Only mildly. Poinsettia is listed as toxic to dogs and cats, but its reputation is far worse than the reality: a pet that chews it usually gets nothing worse than a sore mouth and an upset stomach.
Poinsettia (Euphorbia pulcherrima) has a milky sap that irritates the mouth and stomach. The ASPCA describes its toxicity as generally overrated, and the Pet Poison Helpline says most cases can be managed at home. The idea that a few leaves can seriously poison a pet is a myth. At Christmas the bigger dangers are usually nearby: chocolate, and the true lilies in festive bouquets, which can kill cats.
Drooling, lip licking, pawing at the mouth, and sometimes vomiting or diarrhoea. The sap can also mildly irritate the skin or eyes. Signs are usually mild and pass within a day.
Wipe out your pet's mouth with a damp cloth and offer fresh water. Most pets need no treatment. Call your vet if vomiting or diarrhoea is severe or lasts more than a day, because the main risk is dehydration. If sap gets in your pet's eyes, rinse them gently with water.
