Is Red Trillium toxic to cats?

Trillium erectum

Mildly toxic to cats

Mildly. The ASPCA lists red 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 erectum is not individually listed on the ASPCA toxic or non-toxic plant database. Like other Trillium species, it contains steroidal saponins, particularly in the berries and roots, which can cause gastrointestinal irritation (vomiting, diarrhoea) if ingested by pets or humans. Historically the rhizome was used medicinally, but should not be considered safe for unsupervised pet access.

What to do if your cat ate red trillium

  1. Remove any plant material from your cat's mouth and move red 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 red trillium to the appointment so it can be treated correctly.

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