⚠️ Caution May be okay in small amounts or specific forms — read the details.

Cooked, plain potatoes are generally safe for guinea pigs in small amounts. However, raw potatoes, green potatoes, and potato skins contain solanine, a toxic glycoalkaloid that can cause digestive upset and neurological issues. Always ensure potatoes are fully cooked and unseasoned before offering them as an occasional treat.

⚠️ Emergency: Possibly — call your vet for advice.

💡 Why

Potatoes belong to the nightshade family, which produces solanine as a natural defense mechanism. This compound is concentrated in the skin, eyes, and green parts of the tuber. While small amounts of cooked white potato flesh are low-risk, the potential for toxicity from raw or green parts warrants caution.

🩺 What to do

  1. Never feed raw, green, or sprouting potatoes to your guinea pig.
  2. If you offer potatoes, boil or steam them plain without salt, butter, or spices.
  3. Remove all skins and discard any green or sprouted sections before serving.
  4. Limit potato intake to a small piece once or twice a week to prevent digestive issues.

❓ Common questions

Can guinea pigs eat potato chips?

No, potato chips are unsafe due to high salt, fat, and additive content, which can lead to dehydration and kidney strain.
