Is poinsettia toxic to cats?
ASPCA lists poinsettia as toxic to cats; the sap irritates the mouth and stomach. Sources disagree: Cornell says swallowing a sizable amount could prove fatal, while the Pet Poison Helpline calls it only mildly toxic.
Good to know: We decide cautiously: keep the plant where your cat can’t reach it.
