Praying for Raven's return.
My sister's house was recently broken into. Both cats ran outside and hid for hours. We called and called for hours and they eventually came home. You could try leaving some clothes that smell like you (dirty clothes basket works great) outside near your front door. Please keep us posted.

If she's not back soon, this website has some helpful tips.
