The Critter Nation cage would be more suitable for rats, as it has 1/2" horizontal wire spacing. Please note, the Add-on unit cannot be used as a stand alone unit. The recommended amount of space in a cage for rats is 2 cubic feet per rat, including a floor area of 2 square feet. A single cage is approximately 12 cubic ft and 6 square feet, therefore about 3 large rats or 4 small rats would work comfortably in a single unit.
