Cats escaping during transport: what a study reveals about the real risk factors
Published by Planète Pets · managing editor: Clément Lacaille · how our guides are written
Bolting the moment the cat comes out of the carrier — at the clinic door, in the car park, through an open door — is one of the most feared scenarios of pet transport. A study published in 2021 by Tateo, Zappaterra, Covella and Padalino in the Italian Journal of Animal Science observed the behaviour of 95 cats during a veterinary examination to identify what actually raises this risk (see the study). Our other guidance on the topic is gathered in the cat travel and safety section.

Two cat profiles at higher risk
First finding: a cat's age shapes the type of reaction. Young cats show more anxious behaviour and are more prone to escape attempts, while older cats tend to display an irritated profile — scratching, tail lashing, raised fur — without necessarily trying to actively flee. Second finding, unsurprising but now actually measured: cats experiencing their very first consultation show a higher level of stress and fear than those already used to the clinic.
The real risk factor: no experience of the carrier and the car
The study's most actionable result concerns familiarity with transport itself: cats with little experience of car rides and carriers show significantly more vocalising, hissing, ears pinned back — and escape attempts. In other words, it isn't so much the consultation itself as the unfamiliarity of the journey that triggers the impulse to bolt at the slightest gap in an open door.
Reducing the risk before the trip, not just on arrival
This link between familiarity and calm echoes exactly the logic covered in our article on daily carrier training: a cat that associates the carrier with a neutral, everyday spot, rather than a rare and stressful event, approaches the journey far less on edge. In practical terms, this also means extra caution is warranted at the exact moment of opening the door — car doors locked, windows up, a safety harness as backup inside the carrier — for a young or unfamiliar cat, precisely the two profiles the study identified as most at risk of an escape attempt.
If the escape has already happened
Despite every precaution, a cat can slip free in a split second the moment a car door opens. In that case, the right immediate search reflexes matter far more than any prevention after the fact: our guide on what to do when a cat is lost details the steps to take in the first few hours, which are decisive for a stressed cat that usually stays hidden close to the escape point rather than wandering far.
The study's limits
This is an observational study carried out in veterinary practice, not a controlled trial isolating the single variable of "carrier" or "car": familiarity with transport is associated with fewer escape behaviours, but other factors (individual temperament, pain, reason for the visit) also play a role. These results point toward sensible prevention; they do not guarantee the total absence of risk.
Frequently asked questions
At what age does a cat become less prone to escape attempts?
The study sets no precise threshold: it shows a tendency among young cats, best weighed against each individual cat's experience rather than age alone.
Does a single vet visit habituate a cat to transport?
No: the study links familiarity to repeated, neutral exposure, not a single one-off outing. Find all our guides on the cat hub.
