WOW!!! That sure is one very beautiful kitty! What a face!

Be patient with him and keep doing what you're already doing. Unfortunately, there's no way of knowing what this poor kitty has been through and if he has ever had a bad experience with some uncaring human. It will take time for Hunter to learn that he can trust you and you won't do anything to hurt him. Given time, he'll respond to your love but it has to be at his pace.

PS: I love your siggy with the surfing kitties!
