Not gonna lie…. It was very confusing for me to build but I suck at stuff like that. Other than that I LOVE it. My chinchilla is so happy in it. She runs around and plays all day because he has so much space. It offers the privacy chinchillas like and it looks so much better than those tacky metal cages. I didn’t attach the wheels because I wanted it to look like a piece of furniture and not like a cage because it’s in my living room. I definitely recommend it. It came in with minor dings but for the price who cares
