Got this for 2 Ratties.  I love the size of this.  Not as wide as a lot of the cages so it fits easier in the areas we are keeping the little girls.  There are two doors for easy access, cleaning the ramps and other areas is a breeze. The pan on the bottom slides out for cleaning.  I would not recommend this for ferrets.  It really seems too small I think they would go crazy in this cage.
