What this authorisation has to do in a high-rise emergency
Emergency authorisation for a cat staying in a city apartment with a balcony on the ninth floor exists for one pressured moment: something has happened, you may not answer immediately, and the person in charge must be able to get the cat assessed and treated without losing time proving they are allowed to act. Write it as a short, signed, dated-in-words statement naming the cat, naming the person authorised, and stating plainly that they may consent to emergency veterinary examination and stabilising care for this cat during the stay. In this address the defining emergency is a fall or suspected fall, so the document should say explicitly that any fall from height, even one where the cat walks away apparently unhurt, counts as an emergency requiring prompt veterinary assessment, because internal injuries and fractures are not always visible at first.
The details a vet and the carer both need on the page
List your own phone number and the order in which to try contacts, a second named person who can also make decisions if you are unreachable, the regular vet's name, address, and number, and the nearest out-of-hours emergency service to the apartment, which may not be the regular vet at night. Add the cat's microchip number, age, known health conditions in plain language, any regular care the vet should know about, and vaccination status. State how payment will be handled in general terms you have agreed in advance, such as the carer paying and you reimbursing, or the vet contacting you directly, so money questions never delay the cat being seen. Note the carrier's location in the flat and that the balcony door stays locked, since a frightened, injured cat may bolt toward familiar exits.
Scenario wording specific to this apartment
Generic authorisations fail by saying nothing about the actual risks of the place. Here, name them: a fall from the balcony or a window, an escape onto the shared landing or into the lift shaft areas during an evacuation, and injuries from household hazards such as a washing machine or recliner mechanism. Give the carer permission to use a taxi or car service to reach the emergency vet if that is fastest, and to consent to the cat being kept in for observation if the vet advises it. Also state what you want to be told and how quickly: a call at the time of the incident where possible, followed by the vet's findings, rather than a summary at the end of the week.
Limits, clarity, and keeping the document findable
An authorisation is clearer when it also shows its edges. Say that it applies only to this stay and this named carer, that routine non-urgent matters should wait for your input where the cat is stable, and that if you and the second contact are both unreachable, the carer may follow the vet's advice on urgent care needed to prevent suffering. Write in plain sentences, avoid abbreviations, and keep the whole thing to one page that can be photographed and sent to a vet. Leave printed copies with the carer and by the carrier, and store the same wording digitally where the carer can reach it at midnight without asking you for a file.
Pairing the authorisation with the daily routine
The authorisation works best alongside the ordinary care notes, because the vet will ask what the cat ate, whether behaviour changed, and when the incident happened, and the carer answers those questions from the routine record. Check before the stay that the carer has actually read the fall instruction and knows the emergency vet's location, not merely that the paper exists. With KinsLe Care Pass, the named carer holds temporary access to the authorisation details, the cat's routine, and your contact order together, so the high-rise plan is in hand when it is needed.
