Found Cat!!

My neighbors and I found a cat outside our building this evening. One of my neighbors says she thinks he has been there for a few days (her dog was interested in it last night).

He is very friendly, comes over to people and allows them to pick him up, and purrs when petted. He has a mark where a collar has been, so I think he is lost or else was evicted from his home recently. He is orange and white, an adolescent, and very sweet.

If anyone knows where this adorable cat may have come from, or has an idea about where it can find a loving home, please let me know. He seems very healthy and doesn't seem to have any health issues, and is only a little skinny, so I don't think he's been outside very long. He is currently living in my second bathroom, but I don't know how long I can keep him.
