The first time I moved a cat any real distance, I did almost everything wrong. Cheap carrier from a supermarket. No practice runs. Fed her a full breakfast an hour before we left, which I regretted somewhere around junction 14. She screamed for ninety minutes, then went silent, which was somehow worse.
She was fine. I was not fine.
Since then I’ve done it properly a few times, and helped friends do it across borders, and the thing I keep coming back to is this: travelling with a cat is about 80% preparation and 20% actual travel. Get the carrier right and start early enough, and the journey itself is usually dull. Which is the goal. Dull is the goal.
This guide covers how to travel with a cat by plane, train and car, plus the ferry bit, the paperwork bit, and the honest conversation about when you should just leave her at home with a sitter. All costs are in pounds, euros and dollars, because border rules and airline fees don’t care where you live.

How to Travel with a Cat: Quick Facts
Quick Facts
Cabin, not cargo, wherever possible. Most airlines allow one small cat in the cabin if the cat plus carrier stays under the limit, typically 8kg in Europe and around 20lb in the US.
Typical in-cabin fee: around £75 to £160 each way (€87 to €185 / $100 to $200), paid per flight segment, not per trip.
Start the paperwork early. Microchip first, rabies jab second, everything else after. Cross-border trips usually need six weeks minimum, and there's a mandatory wait after the rabies vaccination.
Trains are the kindest option. UK rail lets you carry up to two pets free. Amtrak charges roughly $29 for cats under 20lb on journeys up to seven hours.
Pet cats cannot use Eurostar through the Channel Tunnel. Only registered assistance animals. If you're crossing between the UK and France, it's LeShuttle in your own car or a ferry.
Sedation is not the default answer. Vets are far more likely to suggest gabapentin or a mild anti-anxiety option than a proper sedative, and heavy sedation is a bad idea in the hold.
Best single investment: a good hard-based carrier your cat already likes, bought two months before you need it.
Tinker's Tip: Leave the carrier out in the living room permanently, door open, with a blanket inside. Not a week before the trip. Permanently. A carrier that only ever appears before something horrible happens becomes a horror object, and cats have long memories about this sort of thing.
Be Honest About Which Cats Should Travel At All
Not every cat should be on a plane. I say that as someone who loves the idea of the adventure cat in a backpack, watching the world go by with a slightly bored expression.
Most cats aren’t that cat. Most cats are deeply territorial creatures who measure their happiness in familiar smells, and a new flat with new carpet is genuinely stressful for them in a way it isn’t for a dog. A dog wants to be where you are. A cat wants to be where the cat’s things are, and would prefer you were also there, ideally.
So before anything else, work out which category your trip falls into.
- Relocation. You’re moving. The cat is coming. This isn’t optional and the whole guide applies.
- Long stay, one destination. A month or more in one place, with a stable base. Usually worth it.
- Holiday, multiple stops. Two weeks, three hotels, lots of moving about. Almost always better to leave her at home.
- Short break. A long weekend somewhere. Get a sitter. Seriously.
The rough rule I use: if the cat will spend more time in transit or adjusting than she will actually settled, don’t take her. A house sitter or a cattery costs less than the flights and causes a fraction of the stress. Cats are also famously fine at home alone with a competent visitor twice a day, which is not something you can say about a labrador.
Age and health matter too. Elderly cats, cats with kidney issues, flat-faced breeds like Persians who already struggle a bit with breathing, and very young kittens all sit at the higher-risk end. Ask your vet before you book anything, not after.
Reality check: Taking your cat on holiday is mostly for you, not for her. That's allowed. Just know which one it is, because it changes how much stress you should be willing to put her through.
The Carrier Is The Entire Trip
Get this bit right and everything downstream gets easier. Get it wrong and you’ll spend a flight listening to a cat trying to dismantle a zip from the inside.
What you want is a carrier with a rigid base and soft, ventilated sides, big enough for her to stand up, turn around and lie flat without touching the walls. Top-opening matters more than people realise, because lowering a cat in from above is dramatically easier than posting a reluctant animal through a front door sideways. Anyone who has tried the sideways method knows exactly what I mean.
Size is dictated by the strictest leg of your journey. Airlines vary, but soft carriers roughly 45cm long are the safe middle ground for cabin travel. Amtrak caps carriers at 19 by 14 by 10.5 inches. Continental European trains want small pets in a carrier no bigger than about 45 by 30 by 25cm. Buy for the tightest limit and you’re covered everywhere.

| Mode of travel | Typical carrier limit | Weight limit (cat + carrier) | Hard or soft sided |
|---|---|---|---|
| Plane, in cabin (Europe) | Around 45 x 30 x 25cm, must fit under the seat | 8kg is the common European standard | Soft, almost always |
| Plane, in cabin (US carriers) | Roughly 18 x 11 x 11 inches, varies by aircraft | 20lb on some, no stated limit on others | Soft preferred, some allow hard |
| Plane, hold or cargo | IATA-compliant crate, sized to the cat | No practical limit | Hard only, bolted not clipped |
| Train (UK and Europe) | About 45 x 30 x 25cm on continental services | Under 6kg travels free on many routes | Either |
| Train (Amtrak) | 19 x 14 x 10.5 inches | 20lb combined | Either, must be leak proof |
| Car | Whatever fits the seat properly | None | Hard sided is safer in a crash |
Then comes the training bit, which is boring and completely non-negotiable. Feed her in it. Put treats in it. Take her on ten-minute drives that end back at home rather than at the vet. Do this for weeks, not days. A cat who has learned the carrier means "car, then home again" behaves very differently from one who has learned it means "car, then thermometer".
Tinker's Tip: Zip ties on the carrier zips, threaded loosely so security can cut them. Cats are much better at zips than the packaging suggests, and a cat loose in an airport is the single worst outcome on this entire list.
Paperwork: Start Sooner Than You Think You Need To
Domestic trips are simple. Most airlines want a health certificate from a vet issued within ten days of travel, some want proof of rabies vaccination, and a few want nothing at all. Check when you book, not the week before.
International is where people come unstuck, and it’s almost always a timing problem rather than a document problem. The order is fixed and you cannot fudge it.
- Microchip first. If the chip goes in after the rabies jab, the jab doesn’t count and you start again. This catches out more people than anything else.
- Rabies vaccination second. Then a mandatory wait, commonly 21 days, before travel.
- Health certificate or animal health certificate third. Issued close to departure, valid for a limited window.
- Destination-specific extras. Blood titre tests for some countries, import permits for others, and quarantine in a handful.
One small mercy for cat people: cats don’t need the tapeworm treatment that dogs do when entering certain countries. Slightly less faff, slightly cheaper vet bill.
If you’re travelling out of the UK specifically, our full guide to taking your pet abroad from the UK walks through the animal health certificate process, costs and approved routes in proper detail. Budget somewhere around £150 to £350 per pet (€175 to €405 / $200 to $470) for a single trip once you add up the vet visits.
Small print: Photograph every document and every microchip number, and check the number on the paperwork actually matches the number the vet scans. A single transposed digit at a border turns a holiday into a very expensive afternoon.
Planes: Cabin If You Possibly Can
The rule is simple. Cabin good, hold bad. If your cat plus carrier fits the limit, pay the fee and keep her under the seat in front of you where you can put a hand on the carrier.
You almost always have to book the pet by phone after you’ve booked yourself, because most airlines cap the number of animals per cabin and don’t handle it online. Space goes quickly on popular routes. I’d do it the same day you book the flight.
Fees are charged per segment, which is the detail that stings. A connection means paying twice each way.

| Airline group | In-cabin fee, each way | Approx GBP / EUR | Worth knowing |
|---|---|---|---|
| Delta, United, American | $150 domestic, $200 international | £120 to £160 / €140 to €185 | Civilian cargo programmes largely closed, so cabin or nothing |
| Alaska, Southwest, Frontier | $95 to $100 | £75 to £80 / €88 to €92 | Cheapest mainstream US option, domestic focus |
| JetBlue | $125 | £100 / €115 | One of the more generous weight allowances |
| Air France, KLM | €70 to €200 depending on route | £60 to £175 / $75 to $215 | Short European hops are at the cheap end |
| Lufthansa, SWISS, Austrian | Roughly €55 to €190 | £48 to £165 / $60 to $205 | 8kg combined limit, weighed at the desk |
| Cargo or manifest freight | $300 to $2,000+ | £240 to £1,600 / €280 to €1,850 | Priced on crate size and route, not your ticket |
Two things people find out the hard way. First, some destinations override the airline entirely. Inbound routes to the UK, for example, don't allow cats in the cabin at all, no matter how small she is or what the airline's website says, so a cat coming into Britain by air travels as freight. Second, that 8kg European limit is combined weight, and it's checked. A 6kg cat in a 2.5kg carrier fails.
Long haul with a cat in the cabin is doable but it's a commitment. She doesn't come out. She uses an absorbent pad in the carrier, she has water at your seat, and you accept that she may not eat until you land. Feed a small meal about four hours before departure, not right before.
Watch out: At security you'll be asked to take the cat out of the carrier and carry her through the scanner. Put a harness and lead on her before you get to the queue and hold the lead. This is the moment cats escape, and airport terminals are enormous.
Sedation, Calming, And What Your Vet Will Actually Say
Everyone asks about this, usually hoping the answer is “yes, knock her out”. It isn’t, generally.
Proper sedation drops blood pressure and interferes with temperature regulation and balance, which is precisely what you don’t want in a pressurised hold where nobody can check on her. It also has a nasty failure mode: some sedated animals are still aware and frightened but can’t move or respond, and that tends to make the next journey worse rather than better.
What vets more commonly prescribe is anti-anxiety medication rather than sedation. Gabapentin comes up most often, usually given somewhere between forty-five minutes and a couple of hours before travel. Trazodone and pregabalin get used too. All of them are dose-dependent and prescription-only, and a trial run at home a fortnight beforehand is standard advice, because a small minority of cats react badly and you’d much rather find that out on your sofa.
The non-drug options are worth doing regardless:
- Pheromone spray in the carrier fifteen minutes before you set off, not while she’s inside it.
- A blanket over the carrier on three sides. Darkness helps most cats a lot.
- Something that smells of home, ideally an unwashed t-shirt of yours. It works better than a new toy.
- Your own calm. Cats read tension off you very efficiently, and a stressed owner cooing anxiously through the mesh is not the reassurance you think it is.
Fact: Calming effects from gabapentin typically last six to twelve hours, and longer in older cats or ones with reduced kidney function. Time the dose to the journey, not to when you leave the house.

If the route exists, take the train. No pressure changes, no separation, no hold, no queue at security where you have to unpack your cat. You sit down, the carrier goes on the seat beside you or at your feet, and the cat sulks in the dark for three hours. Perfect.
Rules vary by operator, and one of them will catch you out if you're crossing the Channel.
← Swipe to scroll on mobile
| Operator | Cats allowed? | Cost | Conditions |
|---|---|---|---|
| UK National Rail | Yes | Free | Up to two pets per passenger, in a carrier |
| Eurostar to or from London | No | Not applicable | Registered assistance animals only, no exceptions |
| Eurostar continental routes | Yes | Free under 6kg | Carrier max 45 x 30 x 25cm, on your lap or at your feet |
| SNCF (TGV, TER, Intercités) | Yes | From €10 (£9 / $11) per train | Fixed pet fare, carrier required |
| Amtrak | Yes | Around $29 (£23 / €27) | Under 20lb combined, journeys up to 7 hours, coach only |
| Coaches (FlixBus, National Express) | No | Not applicable | Assistance animals only on most networks |
The Eurostar situation trips people up constantly, so it's worth being blunt about it. You cannot take a pet cat through the Channel Tunnel on a passenger train. That restriction comes from the tunnel concession rather than the train company, so new operators appearing on the route won't change it. Your options between Britain and France are LeShuttle with your cat in your own car, a ferry, or a specialist pet taxi that drives you both through.
Amtrak's seven-hour cap is per journey, and pets aren't allowed in sleeper accommodation on most services, so a coast-to-coast trip with a cat isn't really a train trip. Reservations are limited per train too, and they do sell out.
Timing tip: Book off-peak. A half-empty carriage is a completely different experience for a cat than a rush-hour service where somebody's suitcase is pressed against the mesh for an hour.
Automobiles: The One You'll Probably Actually Do
Most cat travel is car travel. Vet trips, house moves, the long drive to a holiday cottage. And most people do it slightly wrong, myself included for years.
The carrier goes on the back seat, secured with the seatbelt through the handle or strap. Not in the boot, not on the passenger seat where an airbag could deploy into it, and absolutely not loose in the car. A cat under the brake pedal on a motorway is a genuinely terrifying scenario, and it happens.
Some practical bits that make the difference on longer drives:
- Keep the car cool. Cats overheat faster than you’d expect, and a carrier in direct sun through a window gets warm quickly.
- Break every three to four hours, but do the break with the doors shut and the windows up. Offer water, check her, don’t open the carrier in a service station car park.
- Never leave her in a parked car. Not for five minutes, not with the window cracked.
- Litter tray stops only if you’re stopping somewhere enclosed, like a hotel room. Most cats will simply hold on, and an absorbent pad in the carrier handles accidents.
If you’re hiring a vehicle for a move or a long trip, check the rental company’s pet policy before you book. Some charge a cleaning fee if they find fur, and a few forbid animals outright. Comparing car hire across suppliers usually turns up at least one that’s relaxed about it, and it’s cheaper to know upfront than to argue at the return desk.
For the airport leg specifically, I’d rather pre-book a private airport transfer than gamble on a taxi rank. Plenty of drivers will refuse a carrier without warning, and standing outside arrivals at midnight with a distressed cat while three cabs drive off is a memory I’d rather not repeat.
Quick win: Put a puppy training pad in the base of the carrier under the blanket. It costs pennies, it absorbs the worst of any accident, and it means you can swap the top layer at a service station without a full clean-up operation.
Ferries And Crossings: Slower, Calmer, Often Better
Ferries are underrated for cats, particularly on the routes between Britain and mainland Europe where the tunnel is closed to pets on trains.
Broadly there are three setups. Your cat stays in the vehicle on the car deck for the whole crossing, which is common on short routes and is fine for a ninety-minute hop but not for an overnight sailing. Or she stays in a pet-friendly cabin with you, which several operators now offer and which is worth every penny on a long crossing. Or on some ships there are kennels, which for a cat I’d avoid unless there’s no alternative.
LeShuttle through the tunnel is the fastest crossing between Folkestone and Calais and your cat never leaves the car. The pet supplement runs around £22 each way (€27 / $28) per animal, with up to five pets per vehicle. Thirty-five minutes and you’re in France.
Whatever route you pick, bring the paperwork to the check-in desk in a folder, not buried in a bag. Pet checks at ferry ports and tunnel terminals are done properly, and the queue behind you is real.
Check this first: Pet cabins on overnight ferries are limited and they go early, especially in summer. Book the cabin at the same time as the crossing, not afterwards.

What To Actually Pack For A Cat
Less than you think, but the right things. I’ve overpacked for cats more than once and ended up carrying a bag of untouched toys around Europe.
- Her food, in her brand. Switching food and switching country in the same week is asking for an upset stomach. Bring enough for the trip plus three days.
- A collapsible litter tray and a small bag of her usual litter. The smell of familiar litter matters more than the tray does.
- Harness and lead, fitted and tested at home. Non-negotiable for airports.
- Absorbent pads, several. Cheap, light, saves everything.
- A blanket that already smells of home. Don’t wash it before you go. That’s the entire point of it.
- Documents in a folder, plus photos of everything on your phone.
- A recent photo of her that clearly shows her markings, in case she gets out.
- Any medication, in original packaging with the label intact.
Skip the toys. A cat in an unfamiliar room is not going to play with a feather wand on day one, and by day three she’ll be playing with the hotel curtain tie anyway. Our travel essentials checklist covers the human half of the packing, and the family packing list is useful if you’re doing all of this with children in tow as well, which I do not envy you.
Money saver: Buy litter at the destination rather than hauling it. Bring a small zip bag of the used stuff from her tray at home instead, and mix it into the new litter. It smells right to her, and it weighs nothing.
Arriving: Give Her One Room, Not The Whole Place
This is the part that gets skipped, and it’s the part that determines how the first week goes.
Do not open the carrier in the middle of a big unfamiliar space. Pick one small room, ideally a bathroom or a bedroom, and set it up before she comes out. Litter tray in one corner, food and water in another, her blanket somewhere she can hide. Then open the carrier door and leave it open, sit down, and let her come out in her own time. Some cats stroll out in ten minutes. Some sit under the bed for a day and a half. Both are normal.
After twenty-four hours or so, open the door to the rest of the space and let her expand into it. Trying to speed this up doesn’t work and usually just means a cat wedged behind a wardrobe you can’t move.
On accommodation: “pet friendly” covers a lot of ground and some places mean dogs only. Filter properly and read the small print before booking, because a lot of listings apply a per-night pet fee that isn’t shown in the headline price. When I’m searching stays I check the pet policy on the property page rather than trusting the filter, and I’ve had good luck finding cat-tolerant apartments on Booking.com where hosts state the rules plainly. Apartments generally beat hotels for cats anyway. Kitchen, door you can shut, no housekeeping wandering in and leaving a door open.
One more thing worth sorting before you go: vet care abroad is expensive and there’s no equivalent of the NHS for cats. A weekend emergency in rural France can run into four figures very quickly. Some travel insurance policies add pet cover for a modest extra premium, covering vet bills abroad and sometimes quarantine costs if your return paperwork goes wrong. For a long trip it’s an easy yes.
Must do: Update the microchip registration with your new address and phone number before you travel, not after you arrive. A found cat with an out-of-date chip is a found cat nobody can return to you.
What It All Costs, And What The Alternative Costs
Worth doing this sum honestly before you commit, because for a two-week holiday the numbers often argue for a sitter.
← Swipe to scroll on mobile
| Item | GBP | EUR | USD |
|---|---|---|---|
| Decent airline-approved carrier | £35 to £80 | €40 to €93 | $45 to $100 |
| Microchip and rabies vaccination | £45 to £90 | €52 to €105 | $57 to $115 |
| Health certificate or AHC | £90 to £200 | €105 to €232 | $115 to $255 |
| Return flight fees, cabin, one connection | £240 to £480 | €280 to €555 | $300 to $600 |
| Pet supplement, LeShuttle return | £44 | €54 | $56 |
| Cattery, per night | £12 to £25 | €14 to €29 | $15 to $32 |
| Home visits by a sitter, per day | £12 to £20 | €14 to €23 | $15 to $25 |
Two weeks of home visits comes to less than the flight fees alone, and the cat stays in her own house with her own smells. That's not an argument against travelling with cats. It's an argument against travelling with cats for short holidays, which is a different thing.
Good to know: Book the sitter or cattery earlier than you'd think. Good ones are booked solid over school holidays and Christmas, and the ones with availability in December are usually available for a reason.
Go And Leave The Carrier Out
Everything else in this guide is logistics. Fees, forms, seat limits, carrier dimensions. All of it solvable with a phone call and a bit of lead time.
The part that decides how the journey actually goes is the boring bit nobody does: the carrier sitting open in your living room for weeks beforehand, with a blanket in it and the occasional treat, until it stops being a threat and starts being furniture. Do that and you’re most of the way there.
And be honest with yourself about the trip. If she’s moving house with you, she’s coming, and this guide is your checklist. If it’s a fortnight in Spain, she’d genuinely rather stay home and judge a house sitter.
For more on travelling as a household, the family and senior travel hub has the rest of our guides, and the pet travel guide goes deeper on paperwork and approved routes. When you’re ready to book the stay, filter properly for pets on Booking.com and message the host before you pay, because a two-line reply about the pet policy is worth more than any filter.

FAQs
Travel Hubs
Can cats fly in the cabin with you?
Yes, on most airlines, provided the cat and carrier together stay under the limit and the carrier fits under the seat in front. European carriers commonly cap this at 8kg combined, while several US airlines use 20lb or simply require the carrier to fit. You normally have to add the cat by phone after booking your own seat, and spaces per flight are limited.
How long can a cat travel without a litter tray?
Most healthy adult cats manage eight to twelve hours without needing one, and many will refuse to use a tray while travelling anyway. Line the carrier with an absorbent pad, offer water at stops, and set the tray up properly as soon as you reach a room where she can be shut in safely.
Should I sedate my cat for a flight?
Usually not, and never without veterinary advice. Sedatives affect balance, blood pressure and temperature regulation, which is particularly risky in the hold. Vets more often prescribe a mild anti-anxiety medication such as gabapentin, and they’ll want you to trial the dose at home a couple of weeks before you travel.
Can I take my cat on the Eurostar?
Not on services to or from London, where only registered assistance animals are permitted. Pet cats are allowed on Eurostar’s continental routes between Belgium, France, Germany and the Netherlands, travelling free under 6kg in a carrier no larger than 45 by 30 by 25cm. To cross the Channel with a cat, use LeShuttle in your own vehicle or a ferry.
How far in advance should I start preparing?
Six weeks minimum for any cross-border trip, and longer if your cat isn’t already microchipped and vaccinated against rabies, because of the mandatory wait after the jab. For the cat’s sake, start carrier training two months out. That part costs nothing and makes the biggest difference on the day.
