This collection has been a home for my chinchillas for the last few months. Tons of room and easy to customize. Lots of places to hang toys, hammocks and wood shelves. Wasn't as easy to assemble as I thought. There are black "stoppers" in the square corners as your putting it together that serve no purpose. You can either pop them out or get a mallet and screwdriver and pop holes in them, which is what I did. Went together just fine after making that adjustment. The cage is moved around a couple times a week to clean under and around it and it's held together nice. I also love that the doors are huge which makes it a breeze to clean. Would definitely recommend.
