Is Yokosuka Lady Fern toxic to cats?

Athyrium yokoscense

Mildly toxic to cats

Mildly. The ASPCA lists yokosuka lady 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. Athyrium yokoscense is not individually listed by the ASPCA. General cautions for the Athyrium genus note that many ferns contain thiaminase and some may contain unspecified carcinogens (per PFAF); until individually evaluated by ASPCA, a mildly-toxic classification is the appropriate precaution.
