Might be you got a bad sample or something!?
I've owned a bottle of this and had several samples and none of them had a "stinky" note or any animalism to them at all. Cuir Mauresque is a warm fruited leather fragrance that doesn't have much, if any of the animalism that I find in other leather fragrances such as Aoud Cuir d' Arabie for example. You should try another sample because it doesn't smell as you describe it, imo. It's a quite nice leather if just a bit old fashioned feeling from the warm fruited opening notes. But I could not find any animal qualities to it in my bottle.
