A good carrier makes taking a rabbit to the vet or on trips far less stressful, keeping this nervous prey animal secure, ventilated and comfortable. The best have plenty of airflow, a secure escape-proof design, a stable non-slip base, and room for a little familiar bedding. We compared rabbit carriers, from backpacks to hard and soft carriers, on ventilation, security and comfort, so travel is as calm as possible for your bunny.
