With my cat we really didn't have any issues naming her, we have given her the name of Kiki. Since the name sounds sort of like kitty kitty, she knows it and comes running when we call her. I have seen someone mentioned something about specific sounds when calling your cat, I think this to be true as they learn your voice and know when to come if they are used to it. Cats are smart creatures believe it or not and can learn pretty fast when it is meal time for them or when you are trying to get their attention, however sometimes they will ignore you just because they don't want to come or pay attention, the thing with felines is that sometimes they just want to do their own thing.
