Siivton Cat Carrier Expandable Built to Protect What Matters ## Features - DESIGNED FOR IN-CABIN TRAVEL: Specifically engineered to meet most major airlines' under-seat dimensions (18"x11"x11"). While the outer size is optimized for boarding, the internal cozy space is best for pets up to 15"L x 9"H. This precise design ensures your pet can accompany you in the cabin rather than in the cargo hold - IN-FLIGHT "FIRST CLASS" SUITE: Don't let your pet suffer in a cramped box for hours. While the compact design fits strictly under airline seats for takeoff, you can unzip the expandable sides during the flight to give your furry friend a spacious "private suite." This 4-way expansion provides 150% more room for them to stretch, turn around, and settle in comfortably, effectively reducing meowing and travel anxiety throughout the journey - MEASURE BEFORE YOU FLY: To ensure a seamless boarding experience, please measure your pet’s length and height. Weight (up to 15 lbs) is only a reference. Your pet’s comfort depends on their ability to lie down comfortably within the 15"x9"x9" interior usable space. If your pet is close to this limit, we recommend our XL size for non-airline use - VERSATILE TRAVEL COMPANION: Beyond the plane, it's a road trip essential. Features a luggage strap for airport navigation, seatbelt loops for car safety, and a reinforced handle. The entire bag is made of durable, breathable mesh to ensure your pet stays cool and calm in crowded terminals - EASY CARE & PRO-TIP: Includes a removable, machine-washable fleece bed for a fresh scent every trip. Note: As a high-precision folding product, please glide zippers gently during initial setup to ensure long-term durability of the expansion tracks ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07FY4PNTY | | Additional Features | Adjustable Shoulder Strap, Airline Approved, Breathable, Expandable | | Best Sellers Rank | #22,036 in Pet Supplies ( See Top 100 in Pet Supplies ) #46 in Cat Soft-Sided Carriers | | Brand | Siivton | | Brand Name | Siivton | | Closure Type | Zipper | | Color | 4 Extension Gray_Blue | | Compatible with Vehicle Type | Airplane, Bus, Car | | Customer Reviews | 4.3 out of 5 stars 8,933 Reviews | | Dog Breed Size | Extra Small, Medium, Small | | Included Components | 1 x Inside Pad,1 x Shoulder Strap | | Item Dimensions L x W x H | 18"L x 11"W x 11"H | | Item Type Name | Cat Carrier | | Item Weight | 1.4 Kilograms | | Manufacturer | Sivtoon | | Manufacturer Part Number | ST-A-EU0052 | | Material | Polyester | | Material Type | Polyester | | Maximum Weight Recommendation | 15 Pounds | | Model Name | Expandable Pet Carrier | | Model Number | LB01-L | | Pet Type | Bird, Cat, Dog, Small Animal | | Product Dimensions | 18"L x 11"W x 11"H | | Product Style | Modern | | Recommended Uses For Product | Airline, Camping, Traveling | | Size | 18.0"L x 11.0"W x 11.0"H | | Special Feature | Adjustable Shoulder Strap, Airline Approved, Breathable, Expandable | | Target Audience | Bird, Cat, Dog, Rabbit | | Target Species | Dog | | UPC | 712641825842 | | Unit Count | 1.0 Count | | Warranty Description | 12 Months Since The Date of Purchase | ## Product Details - **Brand:** Siivton - **Color:** 4 Extension Gray_Blue - **Material:** Polyester - **Product Dimensions:** 18"L x 11"W x 11"H - **Special Feature:** Adjustable Shoulder Strap, Airline Approved, Breathable, Expandable ## Images ![Airline Approved Pet Carrier, 4-Way Expandable Cat Dog Carrier for Under-Seat Travel, Soft-Sided Portable Pet Bag with Removable Fleece Pad, Fits Small Pets Up to 15 lbs (18"x 11"x 11") - Image 1](https://m.media-amazon.com/images/I/81w9IJI-lML.jpg) ![Airline Approved Pet Carrier, 4-Way Expandable Cat Dog Carrier for Under-Seat Travel, Soft-Sided Portable Pet Bag with Removable Fleece Pad, Fits Small Pets Up to 15 lbs (18"x 11"x 11") - Image 2](https://m.media-amazon.com/images/I/81-yY9RdI3L.jpg) ![Airline Approved Pet Carrier, 4-Way Expandable Cat Dog Carrier for Under-Seat Travel, Soft-Sided Portable Pet Bag with Removable Fleece Pad, Fits Small Pets Up to 15 lbs (18"x 11"x 11") - Image 3](https://m.media-amazon.com/images/I/51I8B4OSFTL.jpg) ![Airline Approved Pet Carrier, 4-Way Expandable Cat Dog Carrier for Under-Seat Travel, Soft-Sided Portable Pet Bag with Removable Fleece Pad, Fits Small Pets Up to 15 lbs (18"x 11"x 11") - Image 4](https://m.media-amazon.com/images/I/81noV9b1pjL.jpg) ![Airline Approved Pet Carrier, 4-Way Expandable Cat Dog Carrier for Under-Seat Travel, Soft-Sided Portable Pet Bag with Removable Fleece Pad, Fits Small Pets Up to 15 lbs (18"x 11"x 11") - Image 5](https://m.media-amazon.com/images/I/81MaRnji9ZL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: I'm flying with Southwest soon. Is this actually airline approved? It looks a bit bulky in the photos.** A: Yes! Zipped up, it's 18x11x11, fitting Delta, United & Southwest under-seat rules. The expansion is for during flight. I keep it zipped for boarding, then unzip in the air for more room. **Q: Can I actually open the expansion sides while the bag is under the seat during the flight?** A: Definitely! Once cruising, I unzip the side facing me. It lets my cat stretch into a "suite" under the seat instead of being cramped. It keeps them so much calmer and quieter on long flights! **Q: My dog is exactly 15 lbs. Should I get the Large or go up to the XL?** A: Measure first! Fits pets up to 15"L x 9"H. Weight is just a guide. Measure your pet while lying down. If they fit these specs, it's perfect for the cabin. For non-flight use, consider the XL. **Q: How are the zippers? My cat is a bit of an escape artist and I don't want her getting out mid-flight.** A: Very secure! They have a locking feel so pets can't paw them open. Pro-tip: Glide zippers slowly at first to align the track. Once broken in, they stay smooth and keep your escape artist safe. **Q: Does this have that strong "plastic" smell when you open it? Is the bed inside soft enough?** A: No harsh odors! Just air it out for a day. The fleece pad is super soft and 100% machine-washable. It’s a lifesaver for keeping the "travel suite" fresh and cozy after every single trip. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by K***E on February 18, 2022* ### ⭐⭐⭐⭐⭐ Review *by S***E on January 21, 2025* ### ⭐⭐⭐⭐ Review *by C***A on January 7, 2024* ## Frequently Bought Together - Siivton 4 Sides Expandable Pet Carrier, Airline Approved Soft-Sided Dog Cat Carrier Bag with Fleece Pad for Cats, Puppy and Small Animals (4 Extension Gray_Blue, L:18.0" L x 11.0" W x 11.0" H) - SLSON Collapsible Bowl with Cover Lids,2 Pack Dog Travel Bowls Portable Foldable Cat Water Dish Bowl for Pets Walking Parking Camping (Light Blue and Green, Small) - Portable Cat Travel Litter Box with Zipped Lid, Foldable Travel Litter Box, No Leakage, No Smell, Waterproof, Easy to Carry, Easy to Use in Hotels, Car --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/109664464-airline-approved-pet-carrier-4-way-expandable-cat-dog-carrier](https://www.desertcart.vu/products/109664464-airline-approved-pet-carrier-4-way-expandable-cat-dog-carrier) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-05*
