Colorado State University Veterinarians Warn Feline Owners About Lily Toxicity

With Easter approaching, Colorado State University’s veterinary critical care specialists are reminding cat owners that several types of lilies are toxic to kittens and cats.

Lilies that are toxic to cats include the Easter lily, tiger lily, Rubrum lily, stargazer lily, Japanese show lily and day lily.

Lilies that are not toxic include lily of the valley and peace lilies.

Signs that a cat has ingested toxic lilies include vomiting, lack of appetite and lethargy.  Symptoms usually occur within 24 to 48 hours. Without immediate treatment, the feline’s kidneys may fail within 72 hours.

All parts of the lily plant are toxic and consuming even small amounts can be lethal.  

Colorado State University veterinarians suggest keeping toxic lilies out of the house or ensuring that the flowers are well outside of a cat’s reach.

If a cat does ingest lilies, contact your veterinarian or take the cat to an emergency veterinary clinic immediately. Early intervention can be life-saving and prevent costly veterinary care.

Lilies are not known to be toxic to other companion animals.

Colorado State University’s veterinarians are also professors in the College of Veterinary Medicine and Biomedical Sciences.
