Loki must be a very friendly kitty and not much frightens him.
Our cats will run when the doorbell rings, but as soon as the people come up the stairs into the living room, they'll come back out. And as soon as they sit down on the sofa or the chair, our kids check out their laps. Thankfully nobody minds having a lapful of cats. The only one who hides is Amber.
Although Amber is getting more social. I think the best things that happened to Amber are Mollipop and Tabby because they've brought her out of her shell a bit. She doesn't spend her time back in the bedroom anymore; she'll come out to be with us more often.
When Rick was in Oregon a few weeks ago, my BIL stopped in at night to help me clean Tabby's ears. Now, years ago, the whole time somebody was in the house, Amber wouldn't come out; she'd stay back in the bedroom. Now? She came out to greet my BIL and even sat on the sofa with him and let him touch her. He was amazed.
Our Phantom Kitty isn't such a Phantom Kitty anymore.
