This might be a dumb suggestion, but Ive found it works on the new kitties we end up with. When making eye contact with the cat, blink softly. Its a non-threatening gesture and appears to work to help relax your new cat. I did this with our newest acquisition, Bones MD. He was terrified of me and would not come out of his carrier at first. Just sitting with him and talking softly and doing the blinking thing worked wonders. The next day, he was way more accepting of me. Now, I cant get him out of my way lol.
