Hi, We used to live in NC with our ferrets. There we cooled/heated the house with heat pump (yuk) anyway, we wanted to get the air flow, but keep our ferrets confined to master bedroom and bath. We took the door to the room d0wn and replaced it with a screen door. On the inside, I made curtains so our privacy was not lost. So when the ferrets had their out time, we had the screen door shut and curtains pulled back. We got the air flow, and could see the ferrets from outside the room if we wanted. When ferrets were up and we needed privacy, the screen door was shut and curtains would be down. It worked well for us there... Might give thought to doing that here too.
