Call ALL of the local animal rescue/animal control/etc. every single day. The staffs are very, very busy and won't necessarily remember your lost cat if he gets brought in if he is not microchipped or tattooed (in the ear). An email with a pic they can print out, or take one of your flyers to every single one of them. Ditto with taking your flyers to all of the local vets.
If your cat is microchipped or tattooed, make sure your information in their system is up-to-date and correct, and you notify them your cat is missing. Some assist you looking, some send texts to members/vets/etc., some help with flyers/posters, some will provide a reward, etc.
Post to petfinder and any local online lost/found pet websites/facebook pages.
Talk to the local police, especially an officer that works late at night. He or she may have seen your cat and know a general area... give the police your flyers for their desk book/roll call/patrol cars... if you are near the border of more than one police jurisdiction, take flyers to the one(s) that are really close to yours.
If your cat is out and about, he may be hunting and eating mice and birds, and actually be doing fine, sugar-wise
I highly recommend everyone get their cat(s) (and dog(s)) microchipped, as it means a much greater chance of kitty (or puppy) being returned home
