The short answer, and a chooser by situation
Pick the least disruptive arrangement that still gives your animal the supervision it needs. That sounds like a dodge, but it's the shape of the evidence: nobody has tested whether sitters, daycare, boarding kennels or sitter-home boarding produce better outcomes for pets. What exists is a handful of small studies, expert guidance from veterinary and welfare groups, and plenty of opinion from people who sell one of the options.
So skip "which format wins" and ask which one suits this animal on this trip, and how you'll check the person or place you're handing them to. Most of the work is in the checking. The table below is a starting point built from the guidance we read. It's judgement, not a tested decision rule.
| Your situation | Lean towards | Why |
|---|---|---|
| A few hours, or a run of long workdays | Daycare or a drop-in visit | Nobody needs to be there overnight. |
| A trip of a night or more, healthy and sociable dog | Facility boarding or sitter-home boarding | Staff or a household are around all day and night. |
| Anxious pet, or one on time-sensitive medication | Overnight sitter in your home, or a vet-run facility | American Humane describes overnight care as suited to anxious or medically complex pets; VCA recommends veterinary-hospital boarding for elderly or medically complex ones. |
| More than one pet, or a mix of dog and cat | Check the setup closely | Multi-pet feeding needs a plan whoever is doing it. See multi-pet feeding. |
| A cat | Read the cat section below | Cats have their own evidence and their own checklist. |
Five things people call "pet care"
Most comparison pages fold these into "sitter" or "boarding," but they're different services with different risks. American Humane's guide draws several of these lines, and VCA's veterinarian-written guide separates traditional boarding from in-home boarding.
| Format | What it is | Who is with the animal overnight | What the evidence shows |
|---|---|---|---|
| Drop-in visit | A sitter comes to your home once or more a day to feed, walk and spend time with the pet | Nobody | Expert guidance only. No outcome study found. |
| Overnight sitting | A sitter stays in your home while you are away | The sitter | Expert guidance only. No outcome study found. |
| Sitter-home boarding | Your pet stays in the sitter's own home (VCA notes this is usually dogs, not cats) | The sitter's household, and possibly their other animals | Expert guidance only. No outcome study found. |
| Facility boarding | A dedicated facility: a veterinary office with boarding, a pet hotel or a specialty kennel | Depends on the facility, so ask | A small number of dog and cat studies, covered below. |
| Daycare | A facility where dogs spend the day and go home in the evening | Not applicable | No welfare-outcome study found. AAHA lists daycare among settings that raise disease exposure. |
"No outcome study found" is a limited result, not proof of absence. We searched PubMed titles and abstracts (a limited search, run 29 September 2026) for dog daycare, pet sitters and boarding catteries and found no welfare-outcome study of daycare or sitters. If one exists, we'd like to add it. Until then, everything below about sitters and daycare is guidance from welfare groups and veterinary sources, not measured results.
Does boarding stress a dog?
The best evidence we found says "it's complicated," and nobody can put a percentage on it. Owners want a number. Any page that hands you one is inventing it.
The clearest study is Part and colleagues, 2014, in Physiology & Behavior. It followed 29 privately owned dogs, comparing each dog at home and in a boarding kennel. Stress-hormone measures (cortisol and VMA relative to creatinine) were higher in the kennel than at home, and exercise didn't explain it. The dogs were also more active in the kennel, with "considerable individual variability." But the authors wrote that the "emotional valence of responses was ambiguous and no definitive evidence was found to suggest that dogs were negatively stressed by kennelling." Their reading was that cortisol was tracking arousal, not necessarily distress.
Cortisol rises when an animal is excited as well as when it's frightened. A 2019 review by Polgar, Blackwell and Rooney makes the same point about kennelled dogs and adds that, because cortisol is affected by arousal, sex, age and time of day, "it is not currently possible to determine such a cut-off value for unacceptable welfare." That is why a headline like "boarding stresses dogs by 40%" can't be honest, and why a low reading doesn't prove a happy dog either.
One more study comes with a caveat. Rooney and colleagues, 2007 moved 31 one-year-old male Labradors into a working-dog training kennel (not a commercial boarding kennel). Cortisol rose in every dog, more in dogs not previously used to kennel confinement, and stayed above baseline 12 weeks later in that group. It's one study of working dogs, so read it as "prior familiarisation was associated with a smaller rise," not as proof about boarding. Familiarise your dog before a long stay (see the ladder below), and watch how the dog eats, rests and settles afterwards. For a dog who already struggles when left alone, the separation anxiety guide covers what helps before any stay.
Kennel cough, in plain terms
A vaccine lowers the odds you'll need to worry about kennel cough, but treat it as one layer, not a guarantee. Nothing in the AAHA wording we read says a vaccinated dog can't catch it.
"Kennel cough" is a common name for infectious respiratory disease in dogs. Several germs can be involved, and the vaccines AAHA discusses cover Bordetella bronchiseptica, canine parainfluenza and canine influenza. In the AAHA 2022 canine vaccination guidelines, Bordetella, Lyme, canine influenza and rattlesnake vaccines are all "noncore": "recommended for some dogs based on lifestyle, geographic location, and risk of exposure." For dogs whose lifestyle carries that risk, AAHA's FAQ says they are "just as essential as the vaccines that are required for all dogs."
On boarding specifically, the wording is hedged. AAHA says "for patients at high risk for CPIV and Bb, it may be advantageous to use IN combination Bb and CPIV vaccines more frequently than annually, for example, before boarding." That's about vaccine frequency for high-risk dogs, not a rule that every boarded dog needs a shot.
Two clarifications, because this gets misquoted. The sentence you may have seen ("at or before entry") comes from the shelter section of the guidelines, not the boarding section, although that section adds that boarding kennels "should consider following the same vaccination protocol." And AAHA does not recommend canine influenza vaccine for all dogs; the decision should follow current local circulation. Its FAQ lists boarding, daycare, dog parks, shows and travel as risk factors, and lists "boarding in kennels or attending dog daycares" as a risk factor for leptospirosis too. That's a second vaccine question for your vet, no more.
Your part is simple. Ask your vet about vaccine timing for your dog, given where you live and where the dog is going. Then check the facility's own rules, which are the facility's and may go beyond AAHA's wording. If your dog develops a cough after a stay, call your vet. Trouble breathing, collapse, or pale or blue gums is an emergency: go to an emergency clinic instead of waiting. The watch-versus-emergency guide shows how this site draws that line for another common risk.
For prevention that boarding facilities and sitters often ask about, see parasite prevention by season and region.
Sitter or cattery for a cat
No study compares cat sitters with catteries, so no honest page can say home is better or worse. What exists is one older study of catteries and design guidance from a cat-welfare charity.
The study is Kessler and Turner, 1997, in Animal Welfare. It is a Swiss study (Cambridge is only the publisher) of 140 boarding cats over a two-week stay, scored with a non-invasive stress scale and compared with 45 shelter cats. Stress fell over the stay, most sharply in the first days, but had not reached the shelter group's level by the end of week two. In week two, "the average stress level of about one third of all boarding cats was rated higher than 'weakly tense'," with 4 per cent rated even higher, and the authors concluded that for those cats the two-week stay "was classified as inappropriate." About two thirds adjusted well. Single, paired or group housing made no difference to stress, and neither did age. We read the abstract only, so nothing here goes beyond it. It's a 1997 study of one type of facility. Treat it as a reason to check and to choose by the individual cat, not a verdict.
What a good cattery looks like. International Cat Care (updated 26 September 2025) is the strongest cat-side guidance we found. It's a charity's guidance, not a trial, but it's specific:
- Individual, escape-proof units, with a "safety corridor" or controlled-entry area outside each one and staff who follow door-closing rules.
- An impermeable "sneeze barrier" between units, and no communal runs where cats from different households share space.
- Current vaccination certificates required, and cleaning you can have explained to you.
- Individual runs of roughly 6ft by 4ft (1.8m by 1.2m) as an example size, with shelves and hiding places.
- No barking dogs nearby: "Barking and excited dogs in kennels near a cattery can be very stressful for cats."
- The same food as at home, daily monitoring of eating and toileting, and a vet consent form plus your emergency contact.
- A visit before you book, watching whether the cats look relaxed.

If you choose a sitter, everything under "what to check" below applies, and the owner-side list in the ASPCA's pet-sitter guidance is the one to copy: how to reach you, an itinerary, emergency contacts who can make medical decisions, the pet's age, weight, health issues, medications, diet and microchip details, your vet and emergency clinic, medication instructions covered in person, the daily routine (including an anxious cat's hiding spots) and a clear emergency plan. Ask the sitter how visits work at the door, since an escape is the risk many cat owners worry about, and whether they'll do a trial visit with you present.
Multi-cat homes and bonded pairs. International Cat Care describes individual runs except for bonded housemates. If your cats live together, ask any cattery how they house pairs. For getting a cat to a cattery without a bad start, see cat carrier stress.
What to check in a provider, and how sure we are
This checklist is drawn from veterinary, humane-society and charity guidance plus common sense. It's a practical checklist, not a studied protocol. No study has tested whether asking these questions leads to better outcomes for pets, and most checklists you'll find are written by someone who sells one of the options.
The sources are American Humane (a vetting list), VCA Animal Hospitals (veterinarian-written, from a commercial hospital chain) and, for cats, International Cat Care above.
| Ask a facility | Ask a sitter (visits or overnight) |
|---|---|
| Are you licensed and inspected where we live? (Rules vary by place; we didn't check yours, so ask.) | Can I speak to current clients as references? |
| Does my pet get private quarters, with separate resting and eating areas? | Are you trained in pet first aid or CPR? |
| How do you reach a vet in an emergency? | What is your emergency plan, and who do you call? |
| What is your staff-to-animal ratio, and who is on site overnight? | Do you have other clients over my dates, especially if my pet needs medication at set times? |
| What are your vaccine rules, and how do you handle a sick animal? | Will you meet my pet before day one? |
| Can I see the premises, and are the other animals healthy and vaccinated? | How do you handle keys, doors and gates? |
| Do you keep a written log of my pet's eating and toileting? | Can we do a short trial visit first? |
On staff ratios. American Humane lists the staff-to-animal ratio as a question to ask, but we found no authoritative number for what it should be, so we give none. Ask each place, compare the answers, and notice how the person responds to being asked.
Red flags, using only what the guidance above supports: a sitter who won't meet your pet before day one ("worth reconsidering," in American Humane's words), no references from current clients, no emergency plan or first-aid training, and other clients booked over your dates when your pet has timed medication. On the facility side, a place that won't let you see where your pet would stay, or can't say how it reaches a vet. These are reasons to keep looking, not a scoring system.
A first-stay ladder
Stage the first stay so a bad surprise happens on a short visit, not on day four of a two-week trip. The steps below are our own practical sequence. The meet-and-greet and on-site visit are backed by the guidance above; the exact order, and the single-night trial, are judgement.
- Meet-and-greet. Meet the sitter, or tour the facility, with your pet if allowed. Ask the questions in the table.
- A short visit or one night. Book a short stay before the long one. For a cat with a sitter, ask for a trial visit while you are there. Note how your pet eats, rests and greets you afterwards.
- The real stay. Hand over the details (see below) and keep your goodbyes brief.

What to hand over. Use the ASPCA list above: contacts and itinerary, your vet and emergency clinic, age, weight, health issues, diet and routine, and medications with written dosage and timing. Then talk through the emergency plan out loud.
What to watch afterwards. Appetite, toileting, energy, and any cough. Call your vet if your pet isn't back to normal within a few days or if a cough appears. There's no evidence-based number of days here, so use your own judgement of what's normal for your pet.
Adding up the real cost
Compare totals, not nightly rates. We give no prices, because we found no independent source for them and quotes vary by place and season. What we can give you is a tally to fill in with your own quotes.
For each option, write down: the base rate multiplied by the number of nights or visits, plus any required extras (medication, extra pets, a bath or a walk), plus holiday surcharges, plus transport to and from, plus a contingency for a vet bill or a trip that runs long. Then compare the totals. Drop-ins that look cheap per visit add up over many days, and a facility that looks pricey per night may already include the extras.
Bottom line: the format matters less than the provider and the preparation. Shortlist one provider, do the meet-and-greet and a short trial, ask your own vet about vaccine timing if you have a dog, and bring your vet's contact and consent details if you have a cat. Nobody has tested whether the checklist works, so treat it as good practice, not a promise.
FAQ
Is a pet sitter better than boarding?
Neither is better across the board. We found no study comparing outcomes for sitters, sitter-home boarding, daycare and kennels. An overnight sitter keeps a pet in its own home, which suits some animals; a facility has staff and a vet nearby, which suits others. The provider and the preparation matter as much as the format.
Is doggy daycare safe for every dog?
We found no welfare-outcome study of dog daycare, so nobody can honestly say it is safe or unsafe for every dog. The AAHA vaccination guidelines list daycare among settings that raise exposure to canine influenza and leptospirosis, so ask your vet what your dog needs.
Does my dog need the kennel cough vaccine to board?
That depends on the facility's own rules and on your dog's risk, so check the facility's requirements and ask your vet about vaccine timing. AAHA classes the Bordetella vaccine as noncore, meaning recommended for some dogs based on lifestyle, location and risk, and says it may be advantageous to vaccinate high-risk dogs more often than yearly, for example before boarding.
Is a cat sitter or a cattery better?
No study compares the two. The one boarding-cattery study we found (Kessler and Turner, Switzerland, 1997) followed 140 cats; about two thirds adjusted well over two weeks, while about a third were still rated above weakly tense in week two. It can't say home care is better. Choose by the individual cat and use the checklists above.
What are the red flags in a pet sitter?
American Humane says a sitter who won't meet your pet before day one is worth reconsidering. Other flags follow from its vetting questions: no references from current clients, no emergency plan, no pet first-aid training, or other clients booked over your dates when your pet needs medication at set times.
How long before a trip should I book a trial stay?
There is no evidence-based interval. Earlier is easier, because it leaves time to fix whatever the trial shows. Treat this as practical judgement, not a studied rule.
