Pet ingestion lookup
My cat ate Calla Lily - what should I do?
Zantedeschia aethiopica
Potentially toxic
Contact your veterinarian or an animal poison-control resource now, especially if any amount was chewed or swallowed.
Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.
Signs to watch for
Oral irritation, intense burning and irritation of the mouth, tongue and lips, excessive drooling, vomiting, and difficulty swallowing.
Escalation note
Symptoms are generally localized to the mouth and gastrointestinal tract. Please contact your veterinarian or a pet poison control center if ingestion is suspected.
First aid at home
Wipe plant fragments from the mouth with a damp cloth and offer cold water. A small amount of milk or plain yogurt may help bind the oxalate crystals and reduce the burning. Do not induce vomiting unless your vet directs it.
What to watch for
Intense pawing at the mouth and heavy drooling within minutes of a chew. Look for redness or swelling of the lips, tongue, and gums; vomiting; refusal to eat; and head-shaking. Rarely, swelling extends to the back of the throat — voice change or labored breathing means it has gone serious.
Time window
Pain and drooling start within minutes of biting the plant. Most cases settle in a few hours to 24 hours with supportive care; airway swelling, when it occurs, can develop unpredictably.
When to call the vet
Call your vet, or ASPCA Poison Control at (888) 426-4435, if drooling lasts more than an hour, you see visible swelling, your cat won't eat or drink, or vomiting persists. Any sign of difficulty breathing or swallowing is an emergency — go immediately. Mention the plant by name; the team can rule out 'true lily' (Lilium/Hemerocallis) toxicity quickly.
What this means for your cat
Calla lily isn't a 'true lily' — it doesn't cause the kidney failure that Easter or tiger lilies do in cats. It's an Araceae plant with calcium-oxalate raphides, so a chew triggers immediate mouth pain rather than a systemic crisis. Painful, but not the lily emergency many owners fear.
