A house move is the perfect storm for a disappearing cat: doors propped open at two addresses, strangers carrying furniture through her territory, hiding places dismantled around her, and a new home whose smells and exits mean nothing to her yet. When she cannot be found afterwards, the search has an unusual shape, because she may be at either end of the move, or travelling between them.
Search Two Homes at Once
Start by searching two homes at once rather than assuming she escaped at the new address. At the old house she may have slipped out during loading, or hidden so thoroughly among boxes and empty cupboards that she was left behind in silence. At the new house she may have bolted during unloading, or be immured behind a bath panel, inside a wardrobe void or under floorboards disturbed by the move. Search both properties room by room, calling quietly and then listening, with a torch for voids, and check garages, sheds and outbuildings at each end.
Alert and leaflet both addresses' neighbours on the same day. The two streets hold different people, different gardens and different sheds, and a leaflet at only one address covers only half her possible hiding places. Include the other address on each leaflet, because a finder at the old house needs to know she now belongs across town.
Fix the Records: Registry First, Confirmed by Read-Back
A move breaks paperwork as surely as it breaks routines. Ring the registry and move the record to the new address and your current number, then ask for a read-back of the details held under her chip number so you know the record itself changed. Be precise about the mechanics: a scan yields the chip number only, the registry holds the contact record, and updating a KinsLe profile does not update the registry. A cat found after a move is exactly the cat most likely to be scanned, and a record still pointing at the old address, or at a phone number you no longer have, can strand her in a rescue while you search.
Tell your old and new veterinary practices, and any local rescues, at both ends of the move. If she is handed in anywhere, a current record is what brings the call to you.
Keep Checking the Old Home Over Following Days
Have the old home checked again over following days, as she may travel back. Cats who escape at a new address sometimes navigate towards the territory they know, and cats left hiding at the old address emerge once the house is quiet and empty. Arrange access with the new occupants or the agent, leave your number with the old neighbours, and ask them to check sheds and garages repeatedly rather than once. Set the same quiet routine at the new house: food and a familiar-smelling blanket near the door she likely left by, checked at dawn and dusk.
