OMG!!
I pray for the safe return of your fur babies!
Have you contacted all rescues and shelters in your state and near by states? You can find a list of them all at www.petfinder.com. Also make sure to post an ad for your Lost furkids on Petfinder.
There are a lot of web sites you can post a missing pet on.
I'd do a Goole search to find them all.

I wish you good luck!
