I'm in the market for a rack system. I had an animal plastics before but sold it when I moved to college. Now, I have two bps and lose tubs are just too much of a hassel for me. I cannot for the life of me find a two rack/tub. I can find 3 shelf at AP but no 2 shelfs anywhere. Its not a big deal, but I want to avoid the empty cage syndrome since I really can't afford another snake at the moment. Is there somewhere that does sell 2 animal units or is it just 3 shelfs? Thanks. I would make my own, but I'm not very crafty.
