Is Peony Toxic to Cats?
Also known as: Common Peony, Garden Peony, Paeonia lactiflora · Paeonia lactiflora
What makes it toxic
Paeonol and paeoniflorin, phenolic compounds concentrated in the roots and present throughout the plant, which irritate the digestive tract.
Warning signs to watch for
Drooling, vomiting, diarrhea and mild lethargy within a few hours of chewing foliage or flowers.
What to do if your cat eats it
Remove access, offer water and monitor. Call your vet only if vomiting persists, blood appears, or the cat refuses food the next day.
Common questions
Are cut peonies in a vase risky?
The same mild toxicity applies, so keep bouquets where a cat cannot chew the blooms or drink the water.
Is the root more dangerous than the flowers?
Yes — the root bark carries the highest paeonol levels, but a house cat rarely digs that deep. Flowers and leaves are the usual exposure.
My cat sniffed the bouquet — fine?
Completely. Only actual chewing or eating matters with this plant.
