The Marsh Designs Mouse Monitoring Cage is a scaled down version of our larger Rat Monitoring Cage. It measures 9 inches in height. The floor measures 6 by 6 inches, giving ample room for a freely moving adult mouse. The slide out lid has a 1 inch wide by 3 inch long slit to allow unobstructed pass through of any tethered line, yet inhibits the rodent from escaping. Seven 1 inch holes in the lid allow for adequate air exchange. The bottom of the cage has seven 0.38 inch diameter dowels spaced 0.35 inches apart. When the cage is lifted out of its tray, this patent pending design allows for sufficient support for even the stoutest adult mouse, while allowing soiled bedding to fall into the tray below.
