This cage was marketed as a ferret cage, but was used for rats. It's two levels with a ramp between levels. It's got a door on each level and has a metal tray at the bottom to catch litter. The bars are spaced so that each rectangle is 1" x 2", which was too big for my smaller female rats. Therefore, the cage was wrapped in smaller gauge wire and zap straps. This could easily be cut off if the original holes that the cage was made with are small enough that your creature can't escape. The cage is 30" tall, 30" long, and 14.5" wide. Can be available for pick up in either Sidney or Royal Oak, depending on the day of the week.
