Is Mizuna 'Red Kingdom' toxic to cats?

Brassica rapa var. nipposinica 'Red Kingdom'

Mildly toxic to cats

Mildly. The ASPCA lists mizuna 'red kingdom' as mildly toxic to cats — a chewing cat typically gets mouth irritation, drooling, and vomiting rather than a medical emergency, but it is still best kept out of reach. This classification follows the ASPCA Toxic and Non-Toxic Plant List. Brassica rapa mustard greens are not individually listed on the ASPCA toxic plant database, so a pet-safe label cannot be asserted; treat with caution and verify with a vet. Brassicas contain isothiocyanates and goitrogens, and large quantities can cause gas, GI upset, or thyroid effects in pets, so feed only in small amounts.
