One of the panda cubs recently born at the National Zoo in Washington, DC has died, the zoo confirmed.
Few days ago I posted a news about the joyful birth of the twin cub, but now one is gone.
The smaller panda cub was incubated by zookeepers because its mother Mei Xiang had trouble nursing both cubs.
Staff swapped the small cub in for feeding with her mother Tuesday night and saw the cub was struggling this morning.
"When we realised the cub wasn't going to make it, it was devastating," zoo staff said.
The zoo said it was "prepared" to rear twin cubs and did everything it could to keep both of them alive.
Antibiotics and other liquids could not save the cub, who was having respiratory issues.
No official cause of death has been named, but the zoo is running tests to figure it out.
