Answer 1

Why faeces is all different shapes and sizes for mammals, including humans. Go out a little ways and gather up some horsepoo, cowpoo, sheeppoo, birdpoo and maybe even dog poo, but I'd leave the human poo out of the equasion. Too many questions with that, unless of course there is a baby in the house? Obliously the answer is the size of the animal, what it eats and its digestive system eg cows have four stomachs! just a suggestion x

Answer 2
