He keeps coming around but gets scared off anytime we go near him. Looks a little thin like he could use a good meal. I'm going to keep trying every time we see him he stays a little longer.
What I've done in the past to make new furry friends is when I'd see them, I would put a few treats out and back away. Don't leave, just hang back far enough and sit down so the kitty feels safe enough to get the treat while still seeing that you were responsible for it. Next time do the same thing, except slightly closer. Rinse and repeat until the cat starts feeling comfortable around you and associates you with tasty treats. Don't try and give them too much attention, let them have time to trust you. Sometimes it works right away, some cats take a few months. One stray cat took me nearly two years before I could pet her. ( She is sleeping on my couch right now.)
It doesn't work 100%, some cats are just a little too sketched to trust people, but I've made friends with around 25 cats in the last 7 years that way. There's a lot of strays around here, I've been taking them in and getting them fixed as money allows. (about 14 of them so far, been concentrating especially on the girls to stop the kitten problem)
