Contact your veterinarian or an animal poison-control resource now, especially if any amount was chewed or swallowed.
Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.
Signs to watch for
Vomiting, lethargy, loss of appetite, and signs of kidney failure such as increased thirst and urination.
Escalation note
Ingestion of even small amounts of any part of the plant can cause acute kidney failure in cats. Contact a veterinarian immediately if ingestion is suspected.
What to watch for
Early signs: vomiting, inappetence, lethargy. As kidney injury develops: increased thirst and urination, then decreased urination. Untreated cases progress to acute kidney failure and death.
Time window
Onset of vomiting and lethargy is typically within hours; without treatment, acute kidney failure develops over the following days. ASPCA states that aggressive in-hospital treatment can prevent kidney injury, so the earlier the cat is seen, the better the prognosis.
When to call the vet
Call immediately — do not wait for symptoms. Any cat that has chewed any part of a lily, licked pollen off its fur, or drunk lily vase water is a veterinary emergency. Contact your veterinarian or ASPCA Animal Poison Control at (888) 426-4435 right away.
What this means for your cat
Japanese show lily is one of the most dangerous plants a cat can encounter. ASPCA notes that even very small ingestions — fewer than 1–2 petals, pollen brushed onto fur, or water from the vase — can cause acute kidney failure. Aggressive in-hospital treatment is the only reliable way to prevent permanent kidney injury.
