While plants add a touch of color and fragrance to our daily lives they also inject an element of danger into the lives of our pets. More than 700 plants have been identified as producing physiologically active or toxic substances in sufficient amounts to cause harmful effects in animals. Poisonous plants produce a variety of toxic substances and cause reactions ranging from mild nausea to death. Certain animal species may have a peculiar vulnerability to a potentially poisonous plant.

Below is a list of some of the common plants which may produce a toxic reaction in animals. This list is intended only as a guide to plants which are generally identified as having the capability for producing a toxic reaction.
