The one thing not being taken into account here is the home itself and its owners.

Cats tend to adopt something of their owners' personalities. So some take to other cats while some don't. My cat is territorial and challenges any cat who comes around. If he sees a cat in the yard, he immediately wants to go out and not to say hi either. He's come in with big swatches of fur missing from his paw, head, back, tail, breast--he don't care. I'll let him outside and then I'll hear a cat-fight 10 minutes later. He's rowdy. Like me, he wants the place to himself and isn't about to share it with anybody.

But the lady next door, as I said, has cats and she has that cat-person air about her. She'll come out on her porch and he'll be sitting on one her porch chairs grooming but she never gets mad or shoos him away and he'll let her pet him. He doesn't submit to that from people usually. So she could probably take him in if she wanted to but there is no way he'd ever let most people near him. I can't even get a finger on him when he doesn't want me to.
