Expandable Cat Carrier for 2 Cats – Airline Approved Under-Seat Travel Bag

The HiDREAM expandable cat carrier unzips at both ends into pop-up mesh tents, growing from a compact under-seat bag into a 97 cm lie-flat lounge with 50% more space — room for two cats, or one large cat or small dog up to 10 kg (22 lb). Fly with it, drive with it, then fold it flat to 8 cm when you're home.

A Cat Carrier That Fits Under the Airplane Seat

• 25 cm (9.8") low-profile height — built to slide under the seat in front of you, the height limit most airlines enforce for in-cabin pet carriers.
• Lockable dual zippers — every opening has twin pulls that align through a cable-tie loop, the escape-proof closure airlines require for pets in cabin.
• Luggage trolley sleeve — slides over 24–28" suitcase handles; zip the bottom and it doubles as a storage pouch through the terminal.

Room for Two Cats — or One Big Cat

• Packed: 43 × 28 × 25 cm for pets up to 7 kg. Expanded: 97 × 28 × 25 cm for up to 10 kg (22 lb) — two average cats, one large cat, or a small dog.
• Both tents unzip fully so pets walk in and out on their own — at your destination it becomes a covered den, not a cage.
• Firm base board plus a built-in fibre-rod frame: no sagging floor, no collapsing walls, with or without a cat inside.

A Soft-Sided Carrier That Breathes

• 4-sided high-density mesh — mosquito-proof panels with natural cross-flow ventilation on every side.
• Top skylight hatch — opens so your cat can pop their head out and watch the world.
• Hidden magnetic front door — a quiet entry with no zipper noise for anxious cats.
• Anti-escape safety clip — tethers to any collar or harness.

Collapsible & Travel-Ready

• Folds flat to 8 cm — one pull collapses it to a third of its size; store it beside a wardrobe or under the bed.
• Padded grip handle + adjustable 70–119 cm strap for hand, shoulder, or crossbody carry.
• Lightweight 1.7 kg nylon body that wipes clean.

FAQ

Will this cat carrier fit under an airplane seat?
At 25 cm tall it sits under most economy seats, and its length and height are within typical in-cabin limits. Every airline publishes its own carrier dimensions and live-animal rules, so always confirm with your airline before booking.

Can I use it for Virgin Australia's Pets in Cabin flights?
Virgin Australia accepts soft carriers up to 44 × 26 × 28 cm with pet + carrier under 8 kg. This carrier is 43 × 28 × 25 cm — within the length and height limits, about 2 cm over on width, though the soft-sided body compresses. Virgin measures carriers at check-in, so please confirm acceptance with Virgin Australia before you fly.

Is it big enough for 2 cats?
Yes — fully expanded it holds two cats with a combined weight up to 10 kg. They can stand, turn around, and lie flat in separate tent ends.

Does it work as a dog carrier?
Yes. Small dogs up to 7 kg fit in the packed bag; up to 10 kg with the tents expanded.

How small does it fold for storage?
The side-zipper frame folds the entire carrier flat to 8 cm — about the width of a hardcover book.
