Is she an anxious sort of cat? If so I would probably confine her for a few days...If she is not a skittish or anxious cat, probably the first day and night in the one room, then let her explore under supervision the house just so she doesnt go hiding where you cant get to here. You really have to play it by ear with cats, she might surprise you and be really cruisy with it all....we had a cat we brought back from NZ with us many years ago, we just kept him inside for about 3 days then let him explore the outside. He promptly disappeared for another 3 days little bugger....but came home again, he was just checking out the neighbourhood I guess.
