A cow grazes on a grassy knoll in La Lecherette, Switzerland. Launched five years ago, a cow adoption project called Mavachamoi -- word play in French for "my cow" -- is proving popular among urban dwellers in Switzerland. For 280 euros (350 US dollars), people can reserve a cow for the summer, during which they can visit the animal as often as they wish.
