This cage is fantastic. It's more than enough room for my two fancy rats. They have so much space to play and run around. It's a great layout and so easy to clean. The only downfall was the instructions. It was a pain in the neck to put together. Some of the holes weren't drilled all the way so I had to open some of them with my tools in order to fit the crews provided in. All in all, five stars if the building process was better.
