My cat ate Blue Chalksticks — what to do

Step by step

  1. Take blue chalksticks 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 blue chalksticks — FAQ

Is blue chalksticks poisonous to cats?

Yes — the ASPCA lists Blue Chalksticks (Curio repens (syn. Senecio serpens)) as mildly toxic to cats. Blue chalksticks (Curio repens / Senecio serpens) is not individually listed in the ASPCA toxic-plant database, but the ASPCA names its close relative, string of pearls (Senecio rowleyanus), as causing stomach upset (mainly vomiting) and lethargy, and lists the wider Senecio group as toxic due to pyrrolizidine alkaloids. Because the genus is not clean, treat blue chalksticks as mildly toxic to cats and dogs, keep it out of reach, and verify with your vet if a pet ingests any; the sap can also irritate skin, so wear gloves when taking cuttings.

How serious is it if my cat ate blue chalksticks?

Blue Chalksticks 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.
