The cub was born Sunday but his mother, Toma, has refused to nurse him.
Zoo officials gave the mother a drug to stimulate milk production, thinking that might jump start her maternal instincts.
But that hasn't happened.
Instead, the cub will be bottle fed and the zoo will try to find a companion for the animal until he can be weaned.
The Association of Zoos and Aquariums says helps to put a dog or another abandoned cub with a cub that is being raised by hand.
