Buttermilk Sky is a Nigerian Dwarf goat and the subject of a video that went viral after it was posted to YouTube on 27 July 2012. The video was taken at Took A Leap Farm, a hobby farm in Houlton, Maine.^[1]

The video was posted on 27 July with the caption "Buttermilk 'plays' with her 'friends'". Buttermilk Sky is seen running animatedly about in a grassy clearing while three other goats of similar size and age look on. On several occasions she jumps up, even hopping over other goats and accosting a human observer. At one point she leaps up and knocks another goat down, an act which has sparked criticism from some Internet commentators for its apparently wilful nature.^[2] The video has received over seven million views on YouTube, has been commented on by Maine Congresswoman Chellie Pingree, and has been featured on The Today Show.^[3]

Buttermilk Sky is part of Took a Leap's dairy goat herd.^[4] She was born at Took a Leap Farm on 17 June 2012^[5] (one of the last kids born that year at the farm^[6]) and was five weeks old when the video was taken in July 2012. Her colour is described as "chamoisee with white belt".^[5] According to her owners, Buttermilk Sky is known for her energy; however, the kicking was a first-time occurrence, which was caught on video by chance.^[3]

One of Buttermilk's owners commented that, before the video went viral, she had pledged to donate $25 to Farm Sanctuary, a not-for-profit animal welfare group, should it receive more than one thousand views. Afterwards, she suggested that a collaborative publicity campaign with Farm Sanctuary was being considered, to take advantage of the attention Buttermilk has received.^[3]
