For a trip of 3 days or less, the least disruptive option is almost always a sitter who comes to your home once or twice a day. For a week or more, boarding or a live-in sitter starts to win, and flying with the cat is rarely worth it unless you are relocating. The choice matters less than the handover: most problems that show up on your return trace back to missing information, not to which option you picked.

The short answer by trip length

1-3 days: one 30-45 minute visit a day, plus a second short visit if the cat is under 1 year, over 12, on medication, or eats wet food that cannot sit out. Cats handle solitude far better than dogs, but 24 hours with no human checking the litter box is the practical ceiling for a healthy adult.

4-7 days: two visits a day, or a live-in sitter. Two visits catch a problem within 12 hours rather than 24, which is the difference between a cat that skipped a meal and a cat that has not eaten in two days.

Over 7 days: boarding becomes competitive on price once you add 14 visits plus travel fees, and it removes the risk of a stranger holding your keys.

What an in-home visit should cover

A 30-minute visit is enough for one cat if the sitter does five things: fresh water in a washed bowl, wet food served and removed after 30 minutes, litter scooped with the clumps counted, 10-15 minutes of active play, and one photo of the cat standing up. The photo matters more than it sounds: a cat photographed upright and forward-facing is behaving normally; a cat flattened in a corner is not.

Ask for the urine clump count in writing. An adult cat on wet food usually produces 2-4 clumps a day, fewer on dry. Zero clumps over 24 hours is a same-day vet call, not a wait-and-see, because a blocked cat can go from uncomfortable to critical in under 48 hours.

Boarding and the infection math

Boarding puts your cat in a building with other cats' stress, scent, and viruses. Feline herpesvirus and calicivirus survive on hands, bowls, and cage latches, and upper respiratory infection is the most common thing a cat brings home from a cattery. Solid dividers, separate air handling, and disinfection between guests all reduce the risk; nothing removes it.

Boarding suits a cat that already travels well, tolerates handling, and has no chronic condition. It is a poor fit for a cat on insulin, a cat with a history of urinary blockage, or a cat that stops eating when its routine changes. In an overweight cat, 24-48 hours of not eating can trigger hepatic lipidosis, a genuine emergency that often starts with something as ordinary as a strange room.

Taking the cat with you

Flying: most airlines allow one cat in cabin per passenger, in a carrier that fits under the seat, with a total weight limit around 8 kg including the bag. Book the pet space when you book the ticket, because cabin slots are capped per flight. A health certificate is commonly required within 10 days of travel. Cargo is a different risk category: noise, tarmac temperature swings, handling by strangers. Most feline-only vets advise against cargo for cats over 10 or with a heart murmur.

Sedation: your vet may prescribe gabapentin, often around 100 mg for a 4-5 kg cat, given 1.5-2 hours before departure. Do not test the dose for the first time on travel day; give it once at home a week earlier so you know whether your cat becomes calm or agitated.

Driving: carrier secured as for any vet trip, familiar blanket inside, last full meal 4-6 hours before departure, a 15-minute break every 2-3 hours. A cat loose in a moving car is a projectile, and a cat loose at a rest stop is a lost cat.

The handover sheet

Write it, print it, tape it inside a kitchen cabinet, and send a photo to the sitter. Verbal instructions do not survive a stressful first visit.

ItemWhat to write
FoodBrand, exact grams per meal, times, where the scoop lives, what not to substitute
MedicationDrug, dose, route, time, what to do if a dose is missed, whether it can be hidden in food
LitterType, depth, scoop schedule, where bags go, clump count to expect
Medical historyDiagnoses, last vet visit, vaccine dates, allergies, weight on the day you leave
ConsentYour vet, clinic phone, after-hours number, a written spending cap
ContactsYou, a local backup who can decide, building access, alarm code
QuirksHiding spots, door-dashing, water bowl preference, the tap the cat drinks from

On the authorization: a clinic will not treat a cat without the owner's consent or a written agent. Leave a signed note naming the sitter, a stated limit, and a payment method. Without it, a sitter holding a vomiting cat at 9 pm has to choose between waiting and paying out of pocket.

Vaccines before boarding

Most facilities require FVRCP and rabies current, with rabies given at least 14 days before check-in so immunity has time to develop; some ask for feline leukemia (FeLV) for cats under 1 year or in group housing. Kennel cough is a dog requirement and is not standard for cats. Ask for the facility's list in writing 2-3 weeks ahead. A vaccine given the day before boarding does not protect your cat and may leave it mildly unwell for the first 48 hours of its stay.

Camera and daily proof

A camera pointed at the food bowl and litter area answers the two questions that keep owners awake: is the cat eating, and is the cat moving. Check at the same time each day, and pair it with a real visit — a camera cannot refill water or unjam a feeder.

Coming home

Expect 2-3 days of clinginess or pointed ignoring. Weigh the cat on day 1 and day 4; a loss of more than 5% of body weight, or no eating within 24 hours of your return, means a vet visit rather than another day of waiting.

If the cat was boarded, watch for sneezing, eye discharge, and a drop in appetite for 7-10 days, the usual incubation window for respiratory infections. Most cases are mild, but a cat that stops eating while sneezing needs to be seen.

Five steps that prevent most of this: book 3-4 weeks ahead; write the handover sheet and tape it up; sign the vet authorization with a spending limit; test the feeder and set out two water sources; record a baseline weight the morning you leave.

Frequently asked

Is 3 days too long to leave a cat alone with just one visit a day?

For a healthy adult cat between 1 and 12 years old, one 30-45 minute visit a day for 3 days is generally acceptable, because cats sleep 12-16 hours a day and do not need company the way dogs do. The visit is for food, water, litter, and a visual check, not entertainment. Add a second visit if the cat is very young, elderly, on medication, or eats wet food.

Does boarding always cause more stress than a sitter?

No. A cat that already travels well and tolerates strangers often settles into a quiet boarding unit faster than it accepts a stranger walking through its territory twice a day. Boarding becomes the better choice when the alternative is a sitter who cannot manage medication, or when you have no one reliable nearby. The deciding factor is the individual cat, not the category.

How soon before boarding does the rabies vaccine need to be given?

At least 14 days before check-in, because immunity takes roughly that long to develop after vaccination. A vaccine given the day before arrival satisfies paperwork but provides little protection and may leave the cat mildly unwell during its first two days in an unfamiliar place. Check the facility's exact list 2-3 weeks ahead rather than the week of travel.
