How to find a missing cat?

my I year old unaltered cat went missing 12 days ago, the day he went missing is the day I scheduled him to get neutered ironically. He was mostly an inside cat, but as he got older he started going outside more, but he never seemed to stray very far away. There are other cats on my street who also go outside, and they are still around, but I have to say, I think they are all fixed I am so worried about this cat, I don't understand how he could just disappear like that! Ive asked some of my neighbors, Ive been to the shelters, put ads on craigslist. I don't know what else to do!!

Have you tried putting up posters and offering a reward to anyone who finds him? This will save you a lot of time going around town yourself looking for him 100+ eyes are better than only 2. I really hope that you find him x

The little guy is the right age to start looking for a social life. Sometimes cats go off and hide for a while, then one day they'll show up again. If there are any buildings he can get under or places he can hide like a wooded area check them and put some food outside overnight and watch to see if it's eaten. You might include a note promising to call off the neutering if he'll just come back home. :-)
