"Take that, Bambi."
Tininess + huge eyes + spindly legs = number of strange, sappy noises made by grown-ups. Take this math, apply to this teeny-tiny mouse deer mama and teenier-tinier mouse deer baby, and the result is a cacophony of clucking and aws. The bonus: 10 percent of all proceeds of ZooBorns (the book in which this photograph appears) go to support the Association of Zoos and Aquariums' Conservation Endowment Fund. So smile, lower your blood pressure and help the world—all at the same time.
