There are no toxic ingredients in any of our soils or fertilizers. The ingredients are all natural and organic. Pets do tend to be attracted to some of the ingredients. Since it is not food, it is best to keep them away. If they do end up eating some, they may have an upset stomach. It is best to work fertilizers into the soil and thoroughly water after application. If you have any further concerns about the health of your pet please consult a veterinarian.
