The Mouse Cubby Universal is designed to fit multiple cage designs (see compatible cages below). It fits snugly against the ceiling, floor, and wall to create three separate cubbies that open to a common area. Made of durable corrugated fiberboard, the Mouse Cubby is built as a disposable product that can be chewed into nesting material. This allows mice to creatively adapt and modify their environment, keeping engaged and minimizing aggressive behavior. This is a sample pack of 20 dividers. They are shipped Non-Irradiated.
