My cat ate Bok Choy 'Black Summer' — what to do
Step by step
- Take bok choy 'black summer' 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 a poison-control line — (888) 426-4435 in the US, or Animal PoisonLine on 01202 509 000 in the UK. Both charge a consultation fee. 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 in the US, or Animal PoisonLine on 01202 509 000 in the UK.
My cat ate bok choy 'black summer' — FAQ
Is bok choy 'black summer' poisonous to cats?
Yes — Bok Choy 'Black Summer' (Brassica rapa var. chinensis 'Black Summer') is regarded as mildly toxic to cats, based on genus- and family-level toxicity data. Brassica rapa vegetables 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 small amounts of goitrogens, and large quantities can cause gas, GI upset, or thyroid effects in pets, so feed only sparingly.
How serious is it if my cat ate bok choy 'black summer'?
Bok Choy 'Black Summer' 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 vegetables 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 small amounts of goitrogens, and large quantities can cause gas, GI upset, or thyroid effects in pets, so feed only sparingly. 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 a poison-control specialist specifically tells you to. The wrong action can make things worse. Call your vet, or (888) 426-4435 in the US, or Animal PoisonLine on 01202 509 000 in the UK, and follow professional advice.
How do I stop this happening again?
