Feeding Guinea Pigs Radishes

You can safely include radishes once per week for your guinea pig. Generally, you want to thoroughly wash them beforehand to remove dirt, debris, and pesticide residue (if they’re not organic).

A safe serving size is between half and one radish per guinea pig. In most cases, guinea pigs are fine biting pieces off the radishes, but if you’re worried, you can also chop them into fine pieces for easy consumption.

Guinea pigs can eat the root (which is what people tend to eat) and the leaves, so feel free to put both in the cage. Your guinea pig may not enjoy the taste of the root but love the leaves. It’s just like people, where some don’t like how it tastes.

Please remember you should never give a guinea pig cooked radish. Guinea pig digestive systems are not suitable for cooked foods.

Nutrients in Radishes

Vitamin C

Vitamin C is critical for your guinea pigs since they cannot make their own. Radishes are considered relatively high in Vitamin C. Vitamin C plays a crucial role in overall health, including natural healing.


Your guinea pig needs calcium for healthy bones, muscles, and nerves. Regular calcium intake means your guinea pig’s nerves function properly and blood clots appropriately if it becomes necessary.


Fiber is a regulator in the digestive system, whether you’re a guinea pig or a human. Fiber slows down the digestion of food, so every bit gives a little more nutrition since there is more time to digest it, among other benefits.

Potassium helps your guinea pig regulate the fluid levels in its cells. This action supports normal blood pressure, which in turn supports other bodily functions. Potassium is also important for muscle function.


Folate (B9) is critical to your guinea pig’s protein metabolism. Since proteins dictate what the body does, the right amount of folate helps the entire body. Folate is also critical for maintaining DNA and RNA.
