I've moved a thousand times with my 15yo cat, and he has always been confined to the laundry for about 24hrs... Then allowed into the bigger areas like Lounge n dining room but we keep the bedroom doors shut for a day or two, then let him in our bedroom n bathroom and by then he is fine. He's done heaps of moves tho so adjusts really well. Just take it slow for her, let her into new areas bits at a time...
