If you think mammals in particular when talking about pheromones, then you haven't been exposed to the natural world that much. Class Mammalia has a lot of organsms that can produce pheromones but Class Instecta has tons more, the entire Kindom Animalia if chock-full of them, heck, even Kingdom Plantae uses them too.
