You mainly just have to have patience. I've tamed a few cats, but it took months. I just kept feeding them, and getting closer and closer eachtime. I also let them know that it was feeding time in a soothing voice, so that overtime, they'd learn to recognize my voice.

I agree with everyone else, use caution around your cats. He can be diseased. Oh, and don't do what I did with one wild cat...tried to catch it with my bare hands. I still have scars to from that one. lol.
