Nikki, a 370-pound male tiger, has refused to come out of his den into the public exhibit since it opened two months ago. Anna, a 300-pound female tiger, regularly prowls the new space.
Zoo officials won't put the two tigers together because they've yet to meet. For now, officials are hoping the scent of the female tiger will draw Nikki into the new exhibit. Once he becomes used to it, zoo officials will put both tigers on display at the same time; but for now, they're trying to coax Nikki into the space alone.
Zoo officials are hoping Nikki and Anna will breed at the zoo.
