Laurie, thank you so much for starting this thread. I've seen some of these before, some while they happened, and some I haven't seen. All of them are amazing and beautiful! The people behind the camera are all amazing too! Every person who socializes a feral deserves a medal for being so patient, so understanding, and most of all willing to listen to these amazing survivors to allow them to feel comfortable enough to let the walls down, learn to trust and learn to give and accept love.
I have two to share.

First is Ophelia who was definitely a feral kitten. She was stuck between the walls of our apartment building and thankfully in the wall by our bedroom. We guess that she was ~6 weeks old and
very independent, and had never seen a human before.
Then:

Now:

Annie isn't a true feral. She really didn't even have feral tendencies except that she didn't want to be confined in any way, but she is a rescue that I'm pretty proud of. Not because
I did anything special, but because a group of people most people would never expect came together to help one little kitty cat. She showed up at a rifle match in the middle of the Pike National Forest in the Rocky Mountains. All the guys helped out with her - one made sure I knew about her since he knew I was a cat lady, one had cat food in his truck (that one surprised me too!), another found a bowl and gave her water (there's no running water up there), another had a box, another (literally) gave one of the shirts off his back for her to ride back in comfort, and I brought her home.

Most people don't think of a group of tough, NRA-type shooters would give a kitten a second look, but it was as much them as me who made sure she was safe instead of being a light snack for something in the forest.
When I brought her home:

Now:

And yes, she still looks and acts like a kitten. She may not have been feral, but she sure wasn't able to
be a kitten until she came down the mountain when she was 6-8 months old.
