Carrying a cat in a shoulder bag is fine for five minutes and miserable for an hour, which is the problem this solves. Wheel it through a station or a car park, then collapse the handle and wear it as a backpack up a flight of stairs or onto a bus — the two modes cover the awkward parts of the same journey.

The shell is 600D Oxford with a PVC water-resistant coating over a steel wire bracket, so it holds its shape rather than collapsing onto the animal inside when you set it down. Mesh panels keep air moving, which matters enormously to a stressed cat in an enclosed bag. The pull rod sets to two heights, the wheels are PU rather than hard plastic, and there is a safety strap inside to clip to a harness so a bolting cat cannot get out when the door opens.

Wheeling is not always kinder. Pavement vibration travels up a rigid frame and some cats find that more distressing than being carried. Try a short trip before a long one, and if yours objects to the rumble, use backpack mode on rough ground and wheels on smooth floors.

Who it's for: Cat owners facing longer journeys on foot, vet trips without a car, and anyone whose shoulders have had enough of a traditional carrier.
