Several types of lilies can be deadly to cats

Lilies are commonly found 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 crop grown in the United States, with 10 to 11 million plants produced annually. Unfortunately, several types of lilies can be deadly to cats. Easter lily, tiger lily, rubrum, 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, 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 will develop kidney failure in approximately 36-72 hours.

All parts of these lilies are considered toxic to cats and consuming even small amounts can cause severe poisoning. If there is a lily in your home, there is always the chance that your cat could be accidentally exposed.

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

Common names | Scientific names
Easter lily | Lilium longiflorum
Tiger lily | Lilium tigrinum
Rubrum | Lilium speciosum
Japanese show lily | Lilium lancifolium
Day lily | Hemerocallis species
