1、High Quality Material: The hamster silent running wheel is made of heavy PS and acrylic materials, equipped with a non slip cork pad, and the base is safe and stable without displacement, meeting the running needs of mice. 2、Comfortable: The comfort of walking on a flat ground, the original parallel track design, the curved surface is 180° parallel and no oblique angle, to avoid the "long and short legs" of rats and mice when running, and to protect the health of the pet's spine. 3、Mouse Body Engineering: The size of the hamster's foot is generally 1x1cm, and the running wheel adopts a 1cm pitch gentle corrugated track design, which can effectively buffer the running speed and increase the friction force to protect the foot from slipping. 4、Quiet Design: The use of V3 high quality silent dual bearings, durable and more stable, can greatly reduce noise when running, and make it more silent. There is no "seam" connection, and the integrated design of the runway is safe and seamless without jamming. 5、Adjustable: The running wheel can be adjusted at any time, and the height of the running wheel can be adjusted freely according to the use space. The design of the surrounding outer rim, bid farewell to the right angled edge, to prevent rats from being thrown out when running.
