TC: so sorry and keeping you and her in my thoughts; I hope she makes her way home soon. Is she microchipped or ID tagged? Have you posted any signs up for her? Females, I think, tend to stay closer to home, but maybe post some signs all over. I hope she finds her way home soon! Sending you hugs.
P.s. Check EVERY nook and cranny; cats are amazingly good at squeezing into tiny spaces.
