Amanda ~ I recommend you go to the shelters and fill out lost pet forms.
You need to look in every cage because just in case. They sometimes keep cats in the infirmary. Make sure you look there too and even the dog cages. Ask to look at their found cat forms. Sadly, look at the DOA files. Time of the essence. Unless you go and check for yourself, you're relying on the overworked volunteers at the shelter to do the search for you know your kitty better than anyone.

There are also some good ideas here: http://www.petrescue.com/petlibrary/...st-cat-or-dog/

Sadly, we found that our cat (Kuhio) was put to sleep at our shelter because we didn't find her in time. Please go to all shelters close to your area and make friends with the volunteers there. They will help you if possible. Go door-to-door in your neighborhood, our neighbor 4 doors down had called the SPCA thinking our kitty was abandoned. We were out of town and by the time we found out, it was too late.

Please keep us posted.
