FAQ

Does this Dieffenbachia verdict cover a species or the genus?

The genus. The ASPCA's Dieffenbachia entry and Pet Poison Helpline's Dieffenbachia and Gold Dieffenbachia entries all give genus-level scientific names, so this verdict covers Dieffenbachia as a genus. Some other entries name a single species (Dieffenbachia amoena, Dieffenbachia picta, or Dieffenbachia seguine); each of them also describes oral irritation, and none of them changes the verdict. Check the scientific name on the tag before applying this verdict.
