Tian Tian had been keeping keepers at Edinburgh Zoo guessing over her possible pregnancy since she was artificially inseminated in April.
In August, experts noted signs that she was pregnant and it was hoped a panda cub would be born by September and the panda enclosure was closed three weeks ago.
Chris West, Chief Executive Officer for the Royal Zoological Society of Scotland said:
“The panda enclosure will remain closed until the end of the week, in order to give Tian Tian time to get back into her routine and provide her keepers with the chance to recuperate after this long period of waiting.”
