Okay so this has been bugging me for a long time and I want some honest, knowledgeable answers. The b word I'm talking about is breeders. NOTE: I'm NOT talking about intentional breeding itself. What I want to know is, what do ethical, reputable breeders do as far as setup and care? Do good breeders use rat racks? Cages? Do they provide in cage stimulation? What does a good breeders cage system look like? All the breeders I've ever seen use rat racks/bins. Is that normal?
