oh look at all those cute freckles!!!
i noticed the coloured bits of food in his dish - what brand of food and treats are you feeding?
edit - Rhino has that same cage (superpet chewproof), and the bottom floor grate comes out really easy, and having them on the metal pan is so much better than on the wire. plus, the metal pan stays cool, so it acts like a chiller tile. Rhino will flomp down on his pan after playtime, laying under his log house, to cool off. you could litter train your guy to go in a smaller pan (pyrex dish or metal mixing bowl like Rhino has) and that way he'd have more clear pan space to lay down or romp about on. and less shavings get used that way too! bonus! lol.
