What are lilies?

Lilies, that is, Lilium (true lily) and Hemerocallis (day lily) species, are poisonous to cats and cause kidney failure. Other flowers and plants that are also called ‘lilies’(e.g. peace lily) may also be toxic, but are not discussed in this leaflet. The toxic chemicals and the mechanism of lily poisoning are unknown but all parts of the plant are thought to be toxic including the leaves, flowers and pollen. Ingestion of even a small quantity (e.g. less than one leaf or part of a fl ower), as well as grooming pollen from the fur, is enough to potentially cause severe poisoning in a cat.
