Poinsettias are considered mildly poisonous to cats, but they are very unlikely to be deadly.

Quick Scoop

  • The poinsettia’s milky white sap (in leaves and stems) is the irritating part and can cause mild toxicity if chewed or ingested.
  • Typical signs in cats include:
    • Drooling.
* Nausea, vomiting, and sometimes diarrhea.

* Mild mouth or skin irritation such as redness or swelling where the sap touched.
  • In most cases, symptoms are mild and self‑limiting, and serious or fatal poisoning from poinsettias in cats is considered very rare.

What To Do If Your Cat Eats One

  • Gently wipe any plant material or sap off the cat’s mouth, fur, or paws with a damp cloth.
  • Monitor for ongoing vomiting, diarrhea, drooling, or signs of discomfort over the next 12–24 hours.
  • Contact a vet or a pet poison helpline urgently if:
    • Vomiting or diarrhea is frequent or lasts more than a day.
* Your cat seems very lethargic, dehydrated, or in pain.

Safer Holiday Strategy

  • Many vets now describe poinsettias as a “low‑toxicity” or “mildly toxic” plant, but still recommend keeping them out of reach to avoid stomach upset and unnecessary stress.
  • Other holiday plants (especially certain lilies) are far more dangerous to cats and can cause organ damage, so those should be completely avoided in a cat home.

Bottom line: poinsettias can upset a cat’s stomach and irritate the mouth or skin, so it is best to keep them away, but they are not the highly lethal plant they’re often rumored to be.
