When I first got my cat, he was 2 years old and he did hide for a few days. He hid under my waterbed. I talked to him when I was in the room, but I left him alone, I didn't try to force him out. After a couple of days I saw him peeking out at me, I think he was curious. So I opened a can of tuna and fed him tiny bits, gave him lots of petting. He warmed up pretty quick after that. He was such a good cat - he was so affectionate he was more like a dog.
