Are Cedar Shavings safe for Guinea Pigs?

✓ Sources checked by the Eaoae Safety Review · 2026-10-28 · Based on 6 sources

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

No, cedar shavings are not safe for guinea pigs. The aromatic oils in cedar can irritate their sensitive respiratory systems and skin. While chewing small amounts is rarely fatal, the fumes pose a significant risk to their health.

🚨 Emergency: Yes — contact your veterinarian immediately.

💡 Why

Cedar contains phenolic compounds, such as plicatic acid, which are toxic to small mammals. These volatile oils can cause respiratory distress, skin irritation, and liver damage in guinea pigs. Unlike aspen, which is safe, cedar is explicitly discouraged by veterinary experts for use as bedding.

🩺 What to do

  1. Immediately remove all cedar shavings from the guinea pig's cage.
  2. Replace the bedding with a safe alternative like aspen shavings or paper-based bedding.
  3. Monitor your guinea pig for signs of respiratory distress, such as wheezing or sneezing, and consult a vet if symptoms appear.
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

Is aspen a safe alternative to cedar?

Yes, aspen shavings are widely considered the safest wood-based bedding for guinea pigs because they lack the toxic aromatic oils found in cedar.

Can I use cedar if I only use it as a scent?

No, even low levels of cedar fumes can accumulate in a small enclosure and harm your guinea pig's lungs over time.

What if my guinea pig already chewed on cedar?

If they only nibbled a small piece, monitor them closely for a few days. If they show signs of illness, contact your veterinarian immediately.
