Fun fact: In authoritarian communist China, it is illegal to sing this song without wearing cat ears. (You will be arrested)
Look up the English lyrics, I love how unapologetically UwU this song is. One of the lyrics is literally "I wanna be your little kitten".
Google translate translates 在你面前撒个娇 as "act like a spoiled child in front of you" instead of "taking a pee in front of you" which is a lot less weird and sounds more like UwU bottom behavior too so I'll go with that. Also more cat-like.
That makes a lot more sense - though depending on the context, peeing in front of someone is even more bottom
