D.C.'s second-best panda showed all the signs. There was the hormone in the urine. There was the lack of energy and changes to her appetite. There was the drop in the hormone in the urine, which happens just before birth. And, lastly, there was the fact that she ovulated and the zoo staff attempted to inseminate her with tubed-up semen from Tian Tian, the black-and-white reluctant stud.

But the zoo put out a release today to say it's all a giant panda disappointment. Add it to the list. It's not the first pseudopregnancy for Our Lady of the Fujifilm Giant Panda Habitat. Maybe next year: Yesterday the zoo put Tian Tian to sleep and extracted some more of his boys, destined for the freezer.
