NextDoor app is your best chance as covers your area. Be sure to check your local animal shelter in person (can’t stress enough - in person!!! You know your pet best plus shelter workers are busy and can’t keep up) every couple days. Follow your pets routine, as weird as it might sound, as this sometimes help. Create a scent station with items that have your smell,your cat’s smell. Bedding, clothing, cat tower, etc. and have someone check in and under everything with a flashlight. Cats don’t go far and freeze in a tight ball in very small areas when scared. But they stare which is where the flashlight comes in handy. Catches the glare of their eyes, especially at night. Pray your baby is home safe and soon.
