This handout photo provided by the Smithsonian's National Zoo, taken Jan. 6, 2014, shows keepers bottle-feeding the saved sloth bear cub at the zoo in Washington. Animal keepers at the National Zoo have saved a sloth bear cub after two others were eaten by the mother. The three cubs were born in December to a mother named Khali. One was eaten within 20 minutes, and a second cub was eaten after seven days. The zoo says it's not uncommon for carnivores to eat their young if they're compromised somehow.
