Stay-at-home dads

In the animal kingdom, as we know it, only 5-10% of species have stay-at-home dads. The scientists say the arrangement only works in a monogamy society. A recent study published in the journal Animal Behaviour has identified bat-eared fox as yet another such species - the women go off to work while the men stay home with the kids. Since these foxes eat insects, only females can process the insects into a food suitable for their young: milk. The male spend all of their time with their babies, they know having young with several mothers and trying to split time between defending all of the litters may end up with fewer offspring than investing everything in a single litter.
