Questions about Peony

Are peonies toxic to cats?

Yes, peonies (Paeonia officinalis) are toxic to cats. All parts of the plant contain paeonol, which causes gastrointestinal distress if ingested. The toxicity is considered mild to moderate — serious outcomes are uncommon, but any ingestion warrants monitoring.

What symptoms will my cat show after eating a peony?

The most common signs are vomiting, diarrhea, and lethargy. Cats may also drool from the plant's bitter taste and appear low-energy or 'depressed.' Symptoms typically begin within a few hours of ingestion and usually resolve within 24–48 hours with rest and bland feeding.

What should I do if my cat ate part of a peony?

Move your cat away from the plant and gently wipe any plant material from in and around the mouth with a damp cloth. Do not induce vomiting in cats. Call your vet or the ASPCA Animal Poison Control Center at (888) 426-4435 for guidance — a same-day vet visit is normally appropriate, but ER care is rarely needed.

When should I take my cat to the vet after peony ingestion?

Call your vet if vomiting or diarrhea persists more than a few hours, your cat refuses food and water, or the lethargy appears severe. Most cases are mild and resolve at home, but a same-day appointment is a reasonable precaution given that exact paeonol toxicity timing is not well documented.

Are peonies toxic to dogs?

Yes, peonies (Paeonia officinalis) are toxic to dogs. All parts of the plant contain paeonol, which can cause vomiting, diarrhea, and depression if ingested.

What symptoms will my dog show after eating a peony?

Signs typically begin within hours of ingestion and include vomiting, diarrhea, and a lethargic or 'depressed' demeanor. Larger ingestions — especially of bark or roots where paeonol concentrates — can produce more substantial GI upset. Symptoms generally resolve within 24–48 hours with supportive care.

What should I do if my dog ate a peony?

Get your dog away from the plant and gently wipe any plant material from in and around the mouth with a damp cloth. Do not induce vomiting unless your veterinarian specifically instructs you to. Call the ASPCA Animal Poison Control Center at (888) 426-4435 or your vet for guidance.

Which part of the peony plant is most dangerous to dogs?

Paeonol is present throughout the entire plant, but it concentrates in the bark and roots, meaning those parts pose the greatest risk for more severe GI upset. Even ingestion of petals or leaves can cause vomiting and diarrhea, so all parts should be treated as hazardous.
