I love this cage for 2 guinea pigs.  As others have said, it does not have a solid bottom, so be aware of that.  I ordered the plus which comes with a lid and dividerramp and have ended up using neither.  It seemed a little cramped to me and the guinea pigs didnt really get the ramp.  Maybe I should have given it longer.  Regardless, now its just one flat surface and they are very happy, even if I overpaid by 20 for features that arent used.
