Cat Ate a Lily: The 72-Hour Kidney Failure Timeline, Emergency Treatment, and Which Lilies Actually Kill
A cat that eats a true lily — Easter lily, tiger lily, Asiatic lily, stargazer, daylily — can be dead from kidney failure within 72 hours. The toxin targets the tubular cells of the kidneys with a precision that has no antidote. What determines survival is almost entirely timing: IV fluids started within 18 hours of ingestion can prevent kidney damage entirely. After kidney failure is established, the prognosis shifts from guarded to very poor. This guide gives you the hour-by-hour timeline, the exact emergency steps, the definitive species list of which lilies kill and which don't, and what to expect from treatment.
