Names for new Kitty??

Im planing on getting a cat soon.I havnt decided if im going to get a kitten or an older cat or a boy or girl but i do want to get a black cat.Im trying to think of cute names that arnt too popular(so nothing like shadow or spooky or stuff like that).So far i like Ninja but i dont know if that would work for a girl cat.What do you think?Also any other name suggestion for a black cat would be great.Thanks so much.
