Bought this cage second-hand, and while it's not perfect, it's a not a bad cage for ferrets. The lower level is used for litter pans and allows for "accidents" to pass through the bars onto the tray below (I use puppy pee pads). Cleanup is relatively easy and quick. I prefer to not use the included bowl holders because my ferrets were able to knock them out and spill food/water. Bar spacing is more than small enough for ferret usage and most other critters with 1/2" spacing. I custom-cut carpet for the two upper levels to help keep my ferret's feet feeling great.. LOL!! :D In short, yes, there are better cages aimed specifically at ferrets, but at the right price, this isn't a bad option..
