POOP TO AVOID COMPOSTING:
Because domestic house pets (like dogs and cats) are carnivorous by nature, their poop should NOT be added to a compost pile. Human poop also (even if someone is a vegetarian!) should never be added to a compost bin or pile. Both dogs and cats have organisms in their stomachs and can also have diseases in their poop that are harmful to the composting process and plant life, and ultimately humans. These diseases can get into the plants you eat, and should not be digested. Human poop can carry pathogens, diseases and organisms that can be extremely harmful.
