I need to expand my mouse colony, so I am going to be building a rodent rack.
When we build the snake racks that we've built, the spacing is obvious... just enough room for the tubs on each shelf.
I'm not so sure on the rodent racks. I plan on using the method of just piling food on top of the hardware cloth, and I also plan on using one of those watering systems. How much room is needed between the top of one tub and the bottom of the next for this to work?
