Something similar happened to Jasmine's sister a couple of months ago. The woman who adopted her let her run outside (with the difference that this woman was not a good mom, we know it by now) and the poor little girl was about 4 months old and not very strong yet. On one side of the house there was a big road and on the other side there was a wood. We never thought that such a young cat would come back, and she did! 24h after she escaped she was back meowing at the front door!!

I just want to say that there is still a great chance that she comes back, Gary. It should be terrible for you at the moment but you must believe in it!
(((Hugs))) and POUNCIERGE, PLEASE COME BACK!
