Hong Kong's panda enthusiasts were treated to a heartwarming sight on Monday as Ocean Park Hong Kong uploaded a new video of a panda cub being bottle-fed.

The clip, posted on Ocean Park's Instagram account, features "Little Brother" — the younger of the twin cubs born in August — wriggling and vocalizing on the caregiver's lap before settling down to drink milk contentedly.

"'Do Not Disturb Mode' on! I need to concentrate on drinking my milk," read the caption accompanying the video.

Panda fans flooded the comments section, expressing their delight at the update on the cute pair, who are expected to make their public debut around the Lunar New Year in late January.

"This is my spiritual food on Monday," declared one Instagram user, while another commented on the cub's vocalizations, saying "So cute! It keeps vocalizing until it's satisfied!"
