The ferrets love the room, the levels are great. I love the 2 large doors on each level, which makes the cage easier to clean and to get the ferrets out. I like the removable shelves.

Not so good.....One of the doors latches does not click into the of the cage frame. The cage rolls nicely, but there is some wobbling of the frame with this. If I put the bedding on the bottom level, the ferrets push it onto the floor.

Suggestion: The sides of the bottom tray would benefit cleanliness by being higher to prevent excrement from going over the sides of the cage. This would also keep the bedding from getting pushed out so easily by the ferrets. Is there a replacement tray with this idea?
