This cage is for my four rats. Its HUGE . lots of space to run around and play in. My rats love running up and down the ramp. Over all big . I love how the two doors open , its SUPER easy too clean. You just pull the pans right out clean them and put them back in. Some thing I disliked about the cage is it was hard to put together it took two strong people to manage to put the bars in place so everything fit. Its kinda of confusing but once you figure the base out its easy. Id recommend this to all people with rats!
