This specially designed hamster wheel is designed with a solid running surface with lateral reinforcements for better grip preventing any blister damage on your hamster's feet. This silent style hamster wheel is a ball-like structure that rotates vertically enabling the hamster to continually run at the bottom of the wheel while its in rotation in a 'treadmill' type action. A running wheel is an essential accessory to support mental and physical stimulation while preventing boredom. This will add a pop of color to any cage. || * Material: plastic | * Colour: pink | * Safe to use | * Size: 110mm
