We brought our 5 year old rescue cat home yesterday and he's barely emerged from behind the sofa since! At the rescue centre he was friendly and affectionate. Just hoping for some reassurance that this is normal behaviour. He's confined to one room at the moment (kitchen/diner) and has eaten and used his litter box. We're in and out of the room, chatting to him, but it's a quiet household so no great hurly-burly to scare him. Our previous cat (RIP) was a stray who we adopted overseas and was the most confident, sociable cat on the planet - never known to hide away anywhere, so I'm not used to this. Is there anything I should do to help the new arrival settle, or just leave him in peace?
