Seven differences. The fourth explains why taking a cat along is often a bad idea, and you have to be able to admit it.

Almost every piece of advice on travelling with an animal is written for the dog. The cat works differently on seven points, and two of them should make you give up the idea.
This is the difference everything else rests on. A dog follows its owner and the place matters little; a cat loses its bearings as soon as its territory changes, and the owner's presence does not make up for it.
That does not mean a cat is not attached to its humans — it means that moving a cat costs it something that moving a dog does not.
The opposite of the human instinct. A cat loose in a car looks for somewhere to hide, slips under the pedals, and wears itself out. A carrier the right size for it, covered with a cloth, produces a silent cat within minutes.
It is also the only safe arrangement: a cat moving about inside a vehicle in motion is a danger to itself and to the driver.
Some of the vocalising is a bid for contact, not a call for help. Answering it by taking the cat out of the carrier reinforces the behaviour and removes the safety.
Speaking calmly, without opening the carrier, gives the contact without the trade-off. A cat that falls silent after twenty minutes has adapted, not given up.
For a week away, a cat is generally better off at home with daily visits than moved to a place it does not know. It is the opposite of what you would do for a dog.
You have to be able to admit it, because the opposite decision is nearly always made for the owner's convenience. Exceptions exist — a cat used to travelling, a long stay, a very bonded cat — but they are exceptions.
A cat in a new environment cuts down or stops eating for twenty-four to forty-eight hours. It is an adjustment reaction, not a problem with the food.
Beyond forty-eight hours, though, it becomes a reason to see a vet: prolonged fasting in a cat puts it at risk of liver damage, and that risk is real.
This is the firmest rule in this guide. A cat let loose in unfamiliar territory does not know how to come back: it does not run away, it gets lost.
Cats lost on holiday are nearly always lost this way, often on the second or third day, when the owner decides the animal “has settled in”.
A cat in a harness does not walk like a dog: it explores in bursts, freezes, and can twist out of a badly fitted harness. The outing lasts a few minutes, in an enclosed space.
Getting a cat used to a harness takes weeks at home before the first use outdoors. Starting on the day you leave produces nothing but a panicked cat on the end of a line.
