Are Melons Good for Guinea Pigs? | Health Benefits

Health Benefits of Guinea Pigs Eating Melons

There are numerous health benefits that can be attributed to melons. Some of them are the following:

Healthy Weight

Because melon is low in fat and calories for a fruit, the little guinea pig will not get chubby or be at risk of obesity. Guinea pigs love to eat and they sometimes don’t know when to stop eating, so it’s important to provide them with a small amount of food that is low in fat and calories. This way the weight of the guinea pig won’t be affected.

Healthy Cardiovascular System

Your guinea pig’s cardiovascular system will stay healthy due to the zero amount of cholesterol in melons. Also, blood vessels will stay healthy because of the low amount of fat that will not clog them in the guinea pig’s organism.

There is vitamin K in melons that contributes to healthy blood clotting. This means if an injury happens (internal or external), there will be less blood loss.


Vitamin A acts like one of the best antioxidants out there. It removes the free radicals that create damage to the body, such as early aging. This vitamin will also prevent many different diseases that can harm the health of guinea pigs.

Vitamin A improves eye health and overall immunity as well. Many internal organs will be healthier with this vitamin such as the heart, lungs, and kidneys above all.

Prevention from Scurvy

Vitamin C is a must-have vitamin for guinea pigs. Without this vitamin, they can get a disease called scurvy. The symptoms of this disease are swollen joints, internal bleeding, oral problems, loose stool, no appetite, and a rough coat. So it’s crucial to provide them with foods rich in vitamin C, and melons are one of them.

Healthy Organs and Muscles

B6 vitamin, which can be found in melons, has numerous benefits for guinea pigs. It cleanses the liver, cures anemia, removes aches and pains, improves eyesight, and reduces stress and anxiety. This vitamin is good for muscles, and guinea pigs will sleep like a baby because vitamin B6 also reduces stress.

There is also some magnesium in melons, which is mostly known for reducing any pains and aches and for protecting the overall health. The magnesium keeps all muscle tissues in good health, without pain or soreness, and this goes for the heart muscle as well.

Is Melon Poisonous to Guinea Pigs? | Possible Risks

Is Melon Poisonous to Guinea Pigs

Let’s see what are the possible risks of giving your guinea pigs melon.

Bad Digestion

Melons might be delicious and hydrating, but they also have sugars. Guinea pigs don’t digest sugars well, and their stomachs are not designed for types of foods high in sugar and fat. If a guinea pig consumes more sugar, it will get loose stool or tummy pains.

Urinary Problems

The melon also contains some calcium, this mineral is necessary for very young guinea pigs that need to grow and develop. But, once the guinea pig is fully grown, calcium becomes harmful to them as it can cause many problems in the urinary tract of an adult guinea pig.

This mineral, if it deposits in the urinary tract will create kidney or bladder stones. Also, it may cause painful urination, blood in the urine, or persistent urinary infections.

Bacteria Risk

Unfortunately, melons and especially cantaloupe melons can contain some harmful bacteria such as salmonella on their surface. That’s because their rind is rough, and bacteria can easily get trapped there during growth and transport. So, when eating melons or feeding melons to guinea pigs, you need to be very careful.

It’s important to buy fresh melons that don’t have any damage on their rind. Always wash the melon thoroughly with water. Also, it’s essential to wash your hand, desk, and knives to decrease the contamination risk of the melon flesh. Lastly, always keep melons in the refrigerator.

Serving Size and Frequency of Melon for Guinea Pigs

Can Guinea Pigs Have Melon Every Day?

Guinea pigs shouldn’t eat melon every day because of the sugar and calcium content in them. They can eat only hay and pellets every single day, but fruits and vegetables need to be moderated.

Also, they need a versatile diet with different fruits and vegetables. It’s recommended to feed melon to the guinea pig 2 to 3 times per week. This way, you don’t need to think a lot about the possible risks we mentioned above.

Can Guinea Pigs Eat Whole Melon?

Guinea pigs can’t eat a whole melon because that quantity can be harmful to their stomach. As we have already said, there is a lot of sugar and calcium in melons, so you need to limit the servings to a few tiny melon pieces or cubes. For example, 2 to 3 very small cubes are enough. There are also other fruits that you can introduce in your guinea pig’s diet, such as watermelon, blueberries, strawberries, kiwis, grapes, and so on.

The cantaloupe melon is also known as a rockmelon, sweet melon, or spanspek. This fruit is very nutritious, delicious, and beneficial for health. Guinea pigs can eat cantaloupe melon. The most beneficial thing about cantaloupe melon is that this melon is rich in vitamin C (an essential vitamin for guinea pig’s health).

Nevertheless, due to the sugar and calcium content, cantaloupe melon should be fed to guinea pigs only in small serving sizes and not every day. Also, cantaloupe melon is known as the riskiest melon when we talk about bacteria on their surface, especially salmonella. So, be careful when feeding cantaloupe melons to guinea pigs.

Guinea pigs can eat honeydew melon, but also only in moderation. Honeydew melon in some parts of the world is also known as a green melon. It has many nutrients that are beneficial to guinea pigs. However, if we compare honeydew melon with cantaloupe melon, we can say that cantaloupe melon is a healthier version for guinea pigs. This is because cantaloupe melon has double the amount of vitamin C and around 60% more vitamin A than a honeydew melon.

Be careful when preparing honeydew melon for guinea pigs. Give them only fresh honeydew melon and wash it well with water before serving. There is also the possibility of bacteria presence and different pesticides that can be harmful to guinea pigs.

But, it’s essential to remember to only feed them in small quantities, a few slices, 2-3 times per week.

People tend to eat bitter melons cooked because cooking tames their bitter and strong flavor. But, as we already know, guinea pigs can’t eat any cooked food and this includes cooked bitter melon.

Feed canary melons to guinea pigs only in moderation and choose ones that are mature with bright yellow skin.

It’s full of vitamins, various minerals, low in fat and calories, and contains no cholesterol. However, you shouldn’t feed Galia melons to guinea pigs often. Always give them small serving sizes due to the calcium and sugar content in them.

Can Guinea Pigs Eat Winter Melon?

Winter melon has a specific taste. When immature, this fruit is sweet, but when it matures, it obtains a mild flavor. Guinea pigs can eat winter melon, as this melon has some potential health benefits for guinea pigs. It’s low in calories and fat and contains some essential vitamins and minerals. Also, because of calcium, sodium, and sugar content, winter melon needs to be fed only in moderation.

Can Guinea Pigs Eat Melon Seeds?

Guinea pigs shouldn’t eat melon seeds because these seeds are a choking hazard for them. This is why we recommend removing melon seeds before giving this fruit to guinea pigs, even if they are small and soft. Only then will you be sure that nothing will happen to your guinea pigs, and you can watch calmy how they enjoy eating melons.

Can Guinea Pigs Eat Melon Peel / Melon Skin?

Can Guinea Pigs Eat Melon Peel Melon Skin

Guinea pigs love the flesh part of the melon without the seeds. Guinea pigs can sometimes chew on the melon skin as well. The skin of melon is not the nutrient-rich part, but it helps them keep their teeth in good shape and can prevent overgrowth of the teeth.

But, as we have already said, melon skin can contain some bacteria such as salmonella and pesticides, which can be very harmful to guinea pigs and even lead to death. So, if you’re willing to give them the melon peel, be sure to wash it thoroughly with water.

Honeydew melon skin or Galia melon skin is softer to guinea pigs and is easier to clean. However, you need to be careful with cantaloupe melon skin. This skin is problematic as it can contain more bacteria and pesticides due to the imperfections on the skin (rougher in texture).
