Any particular sounds she is used to hearing that she may come to?
Yes, she generally responds to the sound of food in her bowl when it’s rattled. I have tried that around the neighborhood during the day and evening.
Good idea; when my neighbor told me one of my cats escaped when I was out of town I told her to turn the TV on and leave the window open. BTW it didn’t work; but 1 day after I came home she showed up, I think because she saw my car.
