My cat ate Crimson Flag Lily — what to do
Step by step
- Take crimson flag lily away and remove any plant material from your cat's mouth so they cannot eat more.
- Note roughly how much was eaten and when — this helps the vet judge the risk.
- Do NOT induce vomiting unless a vet or poison-control specialist tells you to.
- Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 (a consultation fee may apply) and follow their advice.
- Watch for drooling, pawing at the mouth, vomiting, loss of appetite, or lethargy, and bring a leaf or photo to the appointment.
This is general guidance, not veterinary advice. Pets vary, and a reaction may be to soil, fertiliser, or pesticide as well as the plant. When in doubt, call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435.
My cat ate crimson flag lily — FAQ
Is crimson flag lily poisonous to cats?
Yes — the ASPCA lists Crimson Flag Lily (Hesperantha coccinea) as toxic to cats. Pet Poison Helpline lists Kaffir lily (Hesperantha coccinea) as toxic to dogs and cats. The toxic principle is lycorine, an alkaloid found in all parts of the plant. Clinical signs include vomiting, drooling, retching, and gastrointestinal distress; large ingestions (particularly of the rhizomes) may cause low blood pressure, heart rhythm disturbances, weakness, and seizures. Unlike true lilies (Lilium), it does not cause acute kidney injury in cats.
How serious is it if my cat ate crimson flag lily?
