Quite a while back I posted some information and tips on finding lost pets. If I did this right, this link should bring you to my old post.

If the link doesn't work (and I wouldn't be surprised since I'm pretty much a computer illiterate!), my post is in the "A good friend needs our help" thread in the pet section.
I sure hope you find your fur-baby safe and sound soon!
As a side note, here in MA we have a Saber Alert System - not sure how it came to be, but from what I understand it can be pretty successful.
