Is johnston's cyrtosperma safe for cats and dogs?
Avoid for a pet household. Johnston's Cyrtosperma is ASPCA-listed toxic to both cats and dogs; even a small chew can drive a vet visit. Plenty of look-alikes on the non-toxic side of the list — see alternatives below. 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. Cyrtosperma johnstonii belongs to the Araceae family and, like all Cyrtosperma species, contains calcium oxalate raphide crystals throughout its tissues. Ingestion of raw material causes severe oral burning, mucosal irritation, vomiting, and gastrointestinal distress in cats, dogs, and humans. ASPCA classifies the Araceae family as toxic to cats and dogs. Cooking destroys the crystals in edible species, but C. johnstonii is not a recognised food crop.
