I am not sure that you entirely understand what that second picture, the one of Scotty, actually shows. This is a cat who, until very recently, was at best a stray, at worst, semi-feral, and in a very short time you have him not only enjoying affection, but willingly and happily exposing his belly while in your lap. That is phenominal. There are those of us who have had our cats since kittenhood, and they've never been totally comfortable with that. ALL of these cats are becoming socialized far more quickly than anyone could have expected. I'm not entirely sure what you and Alpha Kitty are doing, but you have evidently stumbled onto a system that works very, very well.
