Josie: From a book I was reading at the time...can't remember the book now...
Zeke: TV show Tour of Duty
Kiba: A tv show Wolf's Rain (kiba was a wolf. means fang)
Butter: I couldn't find a fitting name for him. I "named" him Shadow because he follows me everywhere, and he's black...but I call him Butter...which just seems to fit him even though I don't think it's a suitable name for a Black male cat?? lol
