SAN DIEGO (CNS) - The giant panda cub at the San Diego Zoo is up to almost five pounds and his eyes are nearly open, animal care staff reported Thursday following a weekly veterinary examination.
The unnamed cub born July 29 weighs 4.9 pounds -- a gain of nearly one pound since last week -- and his vision is probably limited to light and shadow, according to his handlers, who say scratching behind his ears triggers a kicking reflex similar to that of a dog.
His mother, Bai Yun, has started taking the cub out of their den so she can snack on bamboo.
The public has until Monday to suggest names for the cub online at www.sandiegozooglobal.org/panda-name. Suggestions must be in Chinese pinyin, the method for transcribe Chinese characters into Latin script, and the significance of the name must be included, zoo officials said.
The cub's name will be announced in November, when he becomes 100 days old, which is Chinese tradition.
