She's certainly a beautiful cat, and thanks for sharing this story.
My Human used to be one of the volunteers who helped care for a feral cat colony that lived in a greenbelt near his place of work. To whatever degree possible, they would be caught, given shots, spayed/neutered and set free again; similarly, kittens (when any happened) would be rounded up and either adopted out, or allowed to live with the colony... pretty steady at 30-40 cats. Some of them got tame enough that they could be petted and picked up; most would just come close when there was extra kibble offered, but keep their distance.

It's actually amazing how many of those were once pets and they become quite traumatised out on the streets but can often be tamed again. I have a few of those, too. Good on your human for helping to take care of a colony
