Vomiting, drooling, loss of appetite, lethargy, depression, increased thirst or urination, dehydration, decreased urination or lack of urination, acute kidney failure, and death in cats.
Asian Lily, commonly known as Asiatic Lily, is a true lily in the genus Lilium. True lilies are highly toxic to cats. Even small exposures may be dangerous, including chewing leaves or petals, licking pollen from the coat, or drinking water from a vase containing lilies.
The toxic principle responsible for lily poisoning in cats has not yet been identified, but the effect can be severe and rapid. Early signs may include vomiting, drooling, lethargy, and loss of appetite. Signs of kidney injury may develop later and can include increased thirst, increased urination, dehydration, decreased urination, or complete lack of urination.
Lily exposure in cats should be treated as a veterinary emergency. Early diagnosis and aggressive treatment, especially prompt decontamination and intravenous fluid therapy when appropriate, greatly improve the chance of survival. Dogs may develop gastrointestinal upset after lily ingestion, but cats are the species at greatest risk for life-threatening kidney failure.
Immediate Response to Lily Exposure
- Remove the Source: Take away any remaining plant material, flowers, pollen, or vase water immediately.
- Prevent Grooming: If pollen is on the cat’s coat, prevent the cat from licking it and contact a veterinarian for instructions on safe removal.
- Do Not Wait for Symptoms: Cats may appear normal at first, but kidney damage can develop later. Treat any suspected exposure as urgent.
- Seek Veterinary Care Immediately: Contact your veterinarian, an emergency veterinary clinic, ASPCA Animal Poison Control, or Pet Poison Helpline at once.
- Do Not Induce Vomiting Unless Directed: Vomiting may be part of treatment when exposure is recent, but it should be done only under veterinary or animal poison-control direction. Do not give hydrogen peroxide or attempt home decontamination unless specifically instructed by a veterinarian or animal poison-control professional.
- Special Warning for Cats: For this specific plant, the highest-risk animal is the cat, and hydrogen peroxide should not be treated as a harmless home remedy. ASPCA guidance indicates hydrogen peroxide is generally not advised in feline patients because it may not reliably cause timely vomiting and cats are more prone to gastritis or hemorrhagic gastritis. ASPCA also warns that hydrogen peroxide can irritate a cat’s stomach and esophagus.
Symptoms Requiring Emergency Care
- Early Signs: Vomiting, drooling, lethargy, depression, or loss of appetite.
- Kidney-Related Signs: Increased thirst, increased urination, dehydration, decreased urination, or no urination.
- Severe Signs: Weakness, collapse, worsening depression, acute kidney failure, or death if untreated.
Veterinary Treatment
- Early Decontamination: A veterinarian may induce vomiting, administer activated charcoal, bathe pollen from the coat, or perform other decontamination depending on the exposure and timing.
- Fluid Therapy: Cats exposed to true lilies often require hospitalization and intravenous fluid therapy to support kidney function.
- Monitoring: Bloodwork, urinalysis, hydration status, urine output, and kidney values may need to be monitored closely for at least 24 to 72 hours.
- Bring a Sample: If possible, bring a flower, leaf, photo, plant tag, or bouquet information to help confirm the plant identification.
