The brothers are at the Macao Giant Panda Pavilion, and are currently in good health, said the panda care team
The twin male pandas birthed by panda named Xinxin one month ago in Macao started receiving their first batch of visitors on Tuesday.
The brothers can be found in the Macao Giant Panda Pavilion, and are currently in good health, said the care team.
Unlike their all-pink skin at birth, the cubs now have their parents' black-and-white appearance. Their ears, eyes, arms, legs and shoulders have turned black, and their hairs should have become thicker. Only their noses and faces remain pink.
According to the care team, the twin brothers can live outside the incubators now. The elder one has grown from 135 grams at birth to over 1,000 grams, while the younger one now weighs more than 700 grams compared with 53.8 grams a month before.
According to a care team member from China's Chengdu Research Base of Giant Panda Breeding in southwest China's Sichuan Province, the brothers are developing healthily. But given that the younger one weighed less than 54 grams at birth and it's difficult for panda cubs with such light birth weight to survive, the whole team will continue their 24-hour observation and care.
The team member added that the cubs will eventually open their eyes, grow out primary teeth, and start to listen and crawl. They will probably live with their mother Xinxin for the next one or two years, and then start to live independently.
"We have been observing their (Kaikai and Xinxin, the cubs' parents) behaviors. We wanted to know if they liked each other. Kaikai is a quick-tempered young male, but he became a little bit shy when meeting a female, while Xinxin is a well-mannered lady, yet she was quite proactive during mating season," said Zhao Chuangkun, a keeper.
The cubs' parents Xinxin and Kaikai were chosen from the Chengdu Research Base of Giant Panda Breeding as a gift from the central government to China's Macao Special Administrative Region.
