Is painted trillium safe for cats and dogs?
Use caution. Painted 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 undulatum is not individually listed by the ASPCA. As with other Trillium species, roots and berries may contain irritating compounds (possibly steroidal saponins). Exercise caution and keep pets and children from ingesting any part. Consult ASPCA Animal Poison Control (888-426-4435) if ingestion occurs.
