Why do some people strongly discourage composting pet manner while others strongly recommend composting animal manner? Some people say add manure from cows, horses, goats, sheep, pigs, rabbits, chickens, etc. while others say donât add dog, cat, rabbit manure. I understand that animals can carry diseases. But why would dog, cat, or rabbit manure be worse then horse, cow, goat, sheep, chicken, etc.? There is obviously a contradiction unless Iâm missing some information. I always understood that adding any manure would help promote the breakdown of other composting matter. Whatâs your take on the situation?
