Is Poinsettia toxic to cats?

Poinsettia is only mildly toxic to cats (S1 Caution): its milky sap can cause drooling, vomiting, and skin irritation, but its reputation as a deadly plant is greatly exaggerated — signs are usually self-limiting.

FAQ

Are poinsettias really deadly to cats?

No — that reputation is a myth the sources themselves push back on. The ASPCA describes poinsettia as "generally over-rated in toxicity," and Pet Poison Helpline says the "poisoning is greatly exaggerated." What actually happens: the milky sap can cause drooling, mild vomiting, or skin irritation, and signs usually resolve on their own. It's an S1 on our scale — caution, not crisis.

Do I need to get rid of my poinsettia at Christmas because of my cat?

Not necessarily — keeping it out of nibbling range is usually enough. Per Pet Poison Helpline, "signs are generally self-limiting and typically don't require medical treatment." Call your vet only if signs are severe or persistent — ongoing vomiting, refusal to eat, or worsening skin or eye irritation.
