Have you posted flyers with this information and his picture?  That is a
good way to get the attention of people in the area.  Be sure to post them
in a fairly broad perimeter around your home.  A notice in your local
newspaper would also be helpful -- and, of course, telephone calls to the
neighbors.

Getting out and talking to people could sure be a good idea - just talking
to people walking around in the neighborhood could be a good idea.  If
you have a picture and/or poster it could help to be able to show people.
And going out again and again to talk to people that you did not talk to
before.

Also going out and calling your kitty when it is quiet can find a kitty,
because the cat can hear you and may not be so confused by other sounds.
