Passing through?

I happened to glance out the window this afternoon and spotted this little black kitty. She didn't come to me but she also didn't run away from me. There were several bowls of dry food outside because we had been away for a few days, so I knew if she was hungry she could find something. Later in the day I saw her in close proximity to two of my other cats, so there doesn't seem to be conflict. I don't mind feeding another outside cat.
