A hamster in a shoebox with holes punched in the lid is a stressed hamster who cannot see out and an owner who cannot see in. This is the small step up from that: a soft ventilated bag with a clear bubble window in the side, so the vet trip happens with the animal visible and the air moving rather than in the dark. The shoulder strap keeps both of your hands free.

Ventilation is the thing that genuinely matters for small pets in transit. Guinea pigs, hamsters and gerbils overheat quickly in a sealed container and cannot pant their way out of it, so mesh on more than one side does more for their welfare than padding ever will. The bubble window adds a lookout without adding another opening to escape from, and the closure fastens properly rather than relying on a loose flap. The bag itself weighs 200g, so it adds almost nothing to the load.

• Secure closure
• Adjustable padded shoulder strap for hands-free carrying
• 200g empty
• Ships in a 27 x 12 x 6cm package

On size, and on how long. This is a carrier for short journeys to the vet or between homes, not a travelling cage. For anything over an hour a small animal needs room to turn, water, and something hard-sided.

Who it's for: Owners of hamsters, gerbils, rats and similar small pets making short, occasional trips.
