In my rept I made pole covers out of fleece with loops and then I hang a ferret litter box in one corner by chain and C clips and place their food dishes in that. The litter box has high sides and helps a little with catching the food. For the water bottles, I just made fleece holders that hang by the C clips from the loops.
I place a flour sack towel on the bottoms of my cages , change them every other day and use a cordless hand vac to clean the food particles every time I change the towels. I also have a piece of plastic under the cages so the floor doesn't get soiled.
Hope that helps!
