Is sweet trillium safe for cats and dogs?
Mildly. The ASPCA flags sweet 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. Like other Trillium species, T. vaseyi contains steroidal saponins concentrated in the roots and berries. Ingestion causes gastrointestinal irritation, vomiting, and diarrhoea in pets and humans. Not individually listed by ASPCA, but the genus is characterised as mildly toxic by NC State Extension. Seek veterinary advice if significant ingestion occurs.
