Ahhh, Breyer, you have the NICEST set up ever! I never get over how cool it is! If I was a rat, I would be over at the playpen area every day to play! Your boys are sooo lucky! You know what I noticed that just tickled me? Right next to the cutout section that is connected to their cage ramp (the door to the play area if you will) I noticed a little white cup/tub filled with what looked like little ratty toys? That was so precious! It looked like, "Hey, here is the boys' playroom and right next to the door is their toy box!" 
So sweet!! Fantastic set up. (And I loved hearing them munching in the background!)
