ABSTRACT
Toxic Principle and Mechanism of Action The common Easter lily, the tiger lily, Asiatic or Japanese lily, and the numerous Lilium hybrids and day lilies (Hemerocallis spp.) are toxic to cats causing kidney failure that can prove to be fatal.1-5 The toxin responsible for the nephrotoxicity of lilies has not been identified. All parts of the plants are poisonous to cats, but especially the flowers. Deaths have been reported in cats after ingestion of only two leaves. Dogs, rats, and rabbits were not affected after they were fed high doses of Easter lily experimentally.3
