Is grapefruit mint safe for cats and dogs?
Toxic — the ASPCA lists grapefruit mint 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 Mint (Mentha sp.) as toxic to cats, dogs and horses; the toxic principle is essential oils, causing vomiting and diarrhoea with large ingestions. Casual nibbling is usually mild, but prevent pets eating quantities and never offer mint essential oil.
