Is Spotted Trillium toxic to cats?

Mildly. The ASPCA lists spotted 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. All Trillium species contain steroidal saponins concentrated in the berries and roots. Ingestion by cats or dogs can cause vomiting, diarrhea, and drooling; symptoms are typically self-limiting but veterinary advice should be sought. Trillium is not listed individually on the ASPCA Toxic Plant database, but veterinary sources consistently flag the genus as a GI irritant.

All Trillium species contain steroidal saponins concentrated in the berries and roots. Ingestion by cats or dogs can cause vomiting, diarrhea, and drooling; symptoms are typically self-limiting but veterinary advice should be sought. Trillium is not listed individually on the ASPCA Toxic Plant database, but veterinary sources consistently flag the genus as a GI irritant. 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 spotted 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: Spotted Trillium is mildly toxic to dogs as well. See the full spotted trillium pet-safety guide for both species.
