Is White Trillium toxic to cats?

Trillium grandiflorum

Mildly toxic to cats

Mildly. The ASPCA lists white trillium as mildly toxic to cats — a chewing cat typically gets mouth irritation, drooling, and vomiting rather than a medical emergency, but it is still best kept out of reach. This classification follows the ASPCA Toxic and Non-Toxic Plant List. Trillium grandiflorum is not listed on the ASPCA toxic or non-toxic plant database. All parts of the plant — particularly the berries and roots — 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 occur.

What to do if your cat ate white trillium

  1. Remove any plant material from your cat's mouth and move white trillium out of reach.
  2. Note how much was eaten and when, and watch for drooling, vomiting, or lethargy.
  3. Do not induce vomiting unless a vet or poison-control specialist instructs you to.
  4. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice.
  5. Bring a leaf or photo of white trillium to the appointment so it can be treated correctly.

General guidance, not veterinary advice. If you think your cat has eaten white trillium, contact your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 — do not wait for symptoms to worsen.
