I have two feral cats, 16 and 12 years old. They are very friendly to us. They don't like anything to be moved and freak out when we do any home improvements. My Daughter has a feral cat, she got as a tiny kitten, he has spent his whole life (16 years old) Totally scared to death of humans. He hisses when someone walks by him. They have tried to get him use to him but no luck. She wonders if she did him any favors by taking him in.
Cute kitties and I hope you can get them use to you. They may hide when company comes.
