Thanks to Deborah for her rat rack design and her DIY. Well here is one of 4 racks. It turned out pretty good. I did change the casters I didn't use the same ones that are in the DIY. So the bottom looks a bit funky but it works. I have 3 females in each tub. I have enough rats to fill up 2 more racks with 3 females each. I can now start getting rid of the tanks.

It holds 6 jumbo cat litter pans. I might change to a water system when I get all the racks finished not sure. Thanks for looking.
