Are poinsettias poisonous to pets?
Irritating but not poisonous describes the general interaction between pets and poinsettias (Euphorbia pulcherrima).
Specifically, bright colors on insects and plants tend to serve as warnings to the rest of wildlife that the taste is undesirable and the consequences upsetting or fatal. In the case of poinsettias, eating the plant most likely will have the same effect that eating blades of grass will have on pets romping about the lawn. They may throw up and have diarrhea. But they will not die.
