Here is our sump sink for cleaning, we have a garden hose valve for cage misting and water bowl cleaning. We also installed a ventilation system to keep the rodents from smelling up the room, it runs on a timer and ventilates the air five times a day for an hour each time.
This is a Hydrofogger, it runs off a Hydrometer that you set to the desired humidity, it is connected to the water supply and as needed it hydrates the room.
