Is southern red trillium safe for cats and dogs?
Mildly. The ASPCA flags southern red trillium as mildly toxic to cats and dogs — a chewing pet gets oral irritation and drooling rather than a medical emergency, but it is still worth a high shelf. 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. As with all Trillium species, T. sulcatum contains steroidal saponins which act as GI irritants. Ingestion by cats or dogs typically causes vomiting, diarrhea, and excess salivation. Consult a veterinarian if a pet consumes any part of the plant. Not individually listed on the ASPCA Toxic Plant database.
