This time, having gotten my act together, the new cat --Obi--has walked out of the bathroom and around the livingroom. Currently hiding between the kitchen wall and stove. No harm can come of that. Sniffed noses with the other cat again got a small hiss out the other cat--first time I've heard him do that. He never dared with the Little Old Cat, she'd have sent him flying..
And he's out of the kitchen--record time so far. Looks willing to accept under the plant table between 2 bookshelves (neatly blocked off from digging him out the first time around).
I do believe we have a keeper.
 

Still not eating. Didn't touch his wet food either. Soooo, we had a small force feeding session of kibble. He took it well enough. Maybe he'll get the idea that it's okay to eat. I did warn him that I can and will do whatever is needed on any given topic. The hazards of being owned by an old Vet Tech: nothing sacred.

Well. We must be feeling a little better: the new boy just hissed and took a swing at the Old Boy. Proved he's a bit of a klutz by falling off the windowsill tonight. Still not eating on his own yet beyond a few mouthfuls of wet food--not good for his teeth that. Still haven't figure out his preferred eating schedule. Thought he showed signs of wanting a late night munchie by his dive for the Old Boy's food dish: presented him with his own dish: nope. The hiss/swing might have been one of those subtle things about who gets to pass who in the hall too. Just can't tell.
