Is pot marjoram safe for cats and dogs?
No — pot marjoram is toxic to cats and dogs. Keep it well away from any pet that chews plants; reactions can be significant. 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. The ASPCA lists Marjoram (Origanum) as toxic to dogs and cats, and the genus's 'Pot Marjoram' name is cited on its listing. The toxic principle is gastrointestinal irritants causing vomiting and diarrhea; concentrated oregano/marjoram oils are stronger irritants. Keep pets from grazing large amounts and consult a vet on significant ingestion.
