Is Lily Toxic to Dogs and Cats?
Toxic - Danger
True lilies (Lilium species) and daylilies (Hemerocallis) are extremely toxic to cats and can cause acute kidney failure. All parts of the plant are toxic, including the pollen, petals, leaves, and even the water in the vase. Dogs are less sensitive but can still experience GI upset.

Why Is Lily Toxic?
Toxic Compounds: Unknown nephrotoxin (lily-specific)
What Happens in the Body: The toxin causes rapid kidney tubular damage in cats. Without treatment, acute kidney failure develops within 24-72 hours and can be fatal.
Signs of Lily Poisoning
If your pet has been exposed to Lily, watch for these symptoms:
- Vomiting (within hours)
- Loss of appetite
- Lethargy and depression
- Drooling
- Decreased urination (sign of kidney failure)
- Seizures in severe cases
What To Do If Your Pet Ate Lily
For cats: This is an EMERGENCY - seek immediate veterinary care
Remove any plant material from your cat's fur or mouth
Bring a sample of the plant to the vet if possible
Do not wait for symptoms - early treatment is critical for cats
Time is essential - kidney damage can begin within 24-72 hours
Veterinary Treatment
Cats require immediate aggressive treatment including decontamination, IV fluids for 48-72 hours minimum, and kidney function monitoring. Prognosis is best with treatment within 6 hours of ingestion.
Information for Veterinarians
ANY exposure in cats should be treated as an emergency. Even grooming pollen off fur or drinking vase water can be fatal. Dogs typically only experience GI upset.
Frequently Asked Questions
Are all lilies toxic to cats?
True lilies (Easter, Tiger, Asiatic, Daylily) are highly toxic. Peace lilies and Calla lilies cause different, less severe reactions (mouth irritation, drooling).

Yes, with immediate treatment. Cats treated within 6 hours have a much better prognosis. Delayed treatment often results in permanent kidney damage or death.
