Does anyone have any ideas for drainage for cages that have glass bottoms? mine is glass in the bottom and sides with the doors in the front and screen top. I didn't see any that would work for non screen cages in the forums.
You could have someone drill a drain hole in the glass. It takes a specific drill bit, but can be done. You could also tip the entire cage very slightly so the water collects in one corner making it easy to soak up with a sponge or towels.
