Hi Sofi - I also have had the joy of domesticating a feral kitty - my Panda Bear apparently was abandoned as a little kitten. It took all spring, summer and fall to finally get close to her and I did it by talking softly to her, just sitting and watching her without making any sudden moves and enticing her with food. I'd try and get her to take a few treats from my hand until I finally got her to trust me enough so she'd let me pet her. Sounds like your kitty has had a rough life though - it may take a little longer to gain his trust. Don't try and make him do anything he doesn't want - I think he's already distrustful because you trapped him and sent him to the vet which definately had to be done, so it will probably take awhile for him to trust you enough to get close to him. But it will happen, just takes time. Hang in there! You've done a wonderful thing!!!!!
