This classification follows the ASPCA Toxic and Non-Toxic Plant List. ASPCA lists garden mints as toxic to cats and dogs due to essential oils. A nibble is harmless; large amounts cause vomiting and diarrhoea. Pennyroyal (Mentha pulegium) is significantly more toxic and should be avoided in pet homes.
