Wow, what a list! I hope it isn't too late to add to this: Our female cat was called Trey by our daugher, but her nickname is Treybabe(yes it is my user name on this site) and our male cat is Billy Bob but I call him Bees or Beebop and sometimes Bittles. Can't say why. For a while our two year old grandchild called him Beely the Bope, so we called him that too. Fun!
