What should I do if my cat ate Peony?

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. Call your vet if vomiting or diarrhea persists more than a few hours, your cat refuses food and water, or the lethargy looks severe.

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.
