Is Limestone Oak Fern toxic to cats?

Gymnocarpium robertianum

Mildly toxic to cats

Mildly. The ASPCA lists limestone oak fern 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. This classification follows the ASPCA Toxic and Non-Toxic Plant List. Gymnocarpium robertianum is not individually listed in the ASPCA Toxic and Non-Toxic Plants database. It is a true fern with no recognised toxic principle, and ferns of this kind are generally regarded as ASPCA non-toxic; because this species is not individually ASPCA-listed, treat it with caution and verify with a vet before assuming it is pet-safe.
