A moved cat does not need the run of the whole house on arrival; she needs one room she can learn completely. Choose a quiet room away from the front door and the unpacking traffic, close its door, and set it up before she comes out of her carrier, so her first exploration is of a finished, calm space rather than a room changing around her.
Setting Up the Base Room
Place her litter tray in one corner and food and water well away from it, in line with how cats prefer to separate toileting from eating. Add a scratching post, a hiding place with an opening she can slip into, and bedding carried from the old home unwashed, because familiar scent is a strong signal that this room belongs to her. Put a perch or a sturdy box near a window if the room has one, and let her leave the carrier in her own time, with the door shut and the household asked to knock and enter slowly.
Spreading Her Scent for Her
Cats claim space by rubbing their cheeks and flanks on edges, leaving scent that tells them the place is known and safe. Help that process along once she is rubbing furniture willingly: take a soft cloth, stroke it gently over her cheeks a few times, then wipe it along door frames, table legs and the corners of furniture, working at her head height in the base room and, later, in each room as it opens. You are not scenting the house for her instead of letting her work; you are laying a faint familiar trail she can build on, and her own rubbing on top of it is the sign the room is being claimed.
Opening the House One Room at a Time
Add roughly one new room a day, and only move on when the current territory looks owned: she eats there, uses the tray without hesitation, explores in daylight rather than only at night, and rests out in the open. Let her enter each new room empty of people first, with boxes in that room unpacked or pushed aside, and keep the base room available as a retreat she can return to at any point. If a room unsettles her, close it again and retry the next day; a slower map that holds is worth more than a fast tour that ends with her hiding behind the washing machine.
Helping Her Through a Setback
Expect a wobble or two in the week: a room she entered happily on Tuesday may worry her on Wednesday after a delivery, a slammed door or a visitor's voice. Do not carry her back into that room to show her it is safe, and do not close her into it to force the issue. Simply leave its door open, let her retreat to the base room for as long as she chooses, refresh the scent cloth on its frames that evening, and let her re-enter in her own time, which she usually does once curiosity outweighs the scare.
Keeping the Old Clock Running
Hold her previous feeding times, play sessions and bedtime pattern steady through the whole week, even when your own schedule in the new home is chaotic. Meals arriving at the hours her body expects, a play session with her usual wand toy before the evening feed, and lights and noise dropping at the familiar time tell her that daily life itself has not changed, only the walls around it. Postpone visitors, new pets and redecorating in her rooms until the map and the clock are both settled. Relatives you select can be given access to her profile through Family Sharing on KinsLe while the new map is still forming.
