OMG, I have tears streaming down my face. I can't believe his reaction to seeing you. I've only seen one other person have that kind of relationship with their cats.
I'm sorry for Ruthie that it didn't work out, but I am SOOO happy Amos is home where he belongs. You did try Katie, know that. Amos knows you saved his life over a year ago and he's not going to trust anyone but you.
Welcome back home Amos!!
