I need some advice. I caught a cat a month ago which I thought was a shy stray, but I think may really be feral. I got him neutered and I've been trying to socialize him and get him to trust me but he has not made any progress at all. He is still terrified of me/other people and very unhappy being indoors/near people. He just wants to get away from people. I'm not sure what the best thing to do is, since he is so unhappy I don't know if I should keep trying to socialize him or if I should release him, I don't know what would be best...
