Expandable Cat Carrier for 2 Cats – Airline Under-Seat 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.
At 25 cm (9.8") tall it's built to slide under the seat in front of you — the height limit most airlines enforce for in-cabin pet carriers. Every opening has lockable dual zippers whose twin pulls align through a cable-tie loop, the escape-proof closure airlines require for pets in cabin, and a luggage trolley sleeve slides over 24–28" suitcase handles.
Packed it measures 43 × 28 × 25 cm for pets up to 7 kg. Expanded it becomes 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. A firm base board plus a built-in fibre-rod frame means no sagging floor and no collapsing walls, with or without a cat inside.
4-sided high-density mesh gives mosquito-proof panels with natural cross-flow ventilation on every side, a top skylight hatch opens so your cat can pop their head out, and a hidden magnetic front door offers a quiet entry with no zipper noise for anxious cats.
One pull folds it flat to 8 cm — a third of its size — so it stores beside a wardrobe or under the bed. A padded grip handle and adjustable 70–119 cm strap allow hand, shoulder, or crossbody carry, and the lightweight 1.7 kg nylon body wipes clean.
Choosing the right size ensures your pet's comfort and safety.
Always measure your dog or cat carefully before placing an order.
Use a soft measuring tape to wrap around your pet's neck (A) and chest (B).
Place two fingers between the tape and your pet’s body to ensure a comfy fit.
If between sizes, we recommend choosing the larger size.

Quality is very good and better than a lot of cheaper carriers. I bought this to use on a flight. There are a lot of features, I like the multiple openings and the expandable parts. The privacy flap makes my cats feel more secure.
