An orangutan at a zoo in Southwest China is missing his pregnant mate so much that he has started to dig a tunnel in the hope of being reunited with her.
Yunnan Wild Animal Park quarantined La Tewhen when she fell pregnant, much to the dismay of male orangutan Pei Pei.
According to the zoo Pei Pei has become quite depressed since being separated from his "wife."
Pei Pei flatly refused to go back inside his enclosure at the end of the day, staying outside in the exterior pen all night.
The next day zoo keeper Li Kanglan was surprised to discover that Pei Pei had begun to dig a tunnel under the wall leading to the enclosure where La Tewhen is being housed.
"I went out to look for him but he was nowhere to be found," said Li. "He came back when I called his name, though - I guess he was a bit scared of being discovered."
