Guinea pigs are amazing cute little pets, and ours at Piggy Playground brings so much happiness into our lives. We just love hearing them squeak, and watching them zoom around their cage when it is feeding time.
As owners, we always want to share our favorite foods with our furry friends. Since guinea pigs are vegetarians, it is easy to assume that any vegetable in our kitchen is safe for them. A very common question we get asked is: Can guinea pigs eat potatoes?
If you are wondering whether you can share a slice of potato with your cavy, this guide is for you. Understanding their dietary needs helps you create a loving environment for them and avoid dangerous mistakes.

THE SHORT ANSWER: CAN THEY EAT POTATOES?
The answer is a strict no. You should never feed ordinary white potatoes to your guinea pig.
Unlike many other vegetables that are safe in moderation, potatoes pose a serious health risk to guinea pigs. They contain toxins that can be fatal, and their nutritional makeup is completely wrong for a guinea pig’s digestive system. While we humans love them mashed, baked, or fried, they should be kept far away from your pet’s cage.
WHY POTATOES ARE UNSAFE
There are two main reasons why potatoes are on the “do not feed” list: toxins and starch.
Solanine Toxicity Potatoes, specifically raw ones, contain a natural toxin called solanine. This is an alkaloid poison found in the skin and the flesh, with much higher concentrations in green potatoes or sprouted eyes. While humans cook potatoes to reduce these levels (and because our bodies are larger), even a small amount of solanine can be very dangerous for a small animal like a guinea pig. It can damage their nervous system and digestive tract.
Starch and Digestion Even if we ignore the toxins, potatoes are incredibly high in starch and carbohydrates. Guinea pigs have a sensitive digestive system designed to process high-fiber grass and hay, not dense starch. Feeding them starchy foods can lead to serious digestive upsets, including bloating and weight gain. In severe cases, it can disrupt their gut flora, leading to stasis, which is a life-threatening condition where the gut stops moving.
WHAT ABOUT SWEET POTATOES?
We often get asked if sweet potatoes are an exception. The answer is yes, but with a lot of caution. Sweet potatoes belong to a different plant family and do not contain solanine. Technically, a guinea pig can eat a tiny amount of raw sweet potato without being poisoned. However, they are still extremely high in sugar and starch. Feeding them sweet potato regularly can lead to obesity and diabetes. It is best to avoid them or only offer a tiny cube as a very rare treat, but there are much healthier options available.
WHAT HAPPENS IF YOUR GUINEA PIG EATS A POTATO?
If your guinea pig accidentally eats a small piece of potato dropped on the floor, don’t panic, but do monitor them closely. Watch for signs of solanine poisoning or digestive distress, which can include:
- Lethargy or weakness
- Diarrhea or soft stools
- A bloated belly
- Disinterest in food
If you notice your guinea pig isn’t eating, or sits in the corner alone a lot more than often, make sure to take it to a vet asap as these are signs of illness.
HEALTHY ALTERNATIVES
Feeding your guinea pig the right diet is crucial for their happiness and well-being. Instead of risky starchy vegetables, stick to crunchy, vitamin-rich options.
- Bell Peppers: Green/yellow Bell peppers should be fed daily as these are a great source of Vitamin C.
- Leafy Greens: Romaine lettuce, cilantro/coriander, and parsley are favorites that are safe to feed.
- Treats: If you want to give them something special, we recommend feeding your guinea pig some treats that are high in vitamin c. Ours love the Oxbow vitamin c supplements, and HayPig’s Nom Noms (UK only).
The Importance of Hay and Water
Hay is the foundation of a guinea pig’s diet. Timothy hay is an excellent choice. It is high in fiber, which helps maintain their digestive health. Make sure to provide fresh hay daily.
Water is equally important. Provide clean, fresh water always. Change the water daily to keep it clean. Offering both hay and water ensures that your guinea pig stays hydrated. This combination supports their overall well-being and helps prevent urinary tract issues.
With the right foods and fresh water, your guinea pig will thrive and enjoy a happy life!
