How to Choose a Pet Carrier: What to Look for Before You Travel

A pet carrier is one of those purchases most owners don't think about until they need one urgently — usually the night before a vet appointment or a trip. Buying in a hurry means you often get the wrong size or the wrong type.

This guide breaks down what actually matters so you can choose once and choose well.

Hard-Sided vs. Soft-Sided: Which Is Right for You?

Hard-sided carriers are more durable, easier to clean, and provide better protection in a car accident. Most cats feel more secure in a hard-sided carrier because the enclosed sides reduce visual stimulation. They're also better for airline cargo holds.

Soft-sided carriers are lighter, more flexible (some fit under airline seats), and easier to store. They're generally better for calm, well-travelled pets and for short trips. Not suitable for anxious pets that scratch or push against the sides.

For most cat owners: hard-sided. For most dog owners travelling by car or train: soft-sided is usually fine for calm dogs.

Size: The Most Common Mistake

The carrier should be large enough for your pet to stand, turn around, and lie down comfortably — but no larger. A carrier that's too big doesn't feel like a safe den; it feels like an open space, which increases anxiety.

How to measure:

• Length: nose to base of tail + 10 cm
• Height: floor to top of head when standing + 10 cm
• Width: widest point of shoulders + 5 cm

Weigh your pet too — airline carriers have weight limits (usually 6–8 kg including the carrier).

Features Worth Paying For

Top-loading opening — invaluable for cats. A cat that won't enter from the front will often accept being lowered in from the top. Many vets prefer top-loaders because they can examine a cat without fully removing it from the carrier.

Removable top — if you need to leave the carrier base at the vet for the cat to sit in, a two-part design makes this easy.

Secure latches — test them before you need them. Carriers with cheap plastic clips can pop open if the pet pushes hard enough.

Ventilation on multiple sides — important for warm weather and for cats that overheat easily.

Machine-washable padding — pets are often anxious during travel. Accidents happen.

Making the Carrier Feel Safe Before You Travel

The single biggest mistake: only bringing out the carrier on the day of a trip. Your pet immediately associates it with something unpleasant.

Instead:

1. Leave the carrier out permanently (or at least a week before travel)
2. Put a piece of your clothing inside — familiar smell = safety
3. Feed your pet near the carrier, then gradually inside it
4. Never force your pet inside — let them explore at their own pace
5. Take a few short "practice trips" before the real journey

A pet that voluntarily walks into its carrier is a pet that travels calmly.

Preparing for a Longer Trip

For journeys over two hours, have a plan for:

• Water access — travel bowls that clip to carrier doors, or a frozen water dish that melts slowly
• Toilet breaks — dogs need a stop every 2–3 hours; cats can typically manage 4–5 hours if litter-trained
• Familiar items — a favourite toy or blanket helps significantly
• Emergency supplies — keep your pet first aid kit and health documents in the car

If you travel regularly with your pet, keeping a packed travel checklist means you never forget the vaccination certificate, the medication, or the emergency vet number.
