Is mustard greens 'golden streaks' safe for cats and dogs?
Mildly. The ASPCA flags mustard greens 'golden streaks' as mildly toxic to cats and dogs — a chewing pet gets oral irritation and drooling rather than a medical emergency, but it is still worth a high shelf. 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. Brassica juncea is not individually listed by the ASPCA, but Brassica greens contain glucosinolates and isothiocyanates that can cause gastrointestinal upset, drooling and, in large quantities, anaemia or thyroid effects in cats and dogs. Treat with caution and verify with a vet before allowing access.
