We brought our 2 Guinea Pigs home May 1, and made the mistake of getting the wrong cage. We got the largest one we could find, which in terms of square footage wasnt TOO far off from this one (but still too small)...the main problem was the that the ramp was impossibly steep, even though it was marketed for a guinea pig or other small pets. This cage is so much better, is actually cheaper, much MUCH easier to clean (especially paired with the Fleece Flippers, but even if you dont have them its still easier!) and is much more attractive. The kids had a great time picking out colors. Oh, and the ramp? After being hesitant for a few hours, they now hop and run up and down. We keep their hay rack, food bowl and water up in the loft area, giving them more room to play down stairs. All in all, a great set-up!
