The mummy bear was spotted showering her cub with affection, cuddles and tickles at Taipei Zoo in Taiwan, China earlier this month and we can imagine that the pair attracted a lot of attention from admiring visitors.
We can't stop cooing over these cute snaps!
One picture sees Yuan Yuan turning little Yuan Zai upside down, while she appears to tickle his toes, while another photo shows the pair snuggled up together, as Yuan Yuan gives her baby a big bear hug.
If this isn't enough fluffiness to warm your hearts, check out more cute animals in our gallery below.
