Pandas

Experts in China are working with Michigan State University to grow the population size of wild, protected pandas.

Don't let his pudgy appearance fool you. Xiao Liwu is getting more muscular from climbing around his new exhibit.

Earlier this month, the San Diego Zoo's adorable giant panda cub Xiao Liwu went on exhibit.

And when it comes to training a cub, mommy knows best.

The cuddly creatures have a potent antibiotic in their immune systems.

This little panda cub rang in the New Year with a clean bill of health.

Xiao Liwu was distracted during his exam by a doughnut-shaped plastic ring, a stick of bamboo and a plastic ball.

Much like a toddler, the fidgety bear cub at the San Diego Zoo calms down when he has a toy to play with.

At 4 1/2 months old, Xiao Liwu is growing into a rambunctious cub.
