Safety status
What this means for your cat
Cats that bite a leaf get hit with microscopic calcium-oxalate needles, and the burning is immediate — most cats stop chewing on their own after one taste. Toxicity is local rather than systemic, but the pain is real, and persistent drooling or pawing at the mouth warrants a vet call.
What to watch for
Sudden, frantic pawing at the mouth and heavy drooling within minutes of a chew. Lips, tongue, and gums may look red or swollen. Vomiting and refusal to eat are common. Less commonly, swelling can extend to the upper airway — voice change, stridor, or labored breathing is rare but a true emergency.
Time window
Pain and drooling typically 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, any time drooling lasts more than an hour, swelling is visible, your cat won't eat or drink, or vomiting persists. Any sign of difficulty breathing or swallowing is an emergency — go immediately and don't wait.
First aid at home
Wipe any plant fragments out of the mouth with a damp cloth and offer cold water to drink. A small amount of milk or plain yogurt may help bind the oxalate crystals and ease the burning. Do not induce vomiting unless your vet specifically tells you to.
