Is Twisted Trillium toxic to cats?

Mildly. The ASPCA lists twisted 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. Contains steroidal saponins present throughout the plant. Ingestion by cats or dogs typically causes GI upset including vomiting and diarrhea. The fetid odor of the flowers may deter curious animals, but the berries can be attractive. Contact a vet if a pet eats any part of this plant. Not listed individually on the ASPCA Toxic Plant database.

Not listed individually on the ASPCA Toxic Plant database. Signs usually appear soon after chewing rather than hours later — watch for drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy after your cat has had access to twisted trillium.

Stay calm. Remove any plant from your cat's mouth and take the plant away. Note how much was eaten and when, and do not induce vomiting unless told to. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice; a leaf or photo helps the vet treat it correctly.

The ASPCA classification Growli uses applies to both cats and dogs: Twisted Trillium is mildly toxic to dogs as well. See the full twisted trillium pet-safety guide for both species.
