Is snake's head iris safe for cats and dogs?
No — snake's head iris 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. Hermodactylus tuberosus is closely related to Iris and sits in the family Iridaceae. The ASPCA lists Iris species as toxic to cats, dogs, and horses, with the toxic principles being pentacyclic terpenoids (irisin, iridin, and irisine), which are most concentrated in the rhizomes and tubers. Clinical signs include salivation, vomiting, drooling, lethargy, and diarrhea; skin irritation may also occur on contact with the sap.
