Is caucasian lily safe for cats and dogs?
Avoid for a pet household. Caucasian Lily 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. As a true Lilium species, Lilium monadelphum is severely toxic to cats (ASPCA confirmed, genus Lilium). All parts of the plant — including leaves, petals, pollen, stem, and water from cut stems in a vase — can cause acute renal failure in cats, frequently fatal within 24–72 hours unless treated as an emergency. Even small pollen quantities groomed from fur are lethal to cats. Also harmful to dogs and horses in significant quantities. This lily must never be grown where cats can access it.
