Is golden japanese sweet flag safe for cats and dogs?
Not entirely — golden japanese sweet flag is mildly toxic to cats and dogs. It rarely causes serious harm, but chewing it triggers real discomfort, so keep it out of a pet's 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. Acorus gramineus is not individually listed on the ASPCA toxic or non-toxic plant database. Although some growers describe it as low-risk and it lacks the high β-asarone load of A. calamus, it shares the same genus as that toxic species, so it should be treated as uncertain and kept out of reach. Chewing may cause oral irritation or mild GI upset; verify with a vet if a pet ingests it.
