In the spring, lilies become more common in households as potted plants or in bouquets. According to Michigan State University Extension's Grower Guide, Easter lilies are the third most important flowering pot-plant grown in the United States , with 10 million to 11 million plants produced annually. Unfortunately, several types of lilies can be deadly to cats. Easter lily, tiger lily, rubrum lily, Japanese show lily, some species of day lily, and certain other members of the Liliaceae family can cause kidney failure in cats.

Within only a few hours of ingestion of the lily plant material, the cat may vomit, become lethargic, or develop a lack of appetite. These signs continue and worsen as kidney damage progresses. Without prompt and proper treatment by a veterinarian, the cat may develop kidney failure in approximately 36-72 hours.

All parts of the lily plant are considered toxic to cats, and consuming even small amounts can cause severe poisoning. Cat owners should be aware of the dangers of lily ingestion and remove them from their cat's access.

Lilies that have been shown to cause kidney failure in cats include:*

Easter lily (Lilium longiflorum)
Tiger lily (Lilium tigrinum)
Rubrum lily (Lilium speciosum)
Japanese show lily (Lilium lancifolium)
Day lily (Hemerocallis species)
