That was very sweet of you to do this for this poor little girl. She is very lucky that she does not have to scrounge for garbage. She reminds me of a little feral girl that I have, her name is Arwen, and she was also a garbage can scrounger who lived in my neighborhood for years. She only was ever seen at nights when the garbage was put out, and never would eat any food I left next to the garbage can. One day though, she finally took some canned food I left her, and soon showed up every day. When she finally got close enough, I thought her ear was damaged from fighting, and well, partially it was, but it was obvious that she was a TNR. Big relief! It took months before I could even touch her, and almost a year before I could pet her on her back. She will not come inside my house, but she does sleep in my garage in the winter, when it gets cold outside. She is outside my front door every morning. It's been over three years that we have been taking care of her. She is also very close with one of my neighbors and their dog. They walk their lab every night, and she walks with them. We all guess that she may be 5-8 years or even older. She is kind of rough looking, but I just love her. I always wish I could make her an inside cat, but she has no desire to come inside, and I already have 4....yes 4 cats, inside. And trust me, I did not want 4, but they were all helpless and found me.
You did a good thing getting this girl off the streets and scrounging for her meals from the garbage cans.
