Is Caucasian Lily toxic to cats?

Yes — caucasian lily is toxic to cats according to the ASPCA. Keep it well away from any cat that chews plants; reactions can be significant. 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.

Signs usually appear soon after chewing rather than hours later — watch for drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy after your cat has had access to caucasian lily.

Stay calm. Remove any plant from your cat's mouth and take the plant away. Note how much was eaten and when, and do not induce vomiting unless told to. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice; a leaf or photo helps the vet treat it correctly.
