If the trip is under 72 hours, leave the cat at home and pay someone to visit twice a day. Two visits cost $30–$60 a day against $100–$300 for boarding, and the cat stays in the only territory it knows. Take the cat along only when the trip runs 4 days or longer and you are either driving under 6 hours or flying with the cat in the cabin. Everything below is how to do either without a stress-related vet bill.

The 72-Hour Rule

Trip lengthBest optionTypical cost
1–2 nightsStay home, sitter once a day$15–$30 a visit
3 nightsStay home, sitter twice a day$60–$120 total
4–7 nightsSitter twice daily, or boarding$30–$60 a day, or $25–$60 a night
8+ nightsBoarding with a vet on call, or a live-in sitter$40–$80 a day
Any length, cat on daily medicationVet boarding, not a friend$45–$90 a day

A cat left alone for 48 hours with 3 days of food and 2 clean boxes will usually be fine physically and miserable socially; past 72 hours, the risks that matter are a blocked bladder, a knocked-over water bowl and a cat that stops eating because nobody is watching.

Leaving: What the Sitter Actually Needs

  • Food weighed into 7 daily portions, not a full bin — a 4.5 kg cat eats 55–70 g of dry food a day, and free-feeding for a week adds 300–500 g.
  • Two boxes for one cat, scooped daily, in separate rooms.
  • Three water bowls, one of them a fountain, refilled every visit.
  • A one-page sheet: vet name, 24-hour number, insurance policy number, microchip number, and the cat's weight.
  • Written permission to authorise treatment up to a stated amount, usually $300–$500.
  • Two 15-minute play sessions a day for a cat under 3; a bored cat opens cupboards.

Portion sizes come off the food packet and the food calculator, not off the scoop in the cupboard. Ask the sitter to send one photo a day with the food bowl in frame; it catches a cat that has stopped eating 3 days earlier than a phone call would.

Driving: The 6-Hour Rule

Under 6 hours of driving in a day, a cat travels better than most owners expect. Over 8 hours, split the drive or leave the cat home. The carrier should be 1.5 times the cat's length from nose to tail base, strapped in with the seat belt, and covered with a light towel on three sides. No food for 3–4 hours before departure, water every 2 hours on a stop, and the car kept at 20–24°C — a parked car at 30°C outside reaches 45–50°C inside in 30 minutes. Never let the cat out of the carrier in a moving car, and never travel with the cat loose in a van.

Flying: In the Cabin or Not at All

In-cabin is the only option worth planning for. Expect $100–$150 each way, a soft carrier no larger than 18 × 11 × 11 inches (45 × 28 × 28 cm), and a 7–8 kg combined weight limit on most carriers; book the pet slot when you book the ticket, because 2–4 per flight is the usual cap. Cargo costs $200–$400 and is not offered by every airline in every season; a brachycephalic cat should not fly cargo at all. Sedation is a decision for your vet, usually given 90–120 minutes before departure, and never a dose you pick yourself — a sedated cat cannot regulate its own temperature in a hold or a cabin.

Boarding: Book Early or Stay Home

Book 14–21 days ahead for an ordinary trip and 30–45 days ahead for a holiday week; the good catteries in any city fill by early December for the last week of the month. Ask four questions: how many cats per pen (2–4 is normal, 10 is not), whether vaccination proof is required for FVRCP and rabies (it should be), who is on call at 2 a.m. (a vet, or nobody), and whether you can see the pen before paying. Rates run $25–$60 a night, with a 1–2 night minimum and a surcharge of $10–$20 a night for medication.

The 72-Hour Stress Plan

Cats do not generalise well, so the work happens before and after, not during.

  • 72 hours before: put the carrier out with a worn T-shirt inside and feed one meal next to it.
  • 24 hours before: spray the carrier with pheromone 15 minutes before the cat goes in, never on the cat.
  • Day of: no food 3–4 hours before a flight, 2–3 hours before a short drive.
  • Arrival: one room, door closed, box and water, 24 hours with no visitors.
  • 72 hours after: no new food, no grooming appointment, no guests; watch appetite, litter use and hiding.

Closed windows, dry cabin air and a strange flat are the classic setup for an upper respiratory flare 3–5 days after travel; the signs are in dry air and respiratory signs, and cold-weather handling at both ends in winter heating and cold.

When to Cancel the Trip Instead

Do not travel with a cat that has had a urinary blockage in the last 30 days, is on daily medication that needs refrigeration, has a heart murmur not yet worked up, or is over 14 and has never travelled. Do not leave a cat alone if it has been to the vet in the last 5 days. And call a vet instead of boarding if the cat has not eaten for 24 hours, is straining in the box, or is breathing with its mouth open — that last one is an emergency at any hour, holiday or not.

Five Things to Do This Week

  1. Decide by the 72-hour rule: under 3 days, book a sitter, not a carrier.
  2. Weigh out 7 daily portions and write the amounts on the sheet.
  3. Check carrier size against the cat's length, and the airline's weight cap.
  4. Book boarding 21 days out, or 45 if it is a holiday week.
  5. Photograph the cat, the microchip number and the insurance card into one album.

This article is educational and does not replace veterinary diagnosis. A cat that has not urinated in 24 hours, or is open-mouth breathing, needs a vet immediately.

Frequently asked

Can I leave my cat alone for 3 days?

Not alone, but at home with visits. Two sitter visits a day at $15–$30 each covers 3 days for $60–$120, which is cheaper than boarding at $25–$60 a night. Leave 3 days of food, 2 clean boxes and 3 water bowls, and have the sitter send a photo daily. Past 72 hours, a blocked bladder or a cat that stops eating needs someone checking.

How do I fly with a cat in the cabin?

Book the pet slot with your ticket, since most flights cap at 2–4 pets. Expect $100–$150 each way, a soft carrier within 45 × 28 × 28 cm, and a 7–8 kg combined limit. Stop food 3–4 hours before departure. Sedation is your vet's call, usually given 90–120 minutes before the flight, and never self-dosed.

How far ahead should I book a cattery for the holidays?

Fourteen to 21 days ahead for an ordinary trip, and 30–45 days for a holiday week — the last week of December is usually full by early December. Rates are $25–$60 a night with a 1–2 night minimum, plus $10–$20 a night for medication. Ask how many cats share a pen and who is on call overnight before paying.
