Very nice! I envy your larger space between the shelves. I made mine shorter and I have regretted it. It makes it so I have to be very careful about water bottle placement. If it is tipped up a little high and I open the tub above, it will either pull the licker out of the rubber stopper or pull the stopper out all together. Either way I have a wet mess or flooded out tub. Nothing like seeing pinky rats floating around!
One small recommendation, I would make some sort of a separated section on the screen for putting the food in. Something like a "T" of wood towards the front would be fine. It's just easier and cleaner looking that way.
