Is Jack-in-the-Pulpit Toxic to Cats?
Also known as: Arisaema triphyllum, Indian Turnip, Bog Onion · Arisaema triphyllum
What makes it toxic
Insoluble calcium oxalate raphides, most concentrated in the corm (root). When tissue is chewed, the needle-like crystals pierce the lining of the mouth, tongue and throat.
Warning signs to watch for
Immediate burning and drooling, pawing at the mouth, reluctance to swallow and possible vomiting. Swelling severe enough to affect breathing is rare in cats, which usually stop chewing quickly.
What to do if your cat eats it
Rinse the mouth with water and offer water or a little milk. Watch for an hour; call your vet if drooling and vomiting continue or the tongue swells visibly.
Common questions
Is the raw root the dangerous part?
Yes. The corm holds the densest crystal load — historically it was only eaten after thorough cooking. Leaves and the flower stalk cause milder irritation.
Can Jack-in-the-pulpit kill a cat?
It is very unlikely. The pain stops most animals after one chew, and the oxalates are the insoluble type that irritate rather than poison. Airway swelling is the only serious scenario.
