My cat ate Mizuna 'Red Kingdom' — what to do
Step by step
- Take mizuna 'red kingdom' away and remove any plant material from your cat's mouth so they cannot eat more.
- Note roughly how much was eaten and when — this helps the vet judge the risk.
- Do NOT induce vomiting unless a vet or poison-control specialist tells you to.
- Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 (a consultation fee may apply) and follow their advice.
- Watch for drooling, pawing at the mouth, vomiting, loss of appetite, or lethargy, and bring a leaf or photo to the appointment.
This is general guidance, not veterinary advice. Pets vary, and a reaction may be to soil, fertiliser, or pesticide as well as the plant. When in doubt, call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435.
My cat ate mizuna 'red kingdom' — FAQ
Is mizuna 'red kingdom' poisonous to cats?
Yes — the ASPCA lists Mizuna 'Red Kingdom' (Brassica rapa var. nipposinica 'Red Kingdom') as mildly toxic to cats. 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.
How serious is it if my cat ate mizuna 'red kingdom'?
Mizuna 'Red Kingdom' is mildly toxic, so most cats get short-lived mouth irritation, drooling, and vomiting rather than a life-threatening reaction. It is still worth a vet call to be safe, especially if your cat ate a lot or symptoms persist.
What symptoms should I watch for?
Signs usually appear soon after chewing: drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy. 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. Any worsening or persistent symptoms warrant an immediate vet visit.
Should I make my cat vomit?
No — do not induce vomiting unless a vet or the ASPCA Animal Poison Control Center specifically tells you to. The wrong action can make things worse. Call (888) 426-4435 and follow professional advice.
How do I stop this happening again?
Keep mizuna 'red kingdom' well out of reach, or swap it for an ASPCA non-toxic plant — see the best cats-safe plants list.
