Playful panda cub Xiao Liwu has been diagnosed with "acute cuteness" by staff at the San Diego Zoo.
"It took three sets of hands to measure and examine panda cub Xiao Liwu. Animal care staff report that the 6-month-old cub is very strong, continues to be playful and isn't very interested in sitting still," the zoo reports.
The vets also confirm that the cuddly-looking cub is getting buff, slimming down and gaining muscle in his legs.
Watch the panda exhibit those symptoms of cuteness below:
"Sometimes he can be so stubborn with his one-track mind, but it always makes for good stories and a great experience for our guests. As the morning came to an end, Xiao Liwu enjoyed playing in the bushes exploring the flowers and leaves. This “little gift” is quite a little adventurer!" writes Alyssa Medeiros, a panda narrator at the San Diego Zoo, of Xiao Liwu's life at the zoo.
"Xiao Liwu, whose name means "Little Gift," was the sixth cub born to the zoo's panda mom Bai Yun. All the San Diego Zoo giant pandas are on a research loan from China, the only place where the species still exists in the wild. Four of Xiao Liwu's siblings have already been moved out of California to join the Chinese panda conservation and breeding program," LiveScience reports.
When Xiao Liwu was born, the San Diego Zoo set a record for having the most cubs born to a panda facility outside of China, TODAY reports.
Fans of the panda cub can watch him on the zoo's live-streaming panda cam.
