#1) The Bin cage
•Used by many reputable breeders, and rat owners alike.
•Affordable/Low-cost
•Safe; super easy to clean & maintain.
•Custom & Requires minimal space: I recommend that you make a bin cage with 3-wire ventilation windows; 2 side windows, and one on the lid. This allows you to stack or place cages side-by-side without any worries of good air flow.
