Is Southern Shield Fern toxic to cats?

Thelypteris kunthii

Mildly toxic to cats

Mildly. The ASPCA lists southern shield 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. Thelypteris kunthii is not individually listed in the ASPCA Toxic and Non-Toxic Plants database. It is a true fern with no recognised toxic principle; other Thelypteris species are generally considered non-toxic, but because this species lacks an individual ASPCA listing, treat with caution and verify with a vet before assuming it is safe for pets.

  4. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice.
