ASPCA National Animal Poison Control Center Warns Cat Owners of Lily Dangers.

Easter LilyAs spring approaches, lilies will 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 l0 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 of the 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 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. For this reason, cat owners should avoid exposing their cats to plants of the Liliaceae and Hemerocallis family.

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

Lilium longiflorum

Tiger Lily

Lilium tigrinum


Lilium speciosum

Japanese Show Lily

Lilium lancifolium

Glory Lily

Lilium Superba
