Is Leopard Lily Toxic to Cats?
Also known as: Panther Lily, Tiger Lily, Lilium Pardalinum · Lilium pardalinum
What makes it toxic
An unidentified nephrotoxin present in all tissues of true lilies (genus Lilium). Tiny amounts — a leaf bite, groomed pollen or vase water — can shut down a cat’s kidneys.
Warning signs to watch for
Drooling, vomiting, loss of appetite and depression within 2–6 hours, progressing over 12–72 hours to increased thirst, dehydration, tremors and kidney failure.
What to do if your cat eats it
Emergency. Go to a vet or animal ER immediately even if the cat looks fine — aggressive IV fluids started early can prevent kidney failure. Do not wait for symptoms to appear.
Common questions
Is my leopard lily a true lily?
It may not be — the name is also used for a spotted dumb cane (Dieffenbachia) and other plants. But if it is Lilium pardalinum, it is deadly to cats, so identify it before it enters a cat home.
How little true lily harms a cat?
Staggeringly little — pollen groomed off fur, one leaf bite or vase water has caused fatal kidney failure.
What if it turned out to be the Dieffenbachia version?
That plant causes painful mouth irritation rather than kidney failure — serious but far more survivable. A vet call sorts out the exposure either way.
