Is crimson flag lily safe for cats and dogs?
Toxic — the ASPCA lists crimson flag lily as a clear no for cats and dogs. The painful part for the pet is usually quick and intense; the right move is to keep it out of any room a pet roams unsupervised. 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. Pet Poison Helpline lists Kaffir lily (Hesperantha coccinea) as toxic to dogs and cats. The toxic principle is lycorine, an alkaloid found in all parts of the plant. Clinical signs include vomiting, drooling, retching, and gastrointestinal distress; large ingestions (particularly of the rhizomes) may cause low blood pressure, heart rhythm disturbances, weakness, and seizures. Unlike true lilies (Lilium), it does not cause acute kidney injury in cats.
