Which Lilies Are Toxic?

The following genera cause acute renal failure in cats: Lilium (Easter lily, Tiger lily, Stargazer lily, Asiatic lily, Oriental lily) and Hemerocallis (Daylily). NOT toxic: Peace lily (Spathiphyllum), Calla lily (Zantedeschia), and Peruvian lily (Alstroemeria) — these contain insoluble calcium oxalate crystals that cause oral irritation but not renal failure. The toxic principle in true lilies has not been conclusively identified — the nephrotoxin appears to be a water-soluble compound present in all plant parts.

Clinical Progression

0-2 hours: Vomiting, hypersalivation, depression, anorexia
12-24 hours: Polyuria (excessive urination) as renal tubules lose concentrating ability, followed by oliguria (decreased urine output)
24-48 hours: BUN and creatinine begin to rise, isosthenuria (urine specific gravity 1.008-1.012), renal tubular epithelial casts on urinalysis
48-72 hours: Anuric renal failure (no urine production), severe azotemia, hyperkalemia, death without hemodialysis

Emergency Treatment Protocol

Recent ingestion (<6 hours): induce emesis, administer activated charcoal. All cases: aggressive IV fluid diuresis (2-3× maintenance rate) for 48 hours minimum to maintain renal perfusion and flush nephrotoxin. Monitor urine output every 4 hours. If oliguria or anuria develops despite fluids, hemodialysis or peritoneal dialysis is the only treatment option — available at university veterinary teaching hospitals. Prognosis: >90% survival with treatment within 18 hours; <50% survival if treatment begins after 18 hours; near 0% survival once anuric renal failure is established.

🚨 If Your Pet Has Been Exposed

DO NOT WAIT for symptoms to appear. Contact your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435 immediately. Have your pet's weight, the substance involved, estimated amount consumed, and time of ingestion ready. The risk calculator above is an educational estimate only — individual animal responses vary based on age, breed, pre-existing conditions, and concurrent substance ingestion.
