G. is resting comfortably on my bed with the door open, a good sign. He spent this morning cowering under D's bed and part of the afternoon in D's bathroom. But he seemed much too curious and wanted to be let out, so I let him out. Then he came into my room, explored a bit, leaped onto the bed in that graceful Siamese way, put his head down on his paws, and dozed.
O. came in just a few minutes ago to check out G.'s food and water dish (I've had to squirt him with the water bottle three times to keep him away), and G. didn't hunch up like he did before. He was calm.
Granted, the cats are still on opposite sides of the apartment. But I'm seeing some good signs. The only worrying part so far is that G. hasn't eaten since he's been here. That, and I've been sneezing like crazy today. I hope it's just a one-day thing. (Please?)
He's really very friendly and affectionate. I hope he can stay.
