A pet carrier for dogs or cats is a soft, ventilated and secure piece of luggage designed to let your pet travel comfortably on a plane (cabin), train or car, while meeting transport‑provider requirements.
Choosing the right model depends on three key criteria: the dimensions (your pet must be able to stand up, turn around and lie down comfortably), the airline compliance (generally a maximum of 45 × 30 × 25 cm and 8 kg pet + carrier) and the lightweight construction to maximise the remaining weight allowance for your pet.
What are the essential criteria for choosing a pet carrier?
Before comparing prices or colours, five non‑negotiable criteria determine the quality of a pet carrier: the size adapted to your pet’s body shape, multi‑side ventilation, an interior safety leash, a removable washable base, and a lightweight construction. A carrier that meets all five ensures your pet’s comfort — and your peace of mind.
1. Size: how to measure your pet to choose the right carrier
Your pet must be able to stand up, turn around and lie down comfortably. To measure correctly:
- Length: from the neck to the base of the tail + 5 to 8 cm
- Height: from the floor to the top of the head when standing + 5 cm
A space that is too tight increases stress; too large, and the animal feels less secure.
Concrete example: a 4 kg cat is usually between 35 and 45 cm long. A carrier measuring 45 × 28 × 23 cm with a 31‑litre volume — like the Lipault City Plume Pet Carrier — offers comfortable space without being oversized.
2. Ventilation: why mesh panels are essential
Mesh openings regulate the internal temperature and allow the animal to see its surroundings, which significantly reduces anxiety during transport. According to veterinary recommendations, a pet carrier should have at least 2 to 3 mesh panels on different sides to ensure proper airflow, even during long waits in airport terminals.
3. The interior leash: the small detail that prevents accidents
A short strap attached inside the carrier prevents the animal from jumping out as soon as the zipper opens. It’s an essential safety feature in stressful environments such as airports, train platforms or metro halls. The best models include a swivel snap hook to avoid tangling.
4. The removable, washable base
A removable, washable cushion at the bottom of the carrier makes travel more comfortable and simplifies cleaning. It absorbs small accidents and can be removed in seconds. Choose a memory‑foam cushion with a machine‑washable cover.
5. Carrier weight: an often underestimated criterion
If your cat weighs 4 kg and the carrier weighs 3 kg, you’re already carrying 7 kg before adding anything else — dangerously close to the 8 kg limit imposed by most airlines.
A lightweight carrier (between 1 and 1.5 kg empty) makes all the difference.
Materials like twill nylon — used in Lipault’s pet carriers — offer an excellent strength‑to‑weight ratio at only 1.3 kg empty, leaving up to 6.7 kg of margin for the animal.
What are the airline standards for transporting a pet in the cabin?
This is the question most pet owners ask themselves too late. Here are the rules you need to know to travel in the cabin with your pet:
| Company | Max. bag dimensions | Max. weight (pet + bag) | Estimated price |
|---|---|---|---|
| Air France | 46 × 28 × 24 cm | 8 kg | 40–200 € depending on route |
| Vueling | 45 × 39 × 21 cm | 8 kg | ~40 € |
| Ryanair | 40 × 25 × 20 cm | 8 kg | Not accepted in cabin |
| SNCF / Eurail (train) | 45 × 30 × 25 cm | No strict limit | ~10 € |
*Requirements may vary depending on the route. Always check your carrier's pet travel policy before your journey.
As a general rule, pets travelling in the cabin must not exceed a total of 8 kg, including the carrier. The bag must fit fully under the seat in front of you for the entire flight, including take‑off and landing. If your pet exceeds 8 kg, it must travel in the hold in an IATA‑approved rigid crate.
The Lipault City Plume Pet Carrier for dogs and cats measures 45 × 28 × 23 cm and weighs just 1.3 kg when empty — specifically designed to fit under an aircraft seat.
Comparison: the best pet carriers for dogs and cats in 2026
To help you choose the best pet carrier, here is a comparison based on the criteria that truly matter: airline compliance, empty weight, volume, ventilation, and overall value for money.

Why choose it: it’s the lightest model in our comparison (1.3 kg), giving you 6.7 kg of margin before reaching the 8 kg cabin limit. Its 31‑litre volume is the most generous, and the water‑repellent twill nylon offers weather protection without unnecessary rigidity. As one user puts it: “As functional as it is elegant — lightweight, it makes every type of transport easier while keeping the pet very comfortable.”
Lipault Lost In Berlin Pet Carrier for dogs and cats
Same functional and ergonomic design — with the distinctive character of the Lost In Berlin range: a matte rubber‑effect polyurethane/polyester material that is scratch‑resistant and waterproof. Ideal if you're looking for a pet carrier that matches a coordinated luggage set.
Why choose it: for those who want a premium look and a material that’s even more weather‑resistant, while keeping the same performance as the City Plume.
What both Lipault models have in common
Both carriers feature a rear trolley sleeve that allows you to slide the bag over a suitcase’s telescopic handle — a real advantage when juggling luggage, passports and boarding passes in a crowded terminal. They are also compatible with the Lipault Travel Accessories Cleaner for easy, long‑lasting maintenance.
How to get your pet used to the carrier before travelling
Even the best carrier won’t help if your pet has never set a paw inside it before the big day. Gradual familiarisation is essential, and veterinarians recommend starting at least two weeks before departure.
Leave the carrier open in your living room. Place inside a piece of clothing with your scent or your pet’s favourite toy. Let them explore freely with no pressure.
Encourage your pet to enter using treats. Do not close the carrier. Reward every voluntary entry.
Close the carrier briefly for a few seconds, then a few minutes. Start at home, then try a short outing (around the block).
Take a short car ride or use public transport with the carrier closed so your pet becomes familiar with movement and noise.
Most cats and small dogs adapt within one to two weeks. Pets that still show signs of panic at this stage should be seen by a veterinarian before any air travel.
How to care for a pet carrier
Twill nylon is easy to clean with a damp cloth or a suitable product such as the Lipault Travel Accessories Cleaner. Avoid machine‑washing, as it may damage the water‑repellent finish. The inner cushion can be removed and washed separately.
Expert tip: after each use, leave the carrier open and laid flat for 24 hours instead of storing it closed — especially if your pet has been warm or sweaty. This prevents odours and helps preserve the fabric over time.
FAQ — Pet carrier for dogs and cats
Which carrier should I choose to travel with my pet?
For air, train or car travel, choose a soft carrier under 45 × 36 × 25 cm, weighing less than 1.5 kg empty, with at least two mesh ventilation panels, an interior safety leash, and a removable washable cushion.
Can my cat or dog travel in the cabin on all flights?
No. Policies vary by airline and destination. Some carriers do not allow pets in the cabin on long‑haul routes. Cabin pet spots are limited (often 1 to 3 per flight). Always book your pet’s place at the same time as your ticket and check the latest rules on the airline’s official website.
What size carrier for a 4 kg cat?
A 4 kg cat is usually 35–45 cm long. A 45 × 28 × 23 cm carrier with a 31‑litre volume provides enough space for them to lie down comfortably. Measure your cat’s back length (from neck to base of tail) and add 5–8 cm — that’s the key criterion.
What’s the difference between a soft carrier and a rigid crate?
A soft carrier (like Lipault models) is designed for cabin travel: lightweight, flexible and able to fit under the seat. A rigid IATA‑approved crate is required for hold transport for pets over 8 kg (pet + container). They serve different purposes.
Are Lipault carriers suitable for small dogs?
Yes. The range is designed for small pets — cats, small dogs (chihuahua, yorkshire, bichon, cavalier king charles, etc.) and similar animals up to around 6–7 kg. Always check the maximum weight and dimensions based on your pet’s size. The 2‑year worldwide limited warranty allows you to purchase with confidence.
How do I travel by train with my pet?
Train policies vary across Europe. Most major rail operators accept pets in carriers that fit under the seat and remain closed throughout the journey. Larger dogs may need to travel on a lead and wear a muzzle depending on the country. Always check the rules of the specific rail operator before travelling.
