Is Arisaema nepenthoides toxic to cats?

Yes — arisaema nepenthoides is toxic to cats according to the ASPCA. Keep it well away from any cat that chews plants; reactions can be significant. Arisaema species are toxic to cats and dogs. The ASPCA lists the closely related Arisaema triphyllum (jack-in-the-pulpit) as toxic, with insoluble calcium oxalates as the toxic principle; the genus, including A. nepenthoides, shares this chemistry. Ingestion causes oral pain and swelling of the mouth, tongue and lips, excessive drooling, difficulty swallowing and vomiting. Keep away from pets and consult a vet if chewed.

Ingestion causes oral pain and swelling of the mouth, tongue and lips, excessive drooling, difficulty swallowing and vomiting. Keep away from pets and consult a vet if chewed. Signs usually appear soon after chewing rather than hours later — watch for drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy after your cat has had access to arisaema nepenthoides.

Stay calm. Remove any plant from your cat's mouth and take the plant away. Note how much was eaten and when, and do not induce vomiting unless told to. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice; a leaf or photo helps the vet treat it correctly.
