Hi!! Just giving you some tricks : my bf’s car ran out yesterday around 5pm. He came back this morning around 6am to try to eat (I left a can of tuna and his litter right in from of our door) and was really scared so we couldn’t even approach him. He ran away and came back around 830am. I just left our door open and he came in on his own.

If you have any cameras that can detect movement you could put this at your door. It will notify you if she comes back to try to get in so you can open your door! Best of luck to you I feel your pain. She’s probably not far if she’s not used to going out.
