A group of panda cubs are melting hearts this week as they play around and pose in a series of almost unbearably cute photos, from flashing a wave to kicking back and chilling out.
The cubs were snapped in action at the Conservation and Research Center for the Giant Panda at the Wolong Nature Reserve in Sichuan, China, according to photographer Dr. Katherine Feng.
One blissed-out panda cub was the picture of relaxation as he sprawled on his back in an incubator with his paws cupped behind his head.
Medics weighed, measured and fed the 37-day-old before returning him to the see-through box, according to Feng, where he wriggled around and settled on his back.
The 65-year-old photographer also captured one panda lying on its stomach, its paw raised as if to offer a "high five."
In another image, a panda is seen carrying its baby in its mouth just a few hours after the cub was born.
"It was so tempting to pet and play with the baby pandas," Feng said, according to the Sun. "They are roly-poly balls of black and white and so cute to watch."
The photos were taken at the China Conservation and Research Center for the Giant Panda at the Wolong Nature Reserve in Sichuan, China.
Feng, a former veterinarian, became passionate about pandas when she first visited the Wolong Nature Reserve on a trip to China in 1982.
Her photos were featured in the book "Panda Kindergarten," and the Colorado-based photographer now returns to the wildlife preserve several times a year.
