Are Cucumbers Good for Guinea Pigs

Healthy Weight

The cucumbers won’t make your guinea pig chubby and are light for the digestion as well. They are mainly water, very low in sugar, calories, and in fat. They are overall amazing for weight control as they provide satiety, which means your guinea pigs will eat less. If you notice that your guinea pig is chubby, introducing cucumbers might be a good idea.


Is there anything better than a refreshing watery veggie, especially in hot summer days? Or after a caloric meal? Cucumber is a fresh delight for guinea pigs and it will give them hydration that they desperately need during the summer.

Cardiovascular System and Blood Vessels

The cucumber is low in fat and has zero cholesterol. This is extremely beneficial for the cardiovascular system and blood vessels. Also, there is vitamin K in cucumbers that contributes to healthy blood clotting, and with a deficit of this vitamin, the organism is prone to long periods of bleedings during injuries or other health issues.


In cucumber, there are nutrients like vitamin A, which acts as an antioxidant and protects the guinea pig’s body from free radical damage. With antioxidants, there is less risk of diseases in general. They also keep the immune system in good shape. Also, vitamin A prevents and fights inflammation, and makes vision, lungs, kidneys, skin, heart, and brain stay in good health.

Prevention From Scurvy

Cucumber has vitamin C, which is essential for guinea pigs. They don’t produce it naturally and can’t store it either. This is not a very high amount of vitamin C but it is enough to keep the cavies safe from scurvy. This disease is fatal for them and manifests with the following symptoms: internal bleedings, bad oral health, swollen joints, diarrhea, rough coat, loss of appetite, and more.

Risks to Consider When Feeding Cucumber to Guinea Pigs

Risks to Consider When Feeding Cucumber to Guinea Pigs

Urinary Problems

There is about 14 mg of calcium per 100 g of cucumber. This is not that much, but it needs precaution because adult guinea pigs don’t really benefit from calcium. This mineral piles up in their urinary tracts and creates bladder or kidney stones. If not treated, this will cause blood in the urine or painful urination which can lead to renal (kidney) failure and even death.


Cucumbers may become bitter in taste and this happens because of the presence of the toxin called cucurbitacin. This toxin is produced naturally by cucumbers and some studies have shown that cucurbitacins can be harmful to both humans and guinea pigs. The more cucurbitacins are in cucumbers the more bitter they are in taste and more poisonous to guinea pigs.

Some of the symptoms of this food poisoning are diarrhea, vomiting, and stomach pain. In order to prevent cucumber poisoning in guinea pigs, be sure to taste the cucumber before giving it to the guinea pig and also fed them only fresh cucumbers.

Some Risk of Diarrhea and Stomach Aches

Cucumber is very tasty to guinea pigs, but it is very watery and if fed in large quantities without other food varieties it can upset their fragile belly. So try to serve cucumbers along with another food for the guinea pigs because the stomach digests watery foods better when they are combined with something more caloric.
