My cat ate Easter Lily - what should I do?
Lilium longiflorum
Potentially toxic
Contact your veterinarian or an animal poison-control resource now, especially if any amount was chewed or swallowed.
Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.
Signs to watch for
Vomiting, lethargy, loss of appetite, and signs of kidney failure such as increased thirst and urination.
Escalation note
Extremely dangerous; ingestion of even small amounts can lead to acute kidney failure and death. Contact a veterinarian immediately if ingestion is suspected.
What to watch for
Early signs are vomiting, drooling, lethargy, and loss of appetite. As kidney injury sets in, expect increased thirst and urination, then reduced or absent urination if the kidneys fail.
Time window
Vomiting and lethargy typically begin within 0–12 hours; kidney failure usually develops within 24–72 hours of exposure if treatment is delayed.
When to call the vet
Call your vet or ASPCA Animal Poison Control (888-426-4435) immediately for any suspected exposure — chewing a leaf, biting a flower, drinking the vase water, or licking pollen off fur all count. Aggressive treatment within 18 hours dramatically improves the chance of survival; delay beyond that is often fatal.
What this means for your cat
Easter Lily is one of the most dangerous houseplants for cats — every part of the plant, including the pollen and the vase water, can trigger acute kidney injury. Cats are the only species known to be affected, and outcomes depend almost entirely on how quickly treatment begins.
