My cat ate Round-leafed Stephania — what to do
Step by step
- Take round-leafed stephania 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 round-leafed stephania — FAQ
Is round-leafed stephania poisonous to cats?
Yes — the ASPCA lists Round-leafed Stephania (Stephania rotunda) as toxic to cats. Stephania rotunda contains pharmacologically potent isoquinoline alkaloids (including l-tetrahydropalmatine and cepharanthine) used in traditional medicine and pharmaceutical research. These alkaloids are toxic to animals and humans in uncontrolled doses. The genus is not individually listed by ASPCA, but due to confirmed alkaloid toxicity, the plant should be kept away from pets and children.
How serious is it if my cat ate round-leafed stephania?
Round-leafed Stephania is toxic to cats and reactions can be significant, so treat any ingestion as urgent. Call your vet or poison control on (888) 426-4435 straight away rather than waiting to see if symptoms develop.
What symptoms should I watch for?
Signs usually appear soon after chewing: drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy. Stephania rotunda contains pharmacologically potent isoquinoline alkaloids (including l-tetrahydropalmatine and cepharanthine) used in traditional medicine and pharmaceutical research. These alkaloids are toxic to animals and humans in uncontrolled doses. The genus is not individually listed by ASPCA, but due to confirmed alkaloid toxicity, the plant should be kept away from pets and children. 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 round-leafed stephania well out of reach, or swap it for an ASPCA non-toxic plant — see the best cats-safe plants list.
