My cat ate Black Cohosh — what to do

Step by step

  1. Take black cohosh away and remove any plant material from your cat's mouth so they cannot eat more.
  2. Note roughly how much was eaten and when — this helps the vet judge the risk.
  3. Do NOT induce vomiting unless a vet or poison-control specialist tells you to.
  4. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 (a consultation fee may apply) and follow their advice.
  5. 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 black cohosh — FAQ

Is black cohosh poisonous to cats?

Yes — the ASPCA lists Black Cohosh (Actaea racemosa) as mildly toxic to cats. All parts of Actaea racemosa contain triterpene glycosides and may cause gastrointestinal upset (vomiting, diarrhoea) if ingested by pets or humans. The ASPCA does not individually list this species, but the Ranunculaceae family is broadly considered irritating. Keep away from pets and children; the rhizome is used medicinally but is toxic in large doses.

How serious is it if my cat ate black cohosh?

Black Cohosh 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. All parts of Actaea racemosa contain triterpene glycosides and may cause gastrointestinal upset (vomiting, diarrhoea) if ingested by pets or humans. The ASPCA does not individually list this species, but the Ranunculaceae family is broadly considered irritating. Keep away from pets and children; the rhizome is used medicinally but is toxic in large doses. 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 black cohosh well out of reach, or swap it for an ASPCA non-toxic plant — see the best cats-safe plants list.
