Easter Lily
Lilium longiflorum · Liliaceae
How it looks
Easter Lily is a lily cultivar whose large pure-white trumpet flowers face sideways or slightly downward. The six petals curl back slightly and the flower is strongly fragrant; the leaves are dark green, narrow, and long, wrapping around the stem. It usually blooms in March and April.
Deadly — kidney failure from a small amount
This is among the most dangerous of all true lilies (Lilium). Every part — petals, leaves, pollen, even the vase water — is deadly, and a cat can die of acute kidney failure within 24–72 hours of ingestion.
If ingested

Guide for parents
The Easter lily arrives easily in spring as a bouquet or potted gift, but do not bring even a single stem into a home with a cat. It belongs to the true lily genus (Lilium) and is among the most dangerous lilies of all for cats. Even one petal or a single grain of pollen can lead to acute kidney failure.
True lilies versus lilies in name only
The Easter lily is a true lily — like the lily and the daylily — the kind that causes kidney failure in cats. By contrast, the common houseplant peace lily is a lily in name only; it's an entirely different plant that causes mouth irritation, not kidney failure. The nature of the risk is completely different, so first confirm which one you actually have.
How cats get exposed
Petals and leaves, the pollen, and even the vase water are all deadly. A cat can be poisoned just by brushing against the flower and later grooming the pollen off its fur, so keeping it up high is not enough. If it came as a gift, the surest move is to get it out of the house.
How symptoms progress
Signs usually begin 6–24 hours after ingestion with vomiting, loss of appetite, and lethargy. There's often a window where the cat seems to recover, while kidney damage quietly continues. By 24–72 hours, urine output drops sharply and kidney failure becomes visible — and at that stage it is very hard to reverse.
What to do right now
If there's any chance your cat touched or ate it, go to a 24-hour emergency vet immediately, even with no symptoms at all. The earlier IV fluid therapy begins, the better the odds of protecting the kidneys. With lily poisoning, how fast treatment starts is what decides survival.
Safer flowers instead
If you want spring flowers in a home with a cat, switching to confirmed-safe roses or gerbera daisies is the easier choice.
