Well, the police called. They found an old record of his owners but they are not answering the phone and do not have an answering machine. And I guess they can't give me any of their personal information.
I just fed him, and he ate it all. Also noticed he has a white stripe on his chest. He's a really sweet boy...
The police said they will keep trying to call and let me know, if they can't get ahold of him they will send an officer to come get him and bring him to the local vet (whom i am good friends with).
