If you already own an 11 inch Wodent Wheel (make sure to measure asross the front of the wheel before ordering) should be 11 inches across to use this track, and wish to purchase just the running track to insert into the wheel we offer... The Sandy Wheel Insert™. You just pop off the outer cover of your Wodent Wheel, remove the regular running track, then pop-in the Sandy Wheel Insert. Leave the Wodent wheel with Sandy insert in your pets cage for 24-36 hours. When you are ready to switch back to the regular track, just reverse the process! Sandy Insets are washable, and typically last 6 months or longer before they need changing. Make sure to measure before ordering! Remember Sandy Inserts come in 3 different sizes, for the 3 different size Wodent wheels - 8 inch, 11 inch & 12 inch (size is determined by measuring across the front of wheel).
