Jo’s Pet Sizing Tip 🐾

Measure your pet before selecting a size—weight alone is not enough.

Measure your pet’s length from the base of the neck to the base of the tail, and their standing height from the floor to the top of the shoulders.

If your pet is close to the maximum measurements or prefers extra room, choose Size L. A verified buyer found Size L spacious and comfortable for their 6 kg cat.

Please allow approximately ±2 cm because the carrier is made from soft fabric. Buyer feedback also indicates that the finished carrier may be slightly larger than the listed measurements.

Size Guide

Size	Carrier dimensions	Approx. expanded width	Comfortable pet weight	Maximum short-term load
S	40 × 25 × 25 cm	65 cm	Up to 4 kg	Up to 5 kg
L	45 × 30 × 30 cm	82 cm	Up to 6 kg	Up to 7.5 kg

The side extensions are trapezoid-shaped, so a difference of approximately 1–3 cm between the top and bottom is normal.

For longer journeys, always select the size that gives your pet sufficient room to sit, turn around and lie comfortably.

More Space When Your Pet Needs It

Traditional carriers can feel restrictive during longer waits or journeys. The two zipped side sections open outward to create a larger resting area without requiring a permanently bulky carrier.

Keep the extensions closed while carrying your pet, then open them when the carrier is placed securely on a stable surface.

Designed for Calmer Journeys

The mesh sections allow your pet to see and smell their surroundings while remaining safely inside. The expanded sides can provide valuable additional room during waiting periods, making the carrier especially helpful for pets that dislike feeling confined.

Introduce the carrier gradually at home before travelling. Leave it open with familiar bedding or a favourite toy inside, allowing your pet to explore it at their own pace.

Frequently Asked Questions

What is an expandable pet carrier?

An expandable pet carrier is a soft-sided travel bag with zipped side sections that open to provide additional resting space. It can remain compact while being carried and expanded when placed securely on a stable surface.

What size should I choose?

Choose Size S for pets weighing up to approximately 4 kg during comfortable travel. Choose Size L for pets weighing up to approximately 6 kg or for smaller pets that need additional room. Always use your pet’s measurements as the main guide.

Is Size L suitable for a 6 kg cat?

Size L has a recommended comfortable load of up to 6 kg. A buyer also reported that the larger size was spacious and suitable for their 6 kg cat. Body length and height should still be checked before ordering.

How large is the carrier when expanded?

Size S has an approximate total expanded width of 65 cm. Size L expands to approximately 82 cm. Because the sides are trapezoid-shaped and the material is soft, measurements may vary slightly.

Can I carry my pet with the sides expanded?

Close and secure the expandable sections before lifting or carrying the bag. Only open the extensions when the carrier is resting securely on a stable surface.

Is it suitable for dogs as well as cats?

Yes. The carrier is suitable for appropriately sized cats, puppies and small dogs. Check both the measurements and recommended comfortable weight before ordering.

Does it fold away?

Yes. Its soft-sided construction allows the carrier to fold down for more convenient storage when it is not in use.

Can I take it onto an aeroplane?

Possibly, but approval depends on the individual airline and aircraft. Contact your airline with the carrier’s measurements before ordering, as cabin acceptance cannot be guaranteed.
