Crap....no pictures of the glass part without the ports attached.
But see where the glass meets the plastic? The bottle actually narrows down there to screw into a tube inside the red part. That leaves quite an angle in the glass right behind the narrow part to clean--and that's where the mop comes in
If you want, and you remind me (
), I'll try to bring another feeder out of storage tomorrow and take a pic with the ports off.
I should bring in some additional feeders for cleaning, anyway.
