Is amorphophallus maximus safe for cats and dogs?
No — amorphophallus maximus is toxic to cats and dogs. Keep it well away from any pet that chews plants; reactions can be significant. This classification follows the ASPCA Toxic and Non-Toxic Plant List, the most widely used reference for companion-animal plant safety in the US and the standard most UK vets cite as well. Amorphophallus maximus, like all members of the genus and the Araceae family, contains insoluble calcium oxalate raphides in corm, leaf and stem. The species is not individually listed by the ASPCA, but the ASPCA classifies directly-listed aroids (e.g. jack-in-the-pulpit, Arisaema) as toxic via insoluble calcium oxalates; treat it as toxic to cats and dogs. Chewing causes oral burning, intense drooling, swelling and vomiting. Keep away from pets and verify with a vet if ingested.
