Drooling, vomiting, diarrhea, and lethargy.
Ingestion of the rhizomes or leaves can cause gastrointestinal irritation. Please contact your veterinarian if you suspect your cat has ingested any part of this plant.
Calmly remove any plant matter from the cat's mouth and fur, and pick up remaining plant pieces so there's no second helping. If sap is on the skin or around the mouth, rinse the area with water. Don't induce vomiting on your own. Call your vet or ASPCA Poison Control to decide whether the cat should be seen.
Most common: drooling and vomiting, sometimes with diarrhea and lethargy. ASPCA notes oral and GI irritation as the dominant pattern. With a rhizome ingestion the GI signs tend to be more pronounced and persistent. Watch for refusal to eat, hiding, or repeated vomiting.
Signs can appear as soon as 2 hours after ingestion. Most cats recover within 24–48 hours with supportive care (fluids, anti-nausea medication if needed); rhizome ingestions can take longer to resolve.
Call your vet or ASPCA Poison Control (888-426-4435) if drooling lasts more than a couple of hours, if vomiting or diarrhea persist beyond 12–24 hours, or if your cat appears lethargic or stops eating. Call immediately if you saw the cat chew on the rhizome (bulb-like underground stem) — that's the most toxic part.
Cats that bite a Butterfly Iris leaf usually get away with mild GI upset — the irritating pentacyclic terpenoids (zeorin, missourin, missouriensin) are concentrated in the rhizomes, not the foliage on display. A cat digging into a pot or pulling up a freshly cut bulb is the bigger concern. ASPCA lists it as toxic to cats; signs are typically uncomfortable but rarely dangerous.
