My cat ate Stinking Trillium — what to do

Step by step

  1. Take stinking trillium away and remove any plant material from your cat's mouth so they cannot eat more.
  2. Note roughly how much was eaten and when — this helps the vet judge the risk.
  3. Do NOT induce vomiting unless a vet or poison-control specialist tells you to.
  4. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 (a consultation fee may apply) and follow their advice.
  5. 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 stinking trillium — FAQ

Is stinking trillium poisonous to cats?

Yes — the ASPCA lists Stinking Trillium (Trillium foetidissimum) as mildly toxic to cats. Trillium foetidissimum is not individually listed by the ASPCA on its Toxic or Non-Toxic Plant database. As with other Trillium species, roots and berries are the parts of greatest concern and likely contain steroidal saponins that can cause gastrointestinal irritation (nausea, vomiting, diarrhoea) in pets and humans if ingested. The strong scent may deter animal ingestion but should not be relied upon as a safety mechanism. Contact ASPCA Animal Poison Control (888-426-4435) or a vet promptly if ingestion occurs.

How serious is it if my cat ate stinking trillium?

Stinking 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 foetidissimum is not individually listed by the ASPCA on its Toxic or Non-Toxic Plant database. As with other Trillium species, roots and berries are the parts of greatest concern and likely contain steroidal saponins that can cause gastrointestinal irritation (nausea, vomiting, diarrhoea) in pets and humans if ingested. The strong scent may deter animal ingestion but should not be relied upon as a safety mechanism. Contact ASPCA Animal Poison Control (888-426-4435) or a vet promptly if ingestion occurs. 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 the ASPCA Animal Poison Control Center specifically tells you to. The wrong action can make things worse. Call (888) 426-4435 and follow professional advice.

How do I stop this happening again?

Keep stinking trillium well out of reach, or swap it for an ASPCA non-toxic plant — see the best cats-safe plants list.
