Start with the microchip registry and the collar tag
A Domestic Shorthair's paperwork after a move begins with the two records a finder will actually use. Update the microchip registry with the new address and the phone number you will answer during moving week, and ask for written confirmation of the change. Replace the collar tag at the same time, and check that the tag's number matches the registry. Because Domestic Shorthairs are the most common type of cat, a finder may meet several similar short-coated cats in one street, so the tag and registry entry do the identifying work that appearance alone cannot do.
Give the new veterinary clinic a clear picture
A Domestic Shorthair has no breed-standard coat or build to explain her, so the written record matters even more than it does for a purebred cat. Send the new clinic her vaccination history, any past illness or injury notes, and the name of the food she eats. Add a recent photograph and a plain description of her colour, markings, size, and temperament, including whether she is shy with strangers or bold enough to approach them. A new clinician reading that description can tell at a glance whether the cat in the carrier matches the file, and can spot a change in weight or condition against a solid baseline.
Update the files that are easy to overlook
Beyond the vet and the chip, work through the files that quietly carry the old address. Update any pet insurance record, any boarding or grooming registration, and any local pet licence or registration where one applies. If a delivery service brings her food or litter, change the delivery address before the first order after the move, and tell any regular sitter or neighbour who holds a spare key. Give that person a fresh emergency sheet with the new address, the new vet's name and number, and a note about where she hides when the house is noisy, since a Domestic Shorthair under moving stress often retreats to a cupboard or under a bed.
Keep a moving-week folder by the carrier
On moving day itself, keep one folder beside the carrier with the microchip confirmation, the vet summary, the new tag details, and the updated emergency sheet. Include her feeding times, her litter setup, and the name of the room she will be confined to while doors stand open. Movers, open doors, and unfamiliar rooms are a classic combination for an escaped cat, and a folder you can grab in seconds beats a drawer you have to search. If she does slip out, the folder gives searchers her current photo, her markings, and the phone number that reaches you, rather than an old address from a previous home.
Finish by checking every change once more
A week after the move, re-check each updated record, because a hurried online form is the easiest place for a digit to slip. Confirm the microchip registry shows the new address, confirm the new clinic holds the full history, and confirm the insurance and boarding files agree with each other. File the corrected copies together so the next sitter, boarder, or clinic visit starts from one clean set of papers instead of a fresh hunt. KinsLe keeps that habit simple, because a Domestic Shorthair's Pet Passport in KinsLe gathers her records into one portable packet that travels with her to the new home and beyond.
