Two cats, two owners, two separate permissions
A home caring for a cat temporarily for a deployed owner already operates under one set of instructions written by someone who may be very hard to reach. Your cat arriving for a week creates a second, independent line of responsibility, and the emergency authorisation is where that line is drawn. Nothing in the deployed owner's paperwork covers your cat, and nothing in yours should claim to cover theirs. Write your authorisation as a self-contained document: your cat's name, description, and microchip number, your name as owner, the carer's name, and a plain statement that the carer may consent to emergency veterinary examination and stabilising care for your cat during your cat's stay.
Contact order designed for people who may be unreachable
This household is already used to an owner who cannot always answer, so design your contact order to be stronger than that pattern. List your phone first and say how you can be reached during the stay, then name a second decision-maker who is local, awake in this time zone, and genuinely empowered to make choices with the vet if you cannot be reached. Add a third practical contact, such as the local person who could collect or transport the cat, if that differs. Give the regular vet's full details and the out-of-hours emergency service the carer should use, and note which carrier is yours, labelled with your cat's name, so two cats' equipment never mixes during a rushed departure.
Keeping the two cats' medical stories apart at the vet
At a clinic, confusion is the risk this household adds. Your authorisation should carry your cat's own facts only: age, known conditions in plain language, vaccination status, microchip number, and any regular care the vet should know, with a heading that makes clear these details belong to your cat. Ask the carer to keep your document in a separate folder or wallet from the deployed owner's cat's papers, and to photograph your page so it can be shown at reception even if the folder is left behind. If both cats ever attend the vet around the same time, the carer should present each cat with its own paperwork and confirm names and microchip numbers aloud at check-in.
Deployment-specific edges to settle in advance
Talk through the uncomfortable scenarios before the stay, because deployment households think in contingencies and will respect directness. What if the carer themselves has an emergency and both cats need temporary cover? Name the backup person for your cat. What if your return is delayed while the carer is managing the deployed owner's long-term arrangements? State how extra days of care and any vet costs for your cat are handled in general agreed terms. What if the deployed owner contacts the carer midweek with urgent instructions for their cat at the same time yours is unwell? Agree that each cat's own authorisation governs its own care and that your second contact can step in for your cat. These conversations feel excessive until the evening they are needed.
A document the carer can actually use under pressure
Keep the authorisation to one page, signed, with the urgent-care permission, contact order, and vet details impossible to miss, and rehearse it briefly at handover: the carer reads it back, confirms the carrier, and confirms where the folder lives. Ask for same-day notification of any incident involving your cat, however minor it seems, so you are never reconstructing events at collection. Using KinsLe Care Pass, the carer keeps temporary access to your cat's authorisation summary, routine, and contacts as a clearly separate set from the deployed owner's cat's information.
