Very sad that you are missing your sweet baby. Sending prayers and checking back often. Years ago, when I had a male cat named snowball, he snuck out the door, he had been an indoor kitty. I went door to door and talked to the homeowner and left a picture of him, I taped the flyer to the door of those that did not answer. I did this through my whole neighborhood, it was exhausting, plus I had my little son. The cat showed up on his own that same evening. My feet forgot the pain they were in the moment I heard him meow.
Praying for your baby to be with you soon.
