We have a protocol that has our mice running 3 hr/day. However, our Exer treadmill has some features that do not promote the encouragement of their running. In pic #1, you can clearly see a significant gap between the treadmill and the (non functional) shock grid - we tried putting test tubes in to fill the gap. I cut a thick (maybe too thick?) wooden dowel to fit in the gap, but that poses a problem because it is a perfect place for them to perch when they're tired. I then tried placing a dowel before the gap, but they still find a way to perch on it.
Does anyone have an idea on how to encourage running on this treadmill, and/or know a way to prevent them from falling in the gap? Thanks in advance to anyone reading, I encourage any creative ideas
Hi. I think if you increase speed gradually and train mice with lower speed for 3 day maybe mice habituated with target speed
we asked the same question from Columbus representative, they put kind of a white brick (caoutchouc) between shock grid but the gap was still there however, the mice ran better and didn't get stuck. Sorry don't have the treadmill anymore to show you a picture. Other thing was that like for human, we encourage them by tapping a little on the side of the treadmill from outside by a pen marker.
