Taipei, Taiwan (CBS NEWS) -- The giant panda cub Yuan Zai, daughter of Chinese mainland-donated pandas Tuan Tuan and Yuan Yuan, opened her eyes on Aug. 17 in Taipei.
Yuan Zai was found opening her right eye slightly while sucking milk on Aug. 16 afternoon, and her left eye opened on Aug. 17.
According to the Taipei Zoo, it usually takes 45 days for a panda cub to open its eyes, while Yuan Zai opened her eyes when she was 41 days old, several days earlier than expected. However, it took about another two days for her to fully open her eyes.
Meanwhile, in the beginning days, her vision will be blurry.
"Yuan Zai's eyes were half open, and it will take time for her vision to become clear. However, the animals can get familiar with the environment and her mother through smell, sight and hearing," said Chang Chih-hua, s spokesman for the Taipei Zoo.
