I have just been handed over care of a 4 year old very feral cat. He cannot be lot less because he came here because he was very beaten up. He is neutered and physically better but very scared. I have him in a quiet room by himself and he is eating and drinking but cries at night. Initially he appeared in shock and I touched him but he now hisses if I try. I have backed off and let him spend time with me and my saintly pet cat who will purr and talk to him. I spend an hour in the morning and an hour and a half in the evening reading and just hanging out. He is finally coming out to eat with me in the room as long as my cat is with me. He cries at night and appears lonely. What more can I do?
