The cat came back...a month and a half later...he didn't know the song apparently

Well I have some really great news, Tarzan came home! We were watching a movie and he jumped up in the window, at first we weren't sure it was him, but we could tell by the crooked tail that it was him. And when Mom called his name he came running to the house. The bad part is, because Casey is in the house now, we can't let him back in, because dad doesn't want three cats in the house.
