The Number Is Only Needed When Everything Is Already Going Wrong
A sitter rarely needs a microchip number during a normal stay. They need it if your cat slips out during a visit, is found hurt and taken to a clinic, or is picked up by a rescue that scans her and finds registry details that need confirming quickly. In that moment, a printed copy inside the care folder at your home can be read aloud over the phone by anyone in the house, with no battery, signal, or login standing in the way. The digital copy does the opposite job just as well: the sitter can forward the exact number, digit for digit, to you or to the clinic holding your cat, with no risk of a misheard digit in a stressful call.
Number and Registry Name Must Travel Together
A chip number on its own is only half the information. Different registries hold different records, and the registry name tells a vet or rescue where your contact details actually live. Write both on each copy, exactly as they appear on your registration confirmation, and add the registry's contact route you would want used. Before you travel, check the registry record itself: owners are often surprised to find an old phone number or a previous address still listed, and a sitter holding a correct number cannot fix an out-of-date record behind it. If you have recently moved or changed numbers, update the registry first, then print fresh copies.
Where Each Copy Should Live During the Stay
Put the printed copy in the front of the sitter's care folder, not loose among feeding notes, and tell the sitter it is there before you leave — a document nobody knows about helps no one. The digital copy should sit in the same message or shared note as the rest of the emergency details, so it can be found by searching your cat's name rather than scrolling weeks of conversation. Do not pin this number on a public-facing sheet like a feeding whiteboard in a window-facing kitchen; it belongs in the care folder and the sitter's phone, where the people who may need it can reach it and strangers cannot read it in passing.
Agree What the Sitter Does With It
Talk through the missing-cat sequence while you are still at home: the sitter calls you first, searches the immediate area, then contacts your vet and local rescues, giving the chip number and registry name so any scanned cat can be matched to you without delay. Make clear the sitter should never hand the number out casually or post it publicly in a lost-cat appeal — public posts need your description and a contact route, while the chip number is the private proof used by clinics, rescues, and registries to confirm identity. That distinction keeps a useful safeguard from becoming a risk.
A Two-Minute Check Before Every Trip
Chip details go stale quietly, so fold this into your packing routine: read the number on your printed copy against the registry record, confirm the registry name is spelled as the registry spells it, and replace both copies if anything changed. KinsLe's Care Pass gives your sitter temporary, clear access to your cat's key details, including that chip number and registry name, while you are away — so if the worst day comes, the information is already in the right hands in both paper and digital form.
