Kitten Girls

Kitten Girls (키튼걸스) were a three-member girl group under Stone Entertainment. They officially debuted on September 4, 2018, with the single "U Me Us". They presumably disbanded in 2019, after Hongrang had her solo debut and the group's social media accounts stayed inactive. They got their name from their concept "naughty baby cat", which has to do with all their members being under 160cm.
