Yes the pet doors are still in use. All the ladies wander in and out at their leisure. When we first put them in the pen and house we clipped the middle section of plastic up so they could see in and out. Once they started using the door regularly we dropped the center and they have been fine with it. Haven't made any changes to any of it .... well... have added a couple girls here and there, but the setup has remained the same all this time.
