What to leave a pet sitter: the complete checklist

The difference between a calm pet-sit and a 2am phone call is the handover. Here's everything a sitter actually needs — and how to hand it over without a five-page email.

There is a particular kind of holiday anxiety that has nothing to do with flights. It is the moment you hand your keys to a sitter and realise you have thirty seconds to explain a life. Which door sticks, which pill hides in which treat, what the limp means, who to call.

Do the handover well and you genuinely stop thinking about it. Here is what actually belongs in it.

The four things that matter in an emergency

Everything else is comfort. These four are the ones that decide how a bad night goes. The American Veterinary Medical Association's guidance on care while you are away is blunt about all four:

  1. How to reach you — every method, not just one number that might be on airplane mode.
  2. Your vet and a 24-hour emergency clinic — names, numbers and addresses, because the regular practice may be closed.
  3. A named decision-maker and a spending limit. Choose someone who can authorise treatment if you cannot be reached, and agree how it will be paid. The AVMA suggests arranging a payment method in advance and even warning your card issuer, so an unusual charge is not declined as suspected fraud at the worst possible moment.
  4. What you would refuse. Be explicit about any treatment you would not want authorised without speaking to you first.

The daily routine

This is what makes the sit calm rather than merely survivable:

  • Feeding — how much, how often, what times, and what absolutely not to give. In a house with more than one animal, say clearly who eats what and where, so nobody gets double-fed or eats another pet's diet.
  • Medication — the drug, the dose, the time, and the trick that actually gets it swallowed. Note anything that must be given with food.
  • Toilet and exercise — walk times, lead or off-lead, the dog who bolts at cats, the litter tray that needs scooping twice a day.
  • Normal versus not-normal — the behaviour that is just your pet being your pet, and the specific signs that mean call the vet. This is the hardest thing for a sitter to judge and the most valuable thing you can write down.

Access and household logistics

  • Keys, alarm codes, and which door to use.
  • Where the food, litter, leads, medication and cleaning kit live.
  • A backup human — a neighbour or friend who can get in if the sitter is locked out or unwell.
  • Bin day, thermostat, the window that must stay shut.

The mistake almost everyone makes

The instinct is to write everything, and the result is a document the sitter skims once and never reopens. When the dog is being sick at midnight, nobody scrolls a twelve-page WhatsApp. Lead with the four emergency items and the daily routine; keep the deep background available but collapsed.

This is exactly the problem Tailtend's sitter link solves. Instead of a five-page email, you create a single secure link scoped to sitter view: your sitter sees the emergency contacts, feeding, medication and routine laid out clearly, without seeing your billing or being able to change anything. From the app it is one tap — Create a sitter link — with a sensible thirty-day expiry, and it revokes the moment you are home. Set one up before your next trip.

If part of your trip prep is a vet check first, our guide to what to bring to your pet's next vet visit pairs well with this one — and if you are juggling several animals, so does keeping everyone's medications straight.

Frequently asked questions

What is the single most important thing to leave a pet sitter?

A named emergency decision-maker and a spending limit. The AVMA recommends choosing an authorised agent who can consent to treatment if you cannot be reached, and agreeing in advance how veterinary costs will be paid — this is what prevents a delay in genuine emergencies.

Should I give my sitter permission to authorise veterinary treatment?

Yes, within limits you set. Tell them your vet and emergency clinic, agree a cost ceiling above which they must try to reach you first, and be explicit about decisions you would not want made without you. Many clinics also have their own emergency authorisation form.

How much detail is too much for a sitter?

A twelve-page document nobody reads is worse than one clear page. Lead with the emergency contacts and the daily routine; keep the background detail available but out of the way. A sitter needs to find the vet's number in five seconds, not read an essay.
