Is Canada Mayflower toxic to cats?

Mildly. The ASPCA lists canada mayflower 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. The red berries contain saponins and may cause mild gastrointestinal upset if ingested in quantity by humans or pets. Maianthemum canadense is not individually listed by ASPCA as toxic or non-toxic. Given the genus's saponin content and the lack of an explicit non-toxic listing, treat as mildly toxic and prevent ingestion by children and pets.
