Does your cat respond when you call their name?

My cat had many names. Officially she was Meowmeows, but she was often called just Kitty or Putti Tat. (My dad started that). She seemed to know when we were talking to or about her I'm not sure if she knew her names really or if it was just her awareness that our attention was directed at her. Like most cats she would often "ignore" us, but usually her ear would twitch so your knee she was listening to you, even if she was pretending to be oblivious and ignoring you.
