I speak Polish and although my Polish-English dictionary translates the word kitka as aigrette I only know it to mean ponytail.
This is the wiki entry for the word aigrette(I wasn't familiar and I'm not sure if other people are or not)

I suppose it could be used as a diminutive nickname for something. In Polish it would certainly sound ridiculous as a name.
