Human women, whose sense of smell is more sensitive than mens, have more olfactory neurons than the general population of mice but fewer than rats, and have much larger olfactory bulbs than both rodents. Armadillos also have an inability to regulate their own body temperature, so cold temperatures can threaten their health and even lead to death.
