I went to the dollar tree to look for goodies. For rat ppl its like being a kid n a candy store. If u have one in your area EVERYTHING there is only a dollar. Y'all should check it out. They have these popcorn buckets that work great to cut a door in and put upside down on the ground or attach to the ceiling and be like a upper room. Mine love the one that is up high. Plus got plenty of other things for them. Just a heads up for my fellow broke rat lovers.
