Is red trillium safe for cats and dogs?
Use caution. Red Trillium is on the mildly-toxic side of the ASPCA list. Most ingestions are short-lived but unpleasant for the pet; the cost-free fix is a placement they can't reach. This classification follows the ASPCA Toxic and Non-Toxic Plant List, the most widely used reference for companion-animal plant safety in the US and the standard most UK vets cite as well. 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.
| Pet | Toxic? | Per ASPCA |
