Is coris-leaved st john's wort safe for cats and dogs?
Toxic — the ASPCA lists coris-leaved st john's wort as a clear no for cats and dogs. The painful part for the pet is usually quick and intense; the right move is to keep it out of any room a pet roams unsupervised. This classification follows the ASPCA Toxic and Non-Toxic Plant List, the most widely used reference for companion-animal plant safety in the US and the standard most UK vets cite as well. ASPCA lists Hypericum (St John's wort) as toxic to dogs, cats, and horses; the toxic principle is hypericin, which causes photosensitisation — ulcerative and exudative dermatitis when exposed to sunlight after ingestion. Seek veterinary advice immediately if ingestion is suspected.
