Hi I just figured I'd post this as a new topic. I had posted a few cage pics on a different post and was asked about the treadmill. They can be purchased now.with rings to hand them from then top or side of cage. This is my best video attempt so far of one of the girls playing on it. Sorry they did not cooperate...if I turn the light on or open the cage door they always stop and look at me rather than keep playing. Hopefully you can make out the fuzz butt and get the general idea of how they run on it in the hanging position. :)
