Is austral bracken safe for cats and dogs?
Toxic — the ASPCA lists austral bracken as a clear no for cats and dogs. The painful part for the pet is usually quick and intense; the right move is to keep it out of any room a pet roams unsupervised. 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. Pteridium esculentum contains ptaquiloside, a carcinogenic and immunosuppressive compound toxic to livestock, cattle, and horses with chronic exposure. It also contains thiaminase. The ASPCA lists bracken ferns (Pteridium aquilinum, closely related) as toxic to cats, dogs, and horses. Keep pets away from this plant.
