Your small pet’s every exercise need will be met with the help of this Trixie Wooden Exercise Wheel, made from natural untreated wood. Dwarf hamsters, mice and degus all have a natural instinct to exercise and often run many miles in the search for food. In houses and cages, these chances to run are naturally significantly reduced. This Trixie Wooden Exercise Wheel is smooth and low-noise, thanks to ball bearings. This means that your night’s sleep doesn’t have to be disturbed when your night-owl small pet decides to go for a midnight jog! The cork running surface is also a great feature, as it is safer for your pet’s joints and vertebrae. The enclosed back wall of the Trixie Wooden Exercise Wheel helps to prevent your pet from getting injured. The wide wooden platform can stand securely on the floor of a cage or outdoor enclosure. With this Trixie Wooden Exercise Wheel, you can offer your small pet the perfect opportunity to keep its fitness up and fulfil its natural running instinct.
