Life has developed in some offbeat ways, as it tends to do. Of course we being us think of ourselves as the norm. To the extent that bats--seen below--have been objects of fear and revulsion, I think that's largely why. The hanging like dead banana leaves, the membranous wings, the solid walls of bats in some underground nooks. It just doesn't square with what mammals are supposed to be.
Being able to observe the young 'uns close up may change that. Baby bats are quite kittenish, and very warm. It's hard to keep that aloof attitude toward creatures of the night when you see them drinking out of a mini baby bottle.
