On Friday, officials from the Memphis Zoo announced they were conducting a 24-hour watch to determine whether or not the giant panda Ya Ya is pregnant. The watch began on Thursday, and as of Saturday, there is still no word.
According to a release sent out by the zoo, Ya Ya was artificially inseminated in January, 112 days ago. Gestation periods for pandas average 133 days. Because of the cub’s small size — around the size of a “stick of butter” at birth — pregnancies are hard to determine.
Ya Ya has been showing signs that she may be pregnant, according to the release. Those signs include lack of appetite and irritability.
