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.
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.
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.
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.
