Not too much to tell today. The cats seem to be relaxing further, progressing steadily. There have been a few more encounters at the gate with no hissing or growling.
Last night was a bit rough as James actually slept in the bedroom instead of in the office with his cat, so there was a bit of yowling, but we ignored it and eventually it stopped and everyone got to sleep. I know this sounds mean to some people, but it actually is the best way to handle an animal who is crying when you know they're not hurt or sick. Going into the room every time they cry not only reinforces the behavior because you come when they wail, but it also doesn't allow them to find out that they are, in fact, going to be okay if they are left alone.
So there was one little call down the hall to let the cat know someone was still here, then we stayed silent the rest of the night.
Simba didn't seem bothered at all by the yowling. Slept through most of it from her cat bed in the living room, I assume, since she didn't even make her way back to the bedroom until much later and I heard not a peep from her. She didn't cry at all when she came back, just sat at the cedar chest at the foot of the bed and went back to sleep.
James left the house for a couple of hours today so I slipped in to spend a little time alone with Anubis, to make sure he knows even when James isn't here I am safe to be around. He's still wary but coming around. I'm sure part of it is a bit of backslide because the new surroundings smell like me, and I also smell like that other kitty that hissed at him. But I have been petting them both, going back and forth between the rooms and getting their scents on each other a little bit. I think that should help, if they smell it on themselves and come to realize the "other cat" smell isn't a threat.
But they don't seem to be acting completely scared of each other anymore, nor are they acting aggressive at all. Both cats do still act a little wary when they catch sight of each other, but nobody has been running away. They'll stare for a minute then turn and walk off. Every so often Simba still comes to me for reassurance that I still love her even though there's another kitty. But those times are becoming fewer and fewer as we go along.
Only 3 days in and everybody's making loads of progress. Which is a good thing, because I think "mom" and "dad" will be a LOT calmer once the cats have settled in. It's quite clear they are going to be fine, but it will definitely feel better once we've completed the process and everybody's comfortable.
