Hamster ball for mice?

[Stewart_Reptiles]

I have just bought the most active mouse I have ever seen for my BP. My girl and I are staring at this mouse and it hasn't stopped running and jumping for 5 hours. I duct taped the holding cell to support it on the sides and laid it on the side. Now the mouse is running for an hour. After seeing this we are debating/discussing getting a mouse version of hamster ball for future mice. Our biggest worry is feeding our ball a mouse that is a gladiator. But since I always have him for approx~ 5 hours prior to feeding, I feel this is a good idea. In the pic you can see him running like a random hamster ball. My ideal end goal is to make the mouse so tired it limits opportunities to damage to the BP.

What a good idea when you hae a feeder that you buy and have it for 5 hours is actually the total opposite you want to feed it, give it water and let it relax, that's how you prevent injury and feed live, not by getting a rodent all wind up with exercise which raises adrenaline.
