Top 10 Animal Moms

Male polar bears are the kings of one-night stands. These Casanovas give females the cold shoulder after mating, leaving the moms-to-be to put on around 400 pounds during their pregnancy! That's a lot of "baby weight," but in this case, late-night cravings are encouraged — in fact, if the female doesn't find enough food to double her weight, her body will actually reabsorb the fetus. Sound like something from a science fiction movie? It's all too true. After she packs on the pounds, the polar bear has one of the easiest labors on record. She digs a maternity den (usually in a snowdrift), where she goes into a hibernation-like state, doesn't eat for two months and also sleeps through the baby's birth. Can you imagine? "Push!" "Zzzzzz." "One more!" "Zzzzzz." Newborns are blind and toothless, but super cute, and they generally stay by their mom's side for just two years before being sent out on their own — sort of like condensing the toddler, tween and adolescence years. A todtweenscence, perhaps? Hmm.
