WASHINGTON, June 20 (UPI) -- Officials at Washington's National Zoo say there are signs that one of its beloved pandas might be pregnant.
Urine tests on Mei Xiang have revealed a hormone spike that could mean she is expecting, The Washington Post said Friday.
But zookeepers aren't passing out cigars just yet. Pandas are notorious for "pseudopregnancies," and Mei Xiang has had four of them since 2005.
It will likely be mid-July before a genuine pregnancy can be cofirmed, zoo officials said.
