Is Star-flowered Solomon's Seal toxic to cats?

Mildly. The ASPCA lists star-flowered solomon's seal 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. Berries contain saponins and may cause mild gastrointestinal irritation if ingested in significant quantities by humans or pets. Maianthemum stellatum is not individually listed by ASPCA as toxic or non-toxic. Based on genus-level chemistry and the absence of a non-toxic listing, treat as mildly toxic and prevent ingestion by children and pets.

Berries contain saponins and may cause mild gastrointestinal irritation if ingested in significant quantities by humans or pets. Maianthemum stellatum is not individually listed by ASPCA as toxic or non-toxic. Based on genus-level chemistry and the absence of a non-toxic listing, treat as mildly toxic and prevent ingestion by children and pets. 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 star-flowered solomon's seal.

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: Star-flowered Solomon's Seal is mildly toxic to dogs as well. See the full star-flowered solomon's seal pet-safety guide for both species.
