She also has a smiley on her belt buckle...

The cat pin looks like someone drew it in their notebook in a couple of seconds. All of the symbols so far were precise.

Another reason (and the biggest) why I don't think it's her symbol is that it is multicolored. Symbols are shapes so they can be used with different colors (Blake has a white symbol on her black stockings, Yang has a black one in her default clothes and a yellow one on her Hunter outfit), or even with no colors (Summer's grave, Qrow's flask).
