Yes — and this is one of the most dangerous plants a cat can meet. Every part of an Easter lily, including pollen and vase water, can cause fatal kidney failure.

Also known as: Lilium longiflorum, White Lily, Trumpet Lily · Lilium longiflorum

What makes it toxic

An unidentified nephrotoxin concentrated in all tissues of true lilies (genus Lilium). Even tiny amounts — a few petals, two stamens or licked pollen from fur — can shut down the kidneys.

Warning signs to watch for

Early signs within 2–6 hours: drooling, vomiting, loss of appetite and depression. Within 12–72 hours these progress to increased thirst, urination changes, dehydration, tremors and kidney failure.

What to do if your cat eats it

This is a true emergency. Go to a vet or emergency animal hospital immediately even if the cat looks fine — treatment started early (aggressive IV fluids within 18 hours) can prevent kidney failure. Do not wait for symptoms.

Common questions

How little lily is dangerous for a cat?

Staggeringly little. Pollen groomed off the fur, a bite of a single leaf or even drinking the vase water has caused fatal kidney failure.

Are all lilies dangerous to cats?

True lilies (Lilium and Hemerocallis daylilies) are. Peace lily, calla lily and peruvian lily are not true lilies and cause only mild mouth irritation — but many owners cannot tell them apart, so treating any “lily” as an emergency is the safe rule.

Is Easter lily dangerous to dogs too?

Dogs get stomach upset from lilies but not the fatal kidney failure seen in cats. Still, avoid letting dogs chew them.
