You guys were right! The 55 gallon rubbermaid tub didn't last long, one week exactly. I purchased a x-large dog metal crate and used the bottom of that along with the cardboard box, added duct tape and wahlah! They were freaked out for a minute but now all is well with their lilttle planet and tons more room!
