Review on Habitrail 62635 OVO Club Trainer by Tiffany Love

Disclosure: Bought a lot cheaper as an item from Revain's inventory. I didn't want to pay full price for it. When I saw that one of these was less than half the price due to a damaged box, I took the plunge. He's bigger than I thought. It goes straight to another Habitrail connection that I previously connected to the terminal. I'm concerned that the open groove that runs all the way around the bottom will catch my mice's paws. It would be like a human treadmill with a groove down the middle bigger than the width of a boot. There is a very real possibility that one of my mice could get its feet stuck in it during use. Some of them run as fast as they can on other bikes I have and don't care where they step. They become so addicted to it that they sometimes turn around and run off the wheel. However, I've never had the chance to see if the mice like it or hurt themselves. 4 mice have access to this and less than 24 hours after I installed it they took the litter and completely plugged the hole so none of them could access it.
