Here's some vibes coming your way, hoping for your kitties safe return.
Have you been calling for her? (here kitty, kitty, kitty!)
(When I first moved into my house, I had 3 cats, one of whom had been an outdoor cat hanging around my old apartment whom I'd adopted. I kept Tina inside for the first 2 weeks, then let her go out for a little while. She disappeared. I tried to find her for 3 days, looking at the old apartment (5 blocks away), going door to door.
Then on the third day, I paid a bit more attention to this kind of woodsy area a block away (which has since had many trees removed by the owner) that would tempt me if I were a cat. I walked down to it, and started calling Tina. Then I heard a meow. Then I saw a small, fast, furry black streak running across the front of the woodsy area. She was there, but not coming closer, more like shadowing my walk at a distance, as if she were asking me to come join her in that cool woods rather than coming to me. I kept calling her and walking towards home, and she finally followed me.
Also, when I was a kid, our cat Tiger ran off and was gone for a couple of months. We thought it was the end of him, but one day, there was a frantic scratching at the back door. We opened it, and Tiger came running in, then went straight to the basement. He didn't seem any worse for wear, but must have decided 'there's no place like home'!
