The 60-Second Answer

During an in-home pet sit, unexpected events are rare but possible: pet illness, injury, escape, household breakdown, or a sitter being unable to continue. The best way to manage these is to anticipate them before the sit with a comprehensive house guide, up-to-date emergency contacts, a veterinary care mandate, and a network of emergency support. This guide reviews the main unexpected events and the appropriate responses for each case, without venturing into medical advice, which remains the exclusive domain of the veterinarian.

This article is not a substitute for a veterinarian or a doctor. Healthcare decisions should always be made with a healthcare professional. For any life-threatening emergency concerning the animal, contact your veterinarian directly, 3115 (Veterinary Emergencies, 24/7, free) or CAPAE-Ouest (Animal Poison Control Center, 02 40 68 77 40, 8:30 a.m.-midnight). For an emergency concerning a person, 15 (SAMU) or 112 are the only correct responses.

Why Anticipating the Unexpected Changes Everything

Unexpected events are probably the least exciting topic to prepare for before a sit. We prefer to think about the upcoming trip, the friendly sitter we just chose, or the idea that everything will go well. And indeed, most of the time, everything does go well. But what makes all the difference between a serene sit and a traumatic one is not luck, it is preparation.

No reliable statistics exist in France on the rate of incidents in peer-to-peer in-home pet sitting. It is too recent and unstructured a topic to have generated its own data. But the experience accumulated by veterinarians, animal welfare associations, and matching platforms converges on a simple observation: a well-conducted preliminary meeting plus a complete house guide are enough to neutralize the vast majority of risks. Everything else is common sense and communication.

Out of the thirty-seven houses we sat with Elisa before founding Guardiens, we had our share of unexpected events: a cat that hid for three days after our arrival and was eventually found behind the washing machine, a dog that escaped through a poorly closed door then returned thirty minutes later, very proud, or an electric shutter that broke down on a Sunday evening during a storm. No drama, because each time two conditions were met: the owner had carefully prepared their guide, and we were reachable on both sides.

This article is a summary of what you need to know and prepare so that unexpected events, when they happen, remain unexpected and do not become catastrophes.

Le saviez-vous ?

The house guide that the owner provides to the guardian upon confirmation of the sit on Guardiens is probably the most crucial tool for preparation. It compiles all useful contacts, the animal's habits, and the specifics of the accommodation. The more complete it is, the less likely unexpected events are to escalate.

Preparing for the Sit: The Emergency Checklist

Eighty percent of managing unexpected events is done before they happen. Here are the six items to systematically put in place before each sit.

The Complete House Guide

This document, shared between the owner and the guardian upon confirmation of the sit, must absolutely contain:

The usual veterinarian: name, address, phone number, opening hours
3115 Veterinary Emergencies (free, 24/7) which connects you with an on-call veterinarian near your location via postal code
CAPAE-Ouest at 02 40 68 77 40 (Animal and Environmental Poison Control Center, free, 8:30 a.m.-midnight, 7 days a week) for any ingestion of suspicious products (plant, human medication, chocolate, rat poison)
The owner's phone number: direct + a secondary contact (spouse, parent, close friend)
A local contact: a trusted person, friend, or relative who lives within thirty minutes and can physically intervene in an emergency
The animal's health record: up-to-date, accessible (photo or scanned copy)
Current treatments: medication name, dosage, schedule, duration
Medical peculiarities: allergies, intolerances, chronic illnesses, at-risk behaviors
List of prohibited foods: chocolate, grapes, onions, and certain bones for dogs, lilies and leeks for cats

The Emergency Envelope

The owner provides an envelope with cash (200 to 400 € for a one to two-week sit with a single animal) or an available payment method (IBAN, Lydia, Paypal, prepaid credit card) so that the guardian can cover emergency expenses without advancing hundreds of euros out of their own pocket. The pre-authorized limit is clearly stated: "The guardian is authorized to incur up to X euros in veterinary expenses without prior agreement. Beyond this, mandatory contact is required."

The Veterinary Care Mandate

This is a short document (half a page is sufficient) that the owner signs before the sit, authorizing the guardian to take the animal to the veterinarian on their behalf and to authorize necessary care in case of a life-threatening emergency. Without this document, some veterinarians may refuse to treat an animal presented by someone who is not its owner. A template can be integrated into the house guide.

Trusted Artisan Contacts

Plumber, electrician, locksmith: three contacts included in the guide prevent the guardian from encountering an unscrupulous repair person in case of a breakdown. If the owner does not have any, an early search for Google reviews in their local area is enough to compile a reliable mini-list.

The Preliminary Meeting

This is the cornerstone of the entire process. A one-hour meeting at the owner's home, before the sit, where the guardian discovers the house, the animal, the routines, and the specificities. This is also the moment when trust is built between the two humans. Our guide on the preliminary meeting details the right questions to ask from both sides.

The Communication Channel

Before the sit, define the primary channel (SMS, WhatsApp, message in the Guardiens conversation), the frequency of updates (at least once a day), and the preferred time slot (e.g., in the evening after 7 p.m.). This avoids anxiety for an owner who does not receive updates and pressure for a guardian who is solicited at all hours.

Animal-Related Unexpected Events: 5 Situations and Their Responses

First and foremost: this guide never addresses medical procedures or emergency veterinary actions. Diagnosis and care are the exclusive responsibility of a professional. What we cover here is organization: who to call, in what order, how to communicate, and what to document.

The Animal Appears Sick or Injured

If the guardian observes something unusual: refusal to eat, vomiting, apathy, limping, discharge, whimpering. The rule is simple and has no exception: call the veterinarian.

For a worrying behavior during business hours, the guardian directly contacts the usual veterinarian indicated in the house guide. The veterinarian knows the animal, its history, and its current treatments. They will assess remotely whether a consultation, observation, or immediate action is necessary.

For an emergency outside business hours (evening, night, weekend, public holiday), 3115 Veterinary Emergencies connects you 24/7 with an on-call veterinarian near the sit's address, via postal code. The call and connection are free from any phone.

For ingestion of a suspicious product (plant, human medication, chocolate, rat poison, antifreeze), the immediate response is CAPAE-Ouest at 02 40 68 77 40, open from 8:30 a.m. to midnight, 7 days a week. The veterinary toxicologists at Oniris respond free of charge and provide guidance on what to do even before arriving at a veterinarian's office.

The guardian informs the owner immediately. For a non-life-threatening situation, a clear message is sufficient: "Hello, [animal's name] has not been well since this morning, [observed symptom]. I called the veterinarian, we have an appointment at 4 p.m. I will keep you updated after the consultation."

For a life-threatening emergency (convulsions, loss of consciousness, hemorrhage, severe respiratory distress, significant trauma), the guardian directly contacts the emergency clinic and notifies the owner during the journey or afterward, never before: the priority is the animal, not communication. And never hide an incident from the owner to avoid worrying them, even if everything turns out well. Immediate transparency is the basis of trust.

Escape or Animal Not Returning Home

A poorly closed door, a stressful event leading to hiding, a cat wandering too far to return on its own. This is a common anxiety during a sit, and it is managed systematically.

Within the first thirty minutes: the guardian circles the local area calling the animal, checks usual hiding spots indicated by the owner (under the sofa, behind the washing machine, in the attic), and notifies immediate locals. They keep a familiar item of the animal (blanket, toy) which facilitates recognition if it returns on its own.

Within two hours: if not already done, notify the owner. Post an announcement on local Facebook groups (with a recent photo, name, description, location and date of disappearance, and phone contact). Call veterinarians in the area (found animals are often brought to a vet). Call the municipal pound.

Within twenty-four hours: official reporting to the national database I-CAD (Identification of Domestic Carnivores). The owner can temporarily set the guardian's number as the emergency contact on the microchip for the duration of the sit, so that a veterinarian scanning the animal can directly call the correct person. Extend the search area.

An escape can happen even to the most attentive owners. Transparency and rapid mobilization save the situation in the vast majority of cases. No guilt, just action.

Unusual Behavior

The animal is more aggressive than usual, eats everything it finds, refuses to go out, or urinates everywhere in the house. Often, this is the stress of the owner's absence manifesting itself. This is temporary in most cases, especially if the animal met the guardian before the sit and routines are maintained.

Some good practices: do not punish (it makes things worse), maintain usual schedules (meals, walks, games), give attention without overdoing it, and inform the owner so they can reassure the animal remotely via call or video. Leaving an item with the owner's scent (an old t-shirt, for example) near the animal's sleeping area often helps.

If aggression becomes a safety issue (the dog growls, shows its teeth, bites seriously), it is more severe. The guardian immediately contacts the owner and considers a relay solution: a person from the owner's network takes over, or a Guardiens emergency guardian intervenes within a few hours.

The Animal's Death

This is the most dreaded and painful scenario. An elderly animal passing away peacefully in its sleep, or a serious accident that is irreversible. How to manage it?

At the moment, if possible, the guardian calls the owner directly. The moment they learn about it is important. Avoid written messages, which are brutal for this type of news. Prioritize a call.

Practically, according to the owner's wishes (to be requested in advance or indicated in the house guide), the animal can be taken to the veterinarian for cremation, or kept in cold storage until their return if the delay is short.

Legally, the guardian is not responsible for a death they neither caused nor hastened. Article 1875 of the Civil Code defines commodatum (loan for use) which frames the relationship: the guardian has an obligation of means, not of result. To engage their responsibility, one would have to prove a specific fault on their part (gross negligence, abandonment, mistreatment). An accidental death or death by illness does not engage their responsibility. To understand this framework, see our guide on the legal framework of house-sitting in France.

Humanly, the guardian may themselves be distraught by what they have just experienced. The owner must be aware of this and not project the grief of loss onto the guardian. It is in these moments that the trust built before the sit pays off: an owner who has met their guardian, discussed with them, and seen their relationship with animals, copes better with this tragedy.

Tense Situation with Another Animal

A rarer case: the guardian brings their own animal (a possible situation but one that must be explicitly validated by the owner before the sit, not announced upon arrival). If tension arises between the two animals (rejection, aggression), immediate separation into two different rooms is the first step. The owner is informed, and depending on the severity, either cohabitation resumes cautiously after a day, or the guardian arranges for a relay. Forcing cohabitation never leads to anything good.

House-Related Unexpected Events

The animal is fine, but the house is causing problems. Here are the most common cases.

A Household Appliance Breakdown

Water heater, fridge, washing machine, television: an appliance stops working during the sit. The guardian performs a simple test without dismantling (check that it is plugged in, that the circuit breaker has not tripped, that the water supply is not cut off). If that is not enough: take a photo, call the owner for a decision (repair now via a technician or wait until their return). The guardian never attempts to repair an appliance unless they have recognized expertise and explicit agreement from the owner.

A Water Leak

This is the breakdown that requires the quickest action. The guardian shuts off the water at the main stopcock (to be located in the house guide). Take a photo of the leak and its apparent origin. Call the owner and the trusted plumber if one is listed in the guide. In the absence of a designated plumber, search for an emergency local artisan. No repairs by the guardian unless they have recognized expertise.

A Power Outage

First reflex: check the main circuit breaker on the electrical panel (a tripped breaker can be reset with a simple gesture). If everything is in order at the panel, look out the window: if the locals and streetlights are also in the dark, it is a general network outage. The guardian then calls Enedis at 09 72 67 50 XX (XX = department number where the house is located). The Enedis breakdown service is available 24/7, free of charge.

If the outage lasts more than four hours, monitor the fridge and freezer (not opening them preserves freshness for several hours). For animal medications that must be kept cool (insulin in particular), notify the veterinarian for advice.

Burglary or Attempted Break-in

A fortunately rare case but one that deserves a clear protocol. The guardian's safety comes first: do not put yourself in danger, do not confront a burglar. Call 17 (Police) or 112 (single European emergency number). Once the situation is secured and law enforcement notified, call the owner immediately. Take photos for home insurance. The commodatum (loan for use that frames the sit) places the guardian in the same category as any regular guest: their insurance and the owner's cover standard situations.

Guardian-Related Unexpected Events

A frequently overlooked but very real topic: what happens if the guardian themselves falls ill or is involved in an accident during the sit?

A Minor Indisposition

A cold, headaches, temporary fatigue. Not enough to alert the owner or interrupt the sit. The guardian continues at a slower pace, spaces out walks, shortens outings. A mention in the daily report is sufficient: "Feeling a bit tired today, I took a shorter walk with [dog's name]. Everything else is fine."

An Illness Preventing Proper Animal Care

Gastroenteritis, fever, severe pain, a crushing migraine that keeps one bedridden. The guardian immediately notifies the owner. Depending on the situation, two options:

Hold on by reducing activity: if the illness is temporary (one to two days), maintaining the bare minimum for the animal (water, food, short walk if a dog) is sufficient.
Request a relay: if the illness lasts longer or worsens the situation, mobilize the owner's secondary contact indicated in the guide, or request a Guardiens emergency guardian.

A Human Medical Emergency

Discomfort, domestic accident, fall, loss of consciousness, chest pain, severe hemorrhage. Absolute priority: the guardian's health. There should be no hesitation, no cat is worth a human compromising their safety. Call 15 (SAMU) or 112 without delay. Once the guardian is taken care of, their relatives or healthcare providers notify the owner, who then arranges for a relay via their personal network or through the platform.

The guardian remains under their own social protection scheme (Social Security, mutual insurance) wherever they are in France. Commodatum has no impact on this coverage. A consultation, hospitalization, care: everything is covered as it would be at their usual domicile. If they are in a different region than their usual doctor, they can consult in town (on-call doctor, medical center) or at hospital emergency rooms depending on the severity.

The Guardiens Emergency Guardians Network

For all necessary relay cases (sick guardian, accident, unforeseen personal event), Guardiens activates an emergency guardians network: verified and experienced guardians (at least five complete sits, average rating above 4.5/5) who can intervene within hours in most major French urban areas. The owner makes their request from their space, and Guardiens prioritizes contacting available emergency guardians in the geographic area of the sit.

Transparency Above All Else

The common thread through all of the above is immediate transparency. Hiding an incident from the owner to avoid worrying them is the worst thing to do. Even if everything turns out well, the omission definitively breaks trust. Conversely, notifying immediately, explaining what has been done, and asking for help when necessary: this is what allows a sit to go well even when the unexpected occurs.

On the owner's side, transparency works both ways: reporting anything out of the ordinary before the sit (anxious animal, house with peculiarities, ongoing treatment), providing access to all useful information, and not minimizing an animal's fragility to facilitate matching. A guardian who discovers an unannounced problem during the sit has the right to terminate.

FAQ

Should the guardian have animal first aid training?

No, it is not mandatory and it is not the guardian's role. The guardian's role is to identify that there is a problem and to call the right contact (usual veterinarian, 3115, CAPAE-Ouest). Diagnosis and care remain the exclusive responsibility of professionals. Training can be a plus, but it does not replace a call to the veterinarian or a care mandate.

What to do if the owner does not respond during an emergency?

Precisely for this reason, the house guide contains a secondary contact (spouse, parent, close friend) and a pre-authorized limit for veterinary expenses. The guardian calls the secondary contact, and if the emergency justifies it, initiates care within the limit with the care mandate. Everything is documented (invoices, exchanges) and transmitted upon the owner's return.

Is the guardian responsible in case of an animal's escape?

No, unless there is a specific fault (gross negligence, intentionally left an open door, abusive behavior). Article 1875 of the Civil Code places the guardian under an obligation of means, not of result. An accidental escape despite normal vigilance does not engage their responsibility. Transparency and rapid mobilization to find the animal are expected, not infallibility.

Is specific insurance required for house-sitting?

For peer-to-peer sits via Guardiens, each party's usual civil liability insurance covers the vast majority of situations. Commodatum does not require dedicated insurance. Check with your insurer that civil liability is active outside your usual home (this is generally the default case).

How many emergency contacts should be in the house guide?

At least five: usual veterinarian, 3115, CAPAE-Ouest, owner, owner's secondary contact. A sixth is recommended: a local person (within thirty minutes) who can intervene in an emergency where the guardian needs concrete help.

Frequently Asked Questions

Foire aux questions

What should I do if my pet falls ill during a sit?

Immediately contact the reference veterinarian listed in the house guide. If the situation is urgent and no clinic can be reached, call 3115 (on-call veterinarians) or CAPAE-Ouest at 02 40 68 77 40 in case of suspected poisoning. Notify the owner via Guardiens messaging immediately afterward and keep all care receipts for reimbursement.

How do I manage a water leak or breakdown during house-sitting?

Turn off the water supply or the relevant circuit breaker, then consult the "Emergencies" section of the house guide which contains the contact details of the plumber, electrician, or building manager to contact. Inform the owner by message, attaching a photo of the damage. Do not attempt any repairs outside your area of expertise.

What happens if I need to cut short or interrupt the sit?

Notify the owner as soon as possible via messaging. Guardiens offers an emergency network that can activate a qualified replacement guardian. The owner is notified immediately and can approve the replacement from the application. Document the transfer of instructions in writing.

Who is responsible in case of material damage during the sit?

Article 1875 of the Civil Code (commodatum) frames the guardian's responsibility: they must use the item with reasonable care and return it in the same condition. Accidental damage is generally covered by the owner's home insurance or the guardian's civil liability. Report the damage to your insurer within 5 working days.

How should I react if the animal escapes or disappears?

Immediately trigger the procedure: verify that the microchip is up to date on the i-cad.fr portal, contact veterinarians, city halls, pounds, and shelters in the area. Post an announcement with a photo and description. Notify the owner and post on local groups. Keep a record of all your actions.

The owner is no longer responding to my messages, what should I do?

Maintain the sit under the agreed conditions and continue to send regular updates via Guardiens messaging (timestamps serve as proof). If the situation extends beyond the scheduled end date, contact Guardiens support, who can activate a protection procedure (for the animal and housing) and identify a local close to the owner.

Am I covered if I injure myself during the sit?

The guardian remains responsible for their own safety. Before the sit, check that your personal civil liability insurance (included in most home insurance policies) covers damage caused to others. For physical injuries, your health insurance takes over. In case of emergency, dial 15 or 112.
