JERUSALEM (AP) -- A man clad only in underwear and a T-shirt wrestled a wild leopard to the floor and pinned it for 20 minutes after the cat leapt through a window of his home and hopped into bed with his sleeping family. "This kind of thing doesn't happen every day," said 49-year-old Arthur Du Mosch, a nature guide. "I don't know why I did it. I wasn't thinking, I just acted." Raviv Shapira, who heads the southern district of the Israel Nature and Parks Protection Authority, said a half dozen leopards have been spotted recently near Du Mosch's small community of Kibbutz Sde Boker in the Negev desert in southern Israel, although they rarely threaten humans.
