Building rodent racks

I got sick of seeing my ghetto rack system for my rats so I decided it was time to build a rack here's my progress thus far.

Its a little late now, but I recommend you build it upside down starting at what will be the top. This allows you to keep it square all the way down. Also it will be easier at the end to level it if some of the boards have a slight warp/bow to them.

I am gunna go in reverse with this once since I only have a few tubs right now
