My cat ate Great White Trillium — what to do
Step by step
- Take great white trillium 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 a poison-control line — (888) 426-4435 in the US, or Animal PoisonLine on 01202 509 000 in the UK. Both charge a consultation fee. 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 in the US, or Animal PoisonLine on 01202 509 000 in the UK.
My cat ate great white trillium — FAQ
Is great white trillium poisonous to cats?
Yes — Great White Trillium (Trillium grandiflorum) is regarded as mildly toxic to cats, based on genus- and family-level toxicity data. Trillium grandiflorum is not individually listed on the ASPCA Toxic or Non-Toxic Plant database. All parts of the plant — particularly the berries and roots — are understood to contain steroidal saponins that can cause mild gastrointestinal upset (nausea, vomiting, diarrhoea) if ingested by pets or humans. Not considered life-threatening, but ingestion by pets should be monitored and a vet consulted if symptoms develop. Contact ASPCA Animal Poison Control (888-426-4435 in the US, or Animal PoisonLine on 01202 509 000 in the UK) for guidance.
How serious is it if my cat ate great white trillium?
Great White Trillium is mildly toxic, so most cats get short-lived mouth irritation, drooling, and vomiting rather than a life-threatening reaction. It is still worth a vet call to be safe, especially if your cat ate a lot or symptoms persist.
What symptoms should I watch for?
Signs usually appear soon after chewing: drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy. Trillium grandiflorum is not individually listed on the ASPCA Toxic or Non-Toxic Plant database. All parts of the plant — particularly the berries and roots — are understood to contain steroidal saponins that can cause mild gastrointestinal upset (nausea, vomiting, diarrhoea) if ingested by pets or humans. Not considered life-threatening, but ingestion by pets should be monitored and a vet consulted if symptoms develop. Contact ASPCA Animal Poison Control (888-426-4435 in the US, or Animal PoisonLine on 01202 509 000 in the UK) for guidance. Any worsening or persistent symptoms warrant an immediate vet visit.
Should I make my cat vomit?
No — do not induce vomiting unless a vet or a poison-control specialist specifically tells you to. The wrong action can make things worse. Call your vet, or (888) 426-4435 in the US, or Animal PoisonLine on 01202 509 000 in the UK, and follow professional advice.
How do I stop this happening again?
Keep great white trillium well out of reach, or swap it for an ASPCA non-toxic plant — see the best cats-safe plants list.
