How do numbats breathe?

Male numbats attract females by using their scent gland. Prior to the mating season, which occurs through December and January, the male's stern all gland, positioned in the middle of the top of its chest, starts to exude a strong-smelling, oily substance. This not only turns its fur red, but the numbat uses it to rub over rocks and logs to let females know he is ready to mate.
