Can Guinea Pigs Eat Potatoes

As a guinea pig owner, a common question that might come to your mind is whether or not guinea pigs can eat potatoes.

The short answer is no, guinea pigs should not be fed potatoes. These starchy vegetables can cause many health issues in your small pet.

Read on to find out why potatoes are not the best choice for guinea pigs.

Can Guinea Pigs Eat Potatoes?

No, potatoes are not safe for guinea pigs to consume. Let’s explore the reasons behind this.

Too Much Starch and Digestive Issues

Potatoes, like parsnips, are high in starch, which can be difficult for guinea pigs to digest. This could lead to digestive issues in your little pet.

Guinea pigs have sensitive digestive systems, which easily get upset by a change in their diet. Starch in potatoes may cause digestive problems like diarrhea or constipation in guinea pigs if consumed in large quantities.

Lacking Nutrients

Besides the potential toxicity, potatoes also lack the essential nutrients your guinea pig needs for a balanced diet. Guinea pigs require vitamin C, as they cannot produce it themselves. Unfortunately, potatoes don’t provide enough vitamin C to meet their needs.


Feeding potatoes to your guinea pig can pose a potential risk of toxicity. Potatoes contain glycoalkaloids, which might not represent a risk of teratogenicity in humans but can still be harmful to smaller animals like guinea pigs.

These compounds can cause adverse effects in your pet, such as nausea, vomiting, and diarrhea. To avoid this risk, always remove potato peels and avoid feeding your guinea pig raw, green, or sprouted potatoes.

Choking Hazards

Another issue with feeding potatoes to your guinea pig is the choking hazard. Whole potatoes or large chunks can get lodged in their throat and cause choking.

To minimize this danger, it is best not to feed raw or cooked potatoes to guinea pigs.

What Else to Avoid

You should also avoid feeding your guinea pigs processed food such as bread. Dairy products such as cheese, ice cream and yogurt. Nuts and seeds such as cashews, peanuts and pistachios. Food that is rich in sugar like honey. Garlic and onions are also bad for them.

  • Leafy greens: Spinach, kale, and romaine lettuce are all excellent choices. They provide essential nutrients without being too high in sugar.
  • Bell peppers: Red, yellow, or green bell peppers are a great source of vitamin C.
