Rodents falling off the Barnes Maze

Many users of Barnes Maze find that there are problems with the animals either falling through the holes or off the edge, particularly with mice. The trick is quite simple - capping the holes. The design of the caps, is, however crucial as the animals must not be able to identify the escape hole from the other holes at a distance. The HVS Image Barnes Maze capping system is a very effective way of overcoming this problem.
