Veterinarians check the San Diego Zoo's unnamed female giant panda cub's feet during her weekly exam October 19, 2005. They discovered that the cub has grown her first tooth, a left upper molar. For a couple of weeks, veterinarians could feel teeth below the gums but it had not emerged until now. The cub currently weighs 3.5 kg (7.78 pounds). (REUTERS/Ho, Staff photographer)
