I like the leaf. It's a nice touch
Anyway, it looks great! I'm thinking about putting together a similar setup for my rats. I have them in large chinchilla cages right now, which is a major pain to keep clean, and one of my colonies has this really weird habit of pushing 2-3 day old pinkies out of their cage through the bars x.x My only concern with your setup would be that I've heard a lot about how loosely scattered food on top of grating can be difficult for the rodents to grab hold of and eat, and thickly scattered food can restrict air flow. I think when I do it I'll put a small cross-bar about 1/4 to 1/3rd the way across the screen so I can pack just that section with food, so the weight of food on top holds the pieces on the bottom still against the mesh.
