I have the same cage and almost the same problem (my ferts PUSH each other off the top). I make a huge hammock out of a flannel picnic blanket ( a large baby warming blanket will work too). I cut it into a trapezoid shape and cut slits in the corners (that forms the ties so that it can be tied to the bars). Then the short side of the blanket gets tied under the top ramp and extends under the top level. The long side gets tied against the back of the cage. Just remember to leave the blanket large enough to have some slack in it and play with it till it fits right. The trapezoid shape allows it to fit around the top ramp. You can get as fancy as you want with it-- use seam sealant (sewing dept.) or sew the edges to avoid fraying when you wash them. I don't bother since I just throw them away when they get dirty -- baby blankets are cheap. As for cleaning the bottom of the cage-- my ferts push food and litter into the sides. I use the hose attachment on my vacuum cleaner to suck everything up. Soon I will be getting a new vacuum so the old one can be used just for the cage since the bag fills up rather quickly. I suppose you could use one of those hand vacs that don't use bags. It doesn't get all the junk up all the time, but it is easier than taking the cage apart to clean it all the time.
