Oriental Lily

Yes, Oriental Lilies (Lilium orientalis) are extremely toxic to cats. Every part of the plant is dangerous — even pollen on the coat or a sip of vase water can trigger acute kidney failure. There is no safe level of exposure.

Early signs appear within 6–12 hours and include vomiting, excessive drooling, lethargy, and loss of appetite. As kidney damage develops over 24–72 hours, watch for changes in urination volume, excessive thirst or refusal to drink, and worsening vomiting and dehydration.

Wipe any pollen off the coat, deny access to the plant and any vase water, and go directly to a veterinary hospital — bring a sample of the plant. Call ASPCA Animal Poison Control at (888) 426-4435 en route. Survival depends on aggressive IV fluids started early; do not waste time on home decontamination.

The window is narrow: kidney injury develops within 24–72 hours of exposure, and treatment started more than 18 hours after exposure is generally too late to prevent irreversible kidney failure. Any exposure — even suspected pollen contact — should be treated as an immediate emergency.

Oriental Lilies carry an uncertain toxicity classification for dogs. Unlike cats, for whom lilies are life-threatening, dogs appear to experience mainly mild gastrointestinal upset such as vomiting or diarrhea if they ingest any part of the plant.

Expect vomiting or diarrhea, reduced appetite, or temporary lethargy. GI signs typically appear within hours of ingestion and most commonly resolve within 24 hours; larger amounts of petals, leaves, or pollen tend to cause more pronounced symptoms.

Monitor your dog closely for vomiting, diarrhea, or lethargy. Call your vet if GI signs persist beyond 12 hours, if your dog ate a large quantity of the plant, or if you notice refusal to drink or signs of dehydration. For urgent guidance, contact the ASPCA Animal Poison Control Center at (888) 426-4435.

GI signs such as vomiting or diarrhea commonly appear within a few hours of ingestion. The exact timing is not well documented in dogs, but most cases resolve within 24 hours with supportive care; contact your vet if symptoms extend beyond that window.
