Kimlovescats, kittens can be unpredictable at times, concerning their acceptance of humans, especially when they come from a background like the one you have. Give him time, a place to run and hide, and also give him something to eat that he cannot resist, like tuna. I have found that by giving a cat, in a strange place, with new people, some special treat, can do much to correct their behavior into what we are looling for.
