Safety status
What this means for your cat
Cats are not the species at risk from Yellowrocket. ASPCA lists Barbarea vulgaris as non-toxic to cats — the isothiocyanate toxicity it carries is a horse-and-livestock concern, not a feline one. A curious cat that mouths the bitter mustardy foliage is much more likely to spit it out than to swallow enough to matter.
