Mildly. The ASPCA lists goldencup st. john's wort 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. H. patulum contains hypericin and related naphthodianthrones. While not rated as highly toxic, the Hypericum genus is considered mildly toxic to pets (dogs, cats) and livestock, potentially causing photosensitisation and GI upset.
