We have
Freedom Breeder racks to house, feed, and water our rodents. We can not completely cover our own snake-food needs, but it does help us keep some healthy live rat and mouse feeders on hand. Our biggest kids who need rabbits are fed from purchases from a rabbit meat supplier. We have a few more levels than shown in the pics and we have the water supply connected to a pressure regulator so they have constant fresh water to each drawer.
