Its actually funny. The bottom rat room used to be an ostrich barn. The top snake room was originally meant to be a guest home but we just filled the space with clay pots we were selling. Now the snake business is growing we are turning that into a snake room.
Very nice. I wish I had a place to breed rats. I also wish I had the space for breeding that you have. My breeding room is a 12'X12' room in my basement, but it suits me fine for now. Yours is outstanding.
