Members of the true lily family (Lilium and Hemerocallis) have been shown to cause kidney failure in cats. Some examples of true lilies include Easter lilies, tiger lilies, rubrum or Japanese showy lilies, and day lilies. Even a small amount of exposure (a few bites on a leaf, ingestion of pollen, etc.) may result in kidney failure. Cats often vomit within a few hours of exposure and stop producing urine within 72 hours. Cats who receive quick treatment (intravenous fluids for two days) have a good prognosis. Lilies are common in holiday flower bouquets and arrangements, as are popular lily-like holiday flowering bulbs, such as amaryllis, which can also be toxic to pets.
