Put her litter box, some food and something with your scent on it outside to help her find her way back. Generally they don't go far and will squeeze into tight spaces when scared. Check with neighbors, in garages and sheds, piles of rubbage, bushes, trees, everywhere. Put on Nextdoor. And put flyers up around the area. Some people don't do social media. I hope Tigy is back home safely soon.
