pg...been toying with the idea of making a custom cage with a screen panel that can be slid into the portion of the top of the cage, but below the installed nozzle giving you the same effect as a rain nozzle but with nothing on the outside of the cage. Few problems though...taking away real estate from the animal, hard to apply that for existing cages, animals/feeders possibly getting stuck behind the panel, etc. I found the whole concept flawed as it was too intrusive into the cage and that's what everyone is trying to avoid. Maybe has some merit, just needs to be tweaked,
