PETSFIT Single-Sided Expandable Airline Pet Carrier — Large Portable Pet Carrier for Cats
Product Overview
The PETSFIT Single-Sided Expandable Airline Pet Carrier is specifically designed for pet travel, combining ergonomic design with airline regulations to create a safe, comfortable, and spacious environment for your beloved pet. Its unique single-sided expansion structure not only increases interior space but also maintains the carrier's overall aesthetic and stability, allowing you and your furry friend to enjoy your travels together.
Core Design and Functional Features
External Frame for Sturdy Shape
This soft-sided carrier features a robust external steel frame design that effectively supports the carrier's structure. Even when expanded on one side, it resists deformation, ensuring your pet always has stable support and protection during travel.
Single-Sided Expansion Design for Flexible Space Adjustment
For various situational needs, we've designed a single-sided expansion feature that quickly increases the internal space:
Size S: Expands approximately 20cm on one side, suitable for pets weighing under 4kg. Carrier dimensions are 41cm (L) x 26cm (W) x 23cm (H), with a net weight of only 1.05KG.

Size L: Expands approximately 27cm on one side, suitable for pets weighing under 7.5kg. Carrier dimensions are 48cm (L) x 30cm (W) x 30cm (H), with a net weight of 1.35KG, providing a more spacious travel experience.
Breathable Design with Hexagonal Mesh
Featuring a hexagonal mesh structure with up to 70% mesh area, it achieves 360-degree all-around ventilation, effectively promoting air circulation and keeping the interior dry and fresh. It is also scratch-resistant and wear-resistant, ensuring long-term use without deformation or fading.
Safety Design and Multifunctional Configuration
Built-in Safety Leash Clip: Secures your pet's collar, preventing accidental escape while your pet moves inside the carrier.
Reversible Pad: Can be switched according to the season, suitable for both winter and summer, providing soft and comfortable bottom support.
Steel Frame Structure and Securing Straps: A sturdy steel frame combined with securing straps enhances the overall stability of the carrier, protecting your pet firmly even during travel vibrations.
Convenient Carrying and Airline-Friendly Design
This airline pet carrier complies with most airline regulations and is sized to fit under seats, allowing you to carry your pet with you during flights and share wonderful travel moments.

Many customers ask if we have hand-carry bags/cat carriers that allow pets to fly with people in the cabin. If the airline permits pets in the cabin, you should also check with the airline, as each aircraft varies in size, and the under-seat dimensions may differ.
If your pet is a regular pet, airlines usually arrange for them to travel as cargo. Some airlines allow them as checked baggage, while others require them to be transported via cargo services and cannot be carried as checked baggage.
Please note before purchasing: Pets Thing cannot guarantee that our hand-carry bags will definitely be allowed on board. Customers need to inquire with the airline beforehand and make their own decision. We will not be responsible for any consequences.
Please measure the required dimensions carefully. We do not accept exchanges, returns, or refunds for reasons such as incorrect product size after purchase.
If flying, it is recommended that you contact the relevant airline before your trip to confirm their specific requirements. We do not accept returns or exchanges for reasons related to airline refusal.
Space for pets on planes is limited; the number of pets allowed depends on the aircraft type, destination, and operating airline. Please book your pet's travel as soon as possible after booking your flight. The latest you should book is 48 hours before the flight departure.
