Thanks to Diane for calling me, to see if it might be my Angel. Unfortunately, it wasn't...but I did find out more.
The guys at Tuffy's didn't know anything about it, but the peeps next door at Back Yard Burgers confirm that they have been leaving food out for it for months. They do not think it belongs to anyone and are afraid that it will get hit someday. They told me that if I could catch it, I could have it but that the cat was a bit wild (not feral, just not used to humans). Of course, I couldn't get it to come closer to me. I threw a few kitty treats and it did eat them, and once it acted like it was about to get a little closer, but then turned and dove into the landscaping by Southern Resorts.
I'd go down every evening and work on getting its confidence and taming it a little, but I live too far away. It is beautiful, and needs a safe home!
