Body weight is equally distributed on fore and hind legs in quadrupeds.

well, they are smaller animals! if a cat had a pelvis the size of a human's, that would be one huge cat! and come to think of it, i bet a lion or tiger has a larger pelvis than a human.

So? Could it be because humans are "vertical" and there's more weight to support?
