What this means for your cat

Cats that chew peony leaves, stems, or — most concentrated — bark, can develop GI distress from the plant's paeonol. ASPCA describes signs as vomiting, diarrhea, and depression; severity is generally mild to moderate, and this is not a cyanide-style stone-fruit emergency.

What to watch for

Vomiting and diarrhea are most common; lethargy and a 'depressed,' low-energy demeanor often follow. Cats may also drool from the bitter taste.

Time window

Onset is usually within hours of ingestion; uncomplicated GI signs typically resolve in 24-48 hours with rest and bland feeding. Exact paeonol timing is not well documented.

When to call the vet

Call your vet if vomiting or diarrhea persists more than a few hours, your cat refuses food and water, or the lethargy looks severe. A same-day appointment is normally appropriate; ER care is rarely needed.

First aid at home

Per Pet Poison Helpline, get the cat away from the plant and gently wipe plant material from in and around the mouth with a damp cloth. Never induce vomiting in a cat.

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.
