Two weeks away is long enough for a small contact problem to become an emergency of its own: a sitter who cannot reach you, a vet number copied wrong two years ago, a neighbour who held a spare key and has since moved. The list that matters is not the one saved in your phone from the last trip but the version the person feeding or boarding her will actually see, so rebuild it around this trip, this carer and this cat, and treat every entry as suspect until you have checked it.
Who belongs on the list while you are away
Start with yourself, twice over: your mobile, and a second route to you — a partner's number, the hotel, or a messaging account you will check daily — because signal fails on holiday more readily than cats do. Next comes this trip's carer, named as a contact in their own right rather than buried in a note, whether that is a sitter visiting daily or the cattery holding her for the fortnight. Add a trusted nearby person who can physically get into your home, ideally the keyholder, because a voice on the phone cannot let a vet or a plumber through the door. Finish with the veterinary side in two parts: your usual practice for ordinary hours, and the out-of-hours service that covers nights and weekends, since a cat rarely chooses office hours to become unwell.
Test every number before you pack
A list nobody has dialled is a draft, not a safety net. Read the finished version back digit by digit against the sources the numbers came from, then send a short test message to the carer and the keyholder so a transposed digit shows up now, while it costs nothing. Tell each person they are on the list and what you would ask of them — nobody should learn they are an emergency contact from a stranger's phone call at midnight. Note beside each entry when that person is reachable and who to try next if they do not answer, so the carer never faces a dead end with a sick cat in the carrier.
What sits alongside the numbers
Contacts alone do not authorise anyone to act, so give the list a short supporting cast. Add a line granting the carer permission to seek emergency treatment and naming the practice to use, plus any current medication with its times, her feeding routine in plain words, and anything a stranger handling her should know — that she hides from visitors, or bolts for open doors. Write down your return date and the times you will be unreachable in transit, and keep her microchip details with the list so identity questions have an answer that does not depend on reaching you.
Do the refresh in one sitting, a few days before you travel rather than on the morning of departure, and leave the finished list where the carer will genuinely find it. With the checking done, her records sit ready in KinsLe — the Pet Passport carries those refreshed contacts alongside her vet history, so nobody caring for her works from an old printout.
