Cats face a true emergency with this plant — true lilies in the Lilium genus can cause fatal kidney failure even from tiny exposures, including chewing leaves, licking pollen off fur, or drinking from the vase water. There is no 'mild' case of true-lily ingestion in cats; treat any contact as urgent and don't wait for symptoms.
Earliest signs are decreased activity, drooling, vomiting, and loss of appetite, often within 0 to 12 hours of contact. By 12 to 24 hours look for increased urination then dehydration; by 24 to 72 hours untreated cats develop kidney failure and may stop urinating altogether.
Early GI signs appear within 0 to 12 hours; signs of kidney damage follow at 12 to 24 hours; untreated kidney failure typically develops within 24 to 72 hours and is often fatal. Cats started on IV fluid diuresis within 18 hours of exposure have the best prognosis.
Call immediately. Any time you see your cat chew, lick, or even brush against this plant, contact your vet or ASPCA Animal Poison Control at (888) 426-4435 the same hour. Treatment started within 18 hours has the best chance of preventing irreversible kidney damage.
Bring the plant — or a clear phone photo of it — with you to the clinic so the vet can confirm the species. Do not wait for symptoms before seeking care.
