Guinea pigs are small and adorable and require a diet to remain healthy. Guinea pigs need tons of fiber in their diet and a good amount of vitamin C, among other vitamins and nutrients. Like most pets, some foods are healthy for guinea pigs to eat, and there are some that you should never feed your guinea pig. But what about pineapples? Can you feed your guinea pig pineapples?

Yes, you can feed your guinea pig pineapples, but only in very small amounts. Guinea pigs should avoid eating any citrus fruit. While pineapple is not considered a citrus fruit, it does have some similarities. Pineapple is low in natural sugars when compared to other fruits like strawberries. However, pineapple still has enough natural sugars and other nutrients that can cause health issues for your guinea pig if you feed them pineapples too often. 

If you decide to feed your guinea pig some pineapple, only use freshly cut pineapple and only give them one or two small chunks of pineapple. It would be best if you never feed your guinea pig pineapple more than once per week. Furthermore, you never feed your guinea pig pineapple skin, pineapple leaves, or pineapple core, as these can cause digestive issues or pain if ingested.


As you continue to read this article, we will be going in-depth about the benefits of feeding your guinea pig pineapple. Afterward, we will list the potential dangers of feeding your guinea pig pineapple. Finally, we will discuss how you should prepare pineapple for your guinea pig and talk about how much and how often you can feed your guinea pig pineapple.

The Benefits of Feeding Guinea Pigs Pineapple

When feeding your guinea pig any fruit, you should always feed them fruit in moderation. Fruit is high in natural sugars, which can cause some health issues if they overeat. However, fruit also comes with a ton of vitamins and nutrients that your guinea pig will need to stay healthy.

Pineapple is not only safe if fed to your guinea pig in small amounts and in moderation, but pineapple provides several health benefits. The benefits of feeding some pineapple to your guinea pig include:

  • Strengthening The Immune System – Pineapples have beta-carotene, usually found in orange fruit and vegetables. Pineapples also contain a bunch of vitamin C. Both vitamin C and beta-carotene help strengthen the immune system. This means that feeding your guinea pig some pineapple every now and then can help prevent some common health risks for guinea pigs.
  • Improving Heart Health – Pineapple, like most fruit, is low in fat. Fat can block arteries and cause major issues for the heart and its ability to pump blood throughout the body. Pineapple also has high levels of magnesium, which has tons of benefits. However, possibly the most crucial benefit of magnesium is its ability to strengthen the heart muscle, which will improve its ability to pump oxygen-rich blood throughout the body. 
  • Pineapple Helps Prevent Illness And Disease – Vitamin C is possibly the most important vitamin you want your guinea pig to consume. Vitamin C helps strengthen the immune system, which will help your guinea pig fight off common health issues. Furthermore, the high magnesium levels in pineapples will help by further strengthening the immune system and strengthening the heart muscles. Magnesium is a natural antioxidant and helps your guinea pig’s immune system fight off free radicals, which can cause significant illnesses like cancer. Magnesium has another potential side-effect in which it helps prevent aging
  • Pineapples Help Improve Blood Clotting – Pineapples contain a healthy amount of vitamin K. Vitamin K is a coagulant and will help your guinea pig’s blood form clots. While blood clots are usually seen as bad, blood clotting helps form scabs and stop wounds from bleeding. So in the unfortunate circumstance where your guinea pig injures itself and bleeds, vitamin K will come to the rescue and help seal the wound faster.

The Potential Dangers of Feeding Your Guinea Pig Too Much Pineapple

Guinea pigs have a sensitive digestive system. This is because they are small creatures that have small organs. With that said, it is easy to provide too many nutrients for your guinea pig. Food like spinach and Brussel sprouts are healthy for your guinea pig but are packed with tons of nutrients and need to be fed in moderation. You can say the same thing for pineapples, but for a slightly different reason.

Pineapples are fruits, and pineapples also have a good amount of certain vitamins and nutrients. All of the benefits we listed above are true when it comes to feeding our guinea pig pineapples. However, those benefits can quickly turn into downsides if you feed your guinea pig too much pineapple or if you feed them pineapple too often. 

While vitamin C is an essential part of your guinea pig’s diet, too much can lead to some adverse effects. Too much vitamin C can lead to diarrhea, which can lead to dehydration. Too much vitamin C can also lead to nausea, vomiting, and digestive cramps.

Pineapples also contain calcium. Guinea pigs need a good amount of calcium while growing up. Calcium helps improve bone strength and promotes healthy bone growth. Once your guinea pig reaches adulthood, they will still need some calcium in their diet. However, too much calcium will lead to crystallization in your guinea pig’s urine. The crystallization of calcium in urine will cause your guinea pig’s urinary tract issues. Too much calcium can lead to the development of bladder, kidney, and phosphate stones. Furthermore, an overabundance of calcium can stop your guinea pig from urinating altogether. This is very bad as it can be fatal if not treated.

Furthermore, pineapples have a bunch of natural sugar in them. While the amount of sugar in pineapple is relatively low when compared to other fruits, it is still enough to cause some unfavorable side effects in your guinea pig. A guinea pig’s digestive system is not able to digest large amounts of sugar. Too much sugar in your guinea pig’s diet can lead to diarrhea and obesity. Diarrhea can lead to dehydration, while obesity can lead to diabetes. 

What Parts of a Pineapple Can I Feed My Guinea Pig?

When you want to give your guinea pig a piece of pineapple as a treat, you should only feed them the flesh of the pineapple. You should never feed your guinea pig the skin, core, or leaves of a pineapple. 

The pineapple leaves have tiny thorns on them, which can get caught in your guinea pig’s throat, esophagus, or digestive tract. The thorns will cause irritation and can be difficult to remove or pass.

The skin of pineapple is hard, coarse, and is usually coated in pesticides to ward off pests and wax to help preserve it. Furthermore, pineapple skin also has small thorns, which will cause the same issues as the thorns on pineapple leaves. 

The core of a pineapple is also a no-go. While the core of a pineapple is not toxic or harmful to your guinea pig, it is very tough. Therefore, if your guinea pig eats some pineapple core, it is unlikely that they will pass it without any complications like gut impacting or stomach pain.

How To Feed My Guinea Pig Pineapple

When feeding your guinea pig pineapple, you will want to prepare it properly. You will want to stay away from tanned or darker pineapples. Some producers will add additional chemicals or additives to help preserve the pineapple. Furthermore, you should avoid feeding your guinea pig pineapple juice and canned pineapples due to the additional preservatives added to the pineapple.

Make sure you are choosing a ripe and ideally organic pineapple. You will then want to skin the pineapple, remove the core, and then slice the pineapple into small chunks. Only serve your guinea pig raw pineapple. When you slice the pineapple, you will be able to see small sections where the pineapple will form a triangle that touches the core and the skin. These “pineapple triangles” are the perfect measurement for how much you should feed your guinea pig. Feed them one or two of these “triangles” per week maximum. 

If you get a fresh pineapple for your guinea pig, you will most likely be eating the vast majority of the pineapple so that it does not go to waste. With that said, if you are feeding your guinea pig pineapple, make sure you also like pineapple.

Final Thoughts

Pineapples, like most fruits, make for the perfect treat for your guinea pigs. However, all fruit has a lot of natural sugars in them and should only be fed to your guinea pig once or twice a week. With that said, pineapples have some pretty good benefits for your guinea pig. Just be sure to prepare the pineapple properly and not feed them too much.
