as well. The guinea pigs don’t digest sugars well, so keep this in mind when giving new foods to them.


Allergies

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.

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.

In general, guinea pigs enjoy eating fruits, such as apples, nectarines, melons, mango, kiwi, blueberries, watermelon, strawberries, and many others.

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 pig’s 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.

Also, you need to have in mind the bromelain enzyme is especially high in the pineapple core. It may cause diarrhea, vomiting, and other symptoms we mentioned above, this is why we suggested not to feed guinea pigs with pineapple core.
