This would have been great for two rats, however I rescued a third rat.  It works but it is tight for the girls.  The downside to this cage is it is hard to clean.  The shelf do  not come out easy so I don't bother.  It doesn't fit in my tub at my apartment well.  If you have clean animal it may work great for you.  On the plus side it was east to put together and came quickly.
