Looks like the Feisty Ferret cage, it's very similar to the FN but only one door opens on each level, it's slightly smaller, and I've also heard they rust more then the FN. Also the plastic shelves, ramps, and metal grate on the bottom will need to be removed or have the pan inside the cage and covered instead of under it. I don't know if metal pans can be made for the FF or not, but even so you'd be better off just buying a FN instead, metal pans can be bought for those for sure.
