Composting POOP What to Avoid & What is OK
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.
POOP YOU CAN SAFELY ADD TO YOUR COMPOSTER:
Who’s poop is OK to use in a compost pile? Herbivores. Cows, horses, sheep, essentially all grass grazing animals produce great nitrogen-rich droppings that are safe to use in a compost bin. It may not be glamorous, but shoveling in a cow pie or two will give your compost pile a real boost.
Try using pies that are not the freshest in the field, but instead, use droppings that have started to dry out or decompose already. This way, they can be made into smaller pieces and not just one lump piece floating around. This will help make it more effective in your pile or bin.
Other animals with beneficial poop for your composter: bats, ducks, goats, pigs, pigeons and any other vegetarian animal! Be careful with bird droppings because it might contain weed seeds.
