This cage houses a pet rat and lots of enrichment accessories for her. While she doesn't use the ramps, I'm glad they're there to help prevent falls, etc
 The cage is sturdy and well built, and thr depth of the sliding bottom tray is good for her size and needs. I originally was looking at a taller cage, but this one is plenty tall and spacious.  I did have to measure each panel for assembly as they weren't labeled and all slightly different sizes. There was also one step missing from the directions, but I figured it out. Overall excellent product!
