Health Records the New Owner Needs From Day One
The core of the handover is her health history. Pass over her vaccination card or record showing what she has had and when boosters fall due, a summary from your vet of recent visits, test results, and any conditions being monitored, and clear notes on anything ongoing, such as a special diet, a recurring ear problem, or a daily routine she relies on. A new owner who knows what is normal for her can spot changes quickly, and a new vet who receives real history instead of guesswork can continue her care without repeating tests she has already had.
Ask your clinic, before the move, for a printed or emailed summary if the full file is scattered across years of visits. Vets produce these routinely for exactly this situation, and requesting it a week ahead is kinder than asking on handover day itself.
Identity and Registration: Chip, Papers, and Proof
Her microchip details must change hands as a formal step, not a verbal aside. Give the new owner the chip number, the registry name, and whatever transfer form or code the registry requires, and agree who initiates the transfer and by when, because until it completes, a scan still points to you. Keep your own copy of the number and confirmation until you have evidence the record now names the new keeper.
If she has registration or ancestry papers, those originals go with her, along with any breeder contract terms that affect her, such as a neutering agreement. Note insurance too: say whether a policy exists, whether it can be transferred or must be ended, and give the new owner the insurer's details so there is no silent gap in cover while paperwork catches up with the move.
The Written Knowledge Only You Have
Documents from clinics and registries say what she is; a page from you says who she is. Write down what and how much she eats, the foods she refuses, her litter and tray habits, where she likes to sleep and hide, how she behaves at the vet and in a carrier, and the fears and comforts you have learned, from a hatred of the hoover to the blanket that settles her. This sheet is often the most used document of all in the first fortnight, because it lets the new home feel familiar to her faster.
Be honest in it, including about difficulties. A cat rehomed with her challenges described kindly and accurately has a far better chance of settling permanently than one whose new owner discovers them unprepared and feels misled.
Agree the Handover Itself in Writing
Put the practical frame in writing as well: the day and time she moves, what comes with her, from carrier and bedding to remaining food, and who is responsible for her care and any vet costs up to that moment. If the rehoming involves a rescue, follow its own paperwork and keep copies of everything you sign. Retain your copies of the health and chip documents until the transfer is confirmed, then pass or destroy them as agreed, since her records contain your personal details too.
Moving her details across through KinsLe Transferrable Profiles means her profile, history, records, and routines transfer to the new owner intact in one handover, so the knowledge you have built up over her life arrives with her instead of depending on a folder changing hands.
