⛔ Unsafe Known to be harmful or toxic. Keep it away from your pet.

No, rhubarb leaves are not safe for guinea pigs. They contain high levels of oxalic acid, which can cause kidney damage and other serious health issues if ingested. You should keep guinea pigs away from any part of the rhubarb plant except the cooked stems, which are also generally avoided due to acidity.

🚨 Emergency: Yes — contact your veterinarian immediately.

💡 Why

Rhubarb leaves contain significant concentrations of calcium oxalate crystals and oxalic acid. When guinea pigs chew on the leaves, these compounds can irritate the digestive tract and potentially lead to kidney stones or failure. Unlike the stems, which are often cooked and have lower acid levels, the leaves are highly toxic to small mammals.

🩺 What to do

  1. Immediately remove any rhubarb leaves from your guinea pig's cage or enclosure.
  2. If you suspect your guinea pig has eaten rhubarb leaves, contact your veterinarian immediately for advice.
  3. Monitor your guinea pig for signs of distress, such as lethargy, loss of appetite, or changes in urine output.
Important: this is for reference only and is not veterinary advice. If your guinea pig may have eaten or touched something dangerous, contact your veterinarian immediately.

❓ Common questions

Can guinea pigs eat rhubarb stems?

It is best to avoid feeding rhubarb stems to guinea pigs as well, because they still contain oxalic acid, which can be harmful to their kidneys over time.

How much rhubarb leaf is toxic?

Even small amounts of rhubarb leaves can be dangerous for small animals like guinea pigs, so it is safer to assume any ingestion is a risk and seek veterinary help.

Are rhubarb plants safe to have in the house?

Yes, as long as the guinea pig cannot reach the leaves or stems. Keep the plant out of reach or in a room the guinea pig does not access.
