A rare Amur tiger cub born last month at the Great Plains Zoo is in good health and maintains a strong appetite.

Two of the cubs born in a litter of six died last week.  But the sole survivor has now doubled in size and her eyes are starting to open. 

Zookeepers will continue to hand-feed the cub, and make sure she gets plenty of rest.

We'll check the cub's progress tonight on KELOLAND News.
