Our two chinchillas love this cage! It is spacious and lets us set up different areas for chewing, eating, hiding, and running. They have chewed one of the plastic pieces but it is still functional. The ramps are useless because they don't attach to anything, just rest on shelves so they fall down easily. But the chinchies hop from shelf to shelf easily. Easy to hang toys from the bars, and to attach their running wheel to the side of the cage. I also love that it has wheels and it is super easy to clean. Highly recommended.
